FR and space guaruntee on a SnapMirror volume

community@netapp.com — Wed, 18 Nov 2009 18:05:38 GMT

Hi,

Is it possible to set space guarantee to NONE on a snapmirror destination volume which has Fractional Reserve set to less than 100%??

Originally we had an SQL vol with FR set to 100% which we snapmirrored. The destination vol was not thin provisioned, and therefore every time we resize the source vol we have to also resize the destination.

However, now we have reduced the FR to 50% and enabled snap autodelete and vol autogrow - sounds good and works fine. But the problem is that if the vol autogrows, the source will be bigger than the target and snapmirror fails. My way around this was to set space guarantee to NONE on the target volume and thin provision it (so if the source autogrows, the target won't care as long as there is space in the agg).

I am having trouble configuring this though as I see that space guarantee apparently cannot be set to NONE if the FR is less than 100%??? (and when I try and do this on the destination volume it gives an error). Also, it seems that the FR setting gets copied from the source and has to be the same at both ends - so I can't change FR on the target to 100% without also changing it on the source?!

Anyone got any suggestions on the best way to manage this?

Or does the vol autogrow setting that we enabled on the source also mean that the snapmirror target will also autogrow automatically and therefore I don't have to worry about thin provisioning it? (I can't believe this would happen).

Help as always much appreciated!

Why am I getting a Bad Disk Label Error?

community@netapp.com — Tue, 17 Nov 2009 15:41:33 GMT

I recently replaced a failed disk with another spare that I had but when it was inserted this is what I get: "disk has no valid labels. It will be taken out of service."

"1 disks have downrev firmware. They will be updated automaticaly using...."

This filer is an F820. The disk is a 68.0GB 520B/sect.

What can I do to correct this?

Thanks,

community@netapp.com — Wed, 08 Jul 2009 09:42:34 GMT

I have problem to access NetApp snapshots on Windows 7 in “previous version tab” and anyone has this experience? Do I need to configure anything in OnTap to make this works?

comparable model to ds3400

community@netapp.com — Thu, 19 Nov 2009 19:56:21 GMT

Hi,

Which Netapp model can be compared with speed to DS3400?

Is 2020 slower?

Is 2050 maybe?

Thanks

Raid group size recommendation

community@netapp.com — Fri, 11 Jul 2008 10:29:04 GMT

Hi Folks,

I'm trying to design a storage solution.

A FAS3020 with 3 shelves full with 42x 300GB FC disks.

Default the Raid Group size is 16 (14 + 2 spare) de max raid group size is 28.

Does anyone have some best practice information? The NOW site hasn't much info on that.

Kind regards

HOSTS authentication problem

community@netapp.com — Tue, 27 Oct 2009 17:18:05 GMT

I'm trying to use host-based authentication (h

osts.equiv), but it's failing. I get the error:

"User does not have capability to invoke API quota-report."

If it's not clear, there are two spaces after 'User', as if it were printing a null username. Sure enough, from the log:

Tue Oct 27 11:44:14 CDT [near19: useradmin.unauthorized.user:warning]: User '' denied access - missing required capability: 'api-quota-report'

Am I missing something?

Qtrees capacity don't show up in DFM

terrence.lee@netapp.com — Wed, 18 Nov 2009 01:59:47 GMT

Hi,

I just found out that there are several qtrees of few filers don't have the qtree capacity shown in the DFM. I have checked the qtree quotas are set and quota turned on. The DFM version is 3.7.

Any idea?

New FAS 2050 Install

community@netapp.com — Mon, 23 Feb 2009 21:40:50 GMT

Hello All,

I just ordered a FAS 2050 12TB with SATA drives and 2 controllers. I am looking for configuration documentation or anything else that can help me get things up and running. I am replacing a S550. We are running 2 ESX servers with NFS connection back to the S550.

Is their a serial port where I could assign a IP address instead of using the Easy FAS wizard. Then use filerview to finish the config. I would rather do things manually to get a better understanding of what is going on.

Any help that could be provided would be greatly appreciated.

New FAS2050 poor iSCSI performance in ESX4

community@netapp.com — Thu, 19 Nov 2009 20:33:56 GMT

Greetings! I am new to iSCSI and I just installed a new FAS2050 configured with dual filers and all 15K SAS drives. It's configured for Active/Active and the disks are split evenly between the 2 filers. I created a 300 gig volume for VMWare on the first filter (fas2050a).

The clients are ESX4 servers, 2 new HP DL385G6 machines and 2 HP DL380G6 machines.

The switches dedicated to iSCSI are 2 ProCurve 2910AL-24G with 10gbit link between them.

Here are the relevant lines from the switch config.

interface 1
   name "FAS2050a_e0a"
   flow-control
exit
interface 2
   name "FAS2050a_e0b"
   flow-control
exit

trunk 1-2 Trk3 LACP

spanning-tree Trk3 priority 4

The DL385s are configured with 8 gbit NIC ports. The DL380s only have 2 (will upgrade later).

The filer fas2050a has both nics connected to one of the switches and are configured as virtual interface vif0 for lacp. Within that virtual inteface I created a virtual interface for vlan 100 and have the switch ports trunked for LACP tagged vlan 100. All interfaces that will be used for iSCSI are setup for an MTU size of 9000. vif0-2 is for our normal "server" vlan segmant and has iSCSI disabled.

fas2050a> ifconfig -a

Since the DL380s only have 2 nics their configuration is simple so I will keep to that for now.

I hace 2 virtual switches with a single nic assigned to each. vSwitch0 is for the sevice console and VM Network, vSwitch1 is for the iSCSI software HBA. I configured both vSwitch1 and vmnic1 for a MTU size of 9000.

[root@ushat-esx03 ~]# esxcfg-vswitch -l

PortGroup Name      VLAN ID Used Ports Uplinks
iSCSI_VMkernel0     100      1           vmnic1

vmnic1 has been properly bound to the iSCSI software hba.

The test is copying very large files such as ISOs or server images from machine to machine through the local vswitch, or "migrating" virtual machines from the ESX server's fast local storage to the FAS2050 and back.

Here is a sample sysstat output from the filer while copying a 5 gig image file from a file server on the local network to a virtual machine hard drive on the SAN. The numbers are often much lower when migrating a VM from local to iSCSI.

It seems the performance tops out around 60-70 MB/s with rather high CPU usage on the filer. My understanding was we should see closer to 120 MB/s when using gigabit and jumbo frames. When disabling jumbo frames there is hardly any impact on performance.

The performance is a little better when testing on the DL385s where I have 4 nics dedicated to 4 seperate VMkernels with round robin providing 4 active paths (following TR-3749 as a configuration guide)--about 80-90 MB/s.

Am I right to assume we should be seeing quite a bit more throughput from this configuration? I was hoping to see >120 megs/sec since I have 2 gigabit nics in the FAS2050 filter in a LACP trunk, and 4 nics using round robin on the ESX servers AND using jumbo frames.

Any suggestions?

Using NFS over iSCSI for VMware access

community@netapp.com — Mon, 05 May 2008 08:30:07 GMT

We have recently moved some of our application server to Vmware ESX server. For the datastore we have used Netapp filer. I have NFs license on Netapp system, so I was wondering about what we should use to access the datastore, I mean whether we should use iSCSI or NFS. It seems majority of people uses iSCSI and even Vmware engineer suggested that, while Netapp saya that on NFS the performance is as good as iSCSI, and in some cases it is better. Also I knew that Netapp NFS access is really very stable and perfornace freidnly, so I have choosed NFS to access the datastore. The additional advantage which I have got is that I donot need any snaprestore or any other license to restore the backup. Becuase in NFS, we have all the snapshot copies accessible directly under .snpshot directory, so we have created scripts which takes snapshot every 15 nins for very critical servers, so anytime if I have an issue, I can get the last 15min snapshot copy, and make it a production copy in a mater of seconds.

Now my question is have any customer have done some real testing to prove that NFS access is atleast equivalne tot iSCSI performance if not better. Becuase in times to come, the load on our application server will increase only, so I want to make sure that my decision was correct.

Default Snapshot reserve

community@netapp.com — Mon, 13 Jul 2009 18:43:20 GMT

Hi folks,

I have no idea whether this question is in the right location, but if not please relocate it or tell me where it should be.

I have always been told to set the default Snapshot reserve at 20% unless a specific environment requires a different setting.

Also it looks like Netapp's Synergy program views 20% as being the standard.

Can anybody tell me what the reasoning is for this 20% default value?

I am not questioning it's validity, I am just intrested how it came to be this value.

Thanks,

Mark

Netapp snapshots & VMWare snapshots

community@netapp.com — Mon, 31 Mar 2008 14:04:43 GMT

We use Netapp snapshots/snapvault as a way to take backups of VMs.

This is done using a script that does something like this:

1. look for all VMs on a datastore

2. take a VMWare snapshot of all VMs on that datastore to quiesce the .vmdk file

3. take a netapp snapshot of the datastore

4. delete all VMWare snapshots taken in step 2.

All of this is done to ensure that the .vmdk file is not written while taking a Netapp snapshot.

Now, I'm wondering: as far as I know, the NetApp snapshot is an atomic action for an entire volume. So does it actually make a difference to quiesce the VMs beforehand, given that all .vmdk files of a VM are on the same volume ?

We've been successful in restoring non-quiesced .vmdks so I'm wondering if anybody has an opinion on this.

SnapManager for SQL SnapInfo sizing

community@netapp.com — Mon, 05 Jan 2009 16:34:17 GMT

Does anyone have any solid SMSQL snapinfo volume sizing guidelines? The SMSQL admin guide does a good job explaining sizing for the databases, logs but not good at all for sizing the snapinfo directory.

http://now.netapp.com/NOW/knowledge/docs/SnapManager/relsmsql211/html/software/admin/plandat4.htm

Is there a formula that I can use for snapinfo? There's one for database and logs volumes but not for snapinfo. I find myself totally guessing what this number should be when doing snapmanager work for a client. How are we supposed to come up with an accurate snapinfo lun and volume size?

Any suggestions?

Cheers

VSS Components Conflicting?

community@netapp.com — Wed, 18 Feb 2009 06:02:23 GMT

Hello,

I have a question about VSS providers potentially conflicting when backup up a VM via VIBE.

Using the following software:

ESX 3.5 U3 + current patches

Guest: Windows 2003 Standard SP2

SQL 2005 SP2

SnapDrive 5.01

SM:SQL 2.1.2

VIBE 1.08

VMware Tools are up to date, with the VSS sync driver installed.

OnTap 7.2.4 and 7.3.1 both produce the issue

When VIBE kicks off, and calls VC to snap the SQL VM, it seems to trigger the OnTap VSS Providor to clone the LUNs and try to present them to the OS.

The production LUN never goes offline, nothing seems impacted. I'd just rather avoid this thrash if possible. Can I somehow specify which volumes apply to each VSS Hardware Provider, or disable the SQL Volumes from being quiesced by the VMware Tools VSS script?

I did lots of searching tonight with little luck, I'm sure someone has seen this before?

ndmp copy from 3040 to a Storevault

community@netapp.com — Wed, 11 Nov 2009 12:49:40 GMT

I connect to my SANs from a linux box with RSH.

I run a script in cron nightly.

Basically what I want to do is backup volumes on the NetApp 3040 to SATA disks on my storevault. Here is the command:

rsh mysan ndmpcopy -sa root:password -da root:password -l 0 /vol/myvolume mystorevault:/vol/myvolume_bak

So I am copying /vol/myvolume to /vol/myvolume_bak with a level 0 ndmpcopy.

These volumes contain VMware VMDKs.

I don't really understand the different levels of ndmpcopy. I don't understand how it copies. Does it delete the contents of the source first? Does it overwrite files and folders one at a time? Does it copy everything over and then start deleting from the destination?

The volume on the 3040 is deduplicated so I expect the data on the storevault to to be bigger in size (no dedup on the device).

However every day the sizes of the storevault data keep fluctuating. For instance the volume on the 3040 is 160GB used out of 200GB. I created a 250GB volume on the storevault. Yesterday after ndmpcopy it showed just over 168GB used. Today it is showing 80GB used. So today the backup is smaller than the source. I have also seen the destination volume go to 100% used one day, 0% the next day and an expected amount comparable to the source the following day.

Bottom line is I expect the data in the backup volumes to be fairly consistent. Can this be done with ndmpcopy? Can it copy like rsync, just do the changes?

The other option I have is destroy and create the backup volume each night.

Thanks

Does anyone know how 8.0cm is going to achieve SSI?

daniel.fedick@ironbrick.com — Thu, 19 Nov 2009 19:00:56 GMT

I get that there is a global namespace for NFS and for CIFS and that all the systems are sharing a global IP across all the systems.

In the "Data ONTAP 8.0 Cluster-Mode" white paper there is a statement that says the following:

"By offering a single system image across multiple storage nodes, the global namespace eliminates the need for complex automounter maps and symbolic link scripts."

Are they saying that all controllers in the cluster have access to all the disks? If so, are we now creating a SAN between all the controllers and storage shelves in the cluster?

My assumptions are that each storage system has access to it's disks and the "Cluster-Mode" is only a statement in regards to the front end (I.e. NFS / CIFS Global Namespace.)

Does this sound correct?

How to resize a snapmirror volume?

community@netapp.com — Thu, 12 Feb 2009 17:12:22 GMT

Hi Everyone,

Can someone point me to instructions on how to resize a SnapMirror volume?

We have a 600Gb volume that we are mirroring from a FAS2020 in SiteA, to a FAS2020 in SiteB for backup.

Today I had to resize the primary volume in SiteA as it was running low on space. However, when I try to resize the mirror of this volume in SiteB it gives an error because the volume is "read only".

I've heard that the correct way of doing this is disabling the mirror, change the read-only state on the SiteB mirror via the command line, resize the volume, mark it read-only again and then restart SnapMirror - any ideas on how to actually achieve this would be great!

(and there I was thinking I'd quickly resize both volumes and "hey presto" everything would take care of itself! ).

Thanks,

Marc

SMVI VMware snapshots not committing

community@netapp.com — Fri, 14 Aug 2009 22:18:39 GMT

I have been having an issue with the vmware snapshots generated by SMVI. On certain backup attempts by SMVI the VMware snapshots are never removed. It doesn't seem to matter whether the smvi job is successful or not as I have seen it not clear snapshots in both cases. The attached .bmp file shows the three uncleared snapshots from three different dates. The logs are from two different servers that had uncleared snaps that happened to be on the same day. I couldn't go any earlier as the smvi logs "could not find the backup id."

What seems to be the recurring issue:

2009-08-09 = 08:02:28,244=20 INFO - FLOW-11012: Operation requested retry
2009-08-09 08:02:38,306 = INFO -=20 FLOW-11006: Starting operation in threadpool backup

This repeats for several minutes and then it looks like it just gives up. I have most smvi backups kicking off at the same time - not sure if that could be a relevant factor.

Anyone else experiencing similar issues?

FAS270 Filer and Domain controller clocks are more than 5 minute apart.

badoem@willis.com — Thu, 18 Jun 2009 09:30:15 GMT

Hi All

I am abou to embark on NS0-163 exam in July. My friend has leant me his FAS270 Filer to familiarize myself with building a filer from scratch. I have hit a stumbling block already and would need some assistance please.

Basically, I have built a Domain Controller called with AD and DNS called DIR.LOCAL, IP address of 192.168.0.100. I have added my new filer to DNS, its called GBIPS-I-FS1, IP address of 192.168.0.100. I have also added it to Computers in Active Directory.

I then re-initialized the disks on the Filer to set up from scratch and went through the set up process till I got to the authentication aspect. Basically I have pasted the messages I am getting regarding Time services not configured on Filer, then filer and Domain Controller are five minutes apart.

Would someone please give me some further assistance to get this filer configured, so I can be on my way to prepare for the exams. Any help will be valuable

Thanks

Manny

Monitoring NetApp

community@netapp.com — Tue, 10 Nov 2009 03:07:26 GMT

I'm running a FAS2020 with DataONTap 7.2.4. I'm running into some

performance hiccups and wanted to take a look at what my options are to monitor my SAN. I've looked a bit through the MIB list for SNMP but am having a hard time discerning what I should be looking at to determine performance issues.

Additionally, can someone please help explain what some of the sysstat information is? What are the implications of cache age and cache hit? What about the CP Time?

Appreciate the help!

Question regarding ChkSgFiles.dll in Exchange 2007

community@netapp.com — Thu, 29 Oct 2009 15:15:36 GMT

Hi,

I have a couple of Windows 2003 Lab Servers running Exchange 2007 with SME 5.0 and want to use ChkSgFiles.dll instead of eseutil for Backup Verification.

From what I read my understanding was that in an Exchange 2007 environment ChkSgFiles.dll is used automatically but if I check the backup logs, eseutil is used for verification. I changed the Registry Key HKLM\Software\Network Appliance\SnapManager for Exchange\Server UseCheckSgFilesVerify to 1 and restartet the server but eseutil is still used to verify the backups.

What do I have to change that ChkSgFiles.dll will be used by SME ?

Thanks

x64 SnapDrive 6.1.0 2593 - Not Working On x64 2008 Server

community@netapp.com — Fri, 04 Sep 2009 10:21:50 GMT

Hi,

I am running OnTap Simulator 7.3.1.

I cannot connect to volumes on the simulator from x64 based Server 2008.

I receive various messages at various times doing various tasks:

Task: Create Disk

SnapDrive Error:

Error: The remote server has been paused or is in the process of being started.

Task: Create Disk

Error: Failed to get Data OnTap version running on the storage system 'IP Address'

Error Description: Can't connect to host (error=10061)

I have attempted to use all transport protocols http, https & rpc and the filer is joined to the domain and the domain accounts are in the local admins group on the filer and server. I have also tried without the filer being connected to the domain using local accounts for pass through auth.

When I install the same version of SnapDrive on a x64 2003 Server I can connect to same volumes and create disks without any issues.

This must be a compatability issue with 2008 server, however I do work with the same version of SnapDrive & 2008 in a production environment without any issues.

Is this a simulator + 2008 issue ?

Any help appreciated.

Thanks

Error 145 states that there is a network problem but we have connected a windows machine on the same switch using same cable but we live no problem and performance is well.

My questions are:

1) What is the best practice to use Solaris10 mpxio+iscsi
2) Why we get above errors? Maybe I must change default values for target (netapp). Anyone here in this list have experience for that?

aggregate / vfiler migration

community@netapp.com — Mon, 12 Jan 2009 12:11:06 GMT

Hi All,

I'm trying to put a plan for aggr/vfiler move to a new filer.

senario;-

I have a 3070 filer, has 1 vfiler and has 2 aggr inside it with FC disks.

Plan to move to a 3040 Cluster filer with 2 aggregates pointing to 85disks, now with 3040 head, how can i make sure that vfiler is migrated with its quotas and cifs shares are

intact...any pointers to such process already done is of great help.

i have read vfiler migration..but that does not talk with this context...

regards

rajesh

54.6 MB/s iSCSI GbEthernet between Linux (RH5) and FAS2020

community@netapp.com — Wed, 11 Nov 2009 13:02:23 GMT

average 54.6 MB/s is normal speed for GigaEthernet ? ( I have just FAS2020 -> SwitchEnterasysC3(HighSpeedGigabitEthernet) -> Linux(broadcom GigabitEthernet) )

When I tried to use dd to force write data in FAS2020 the process is used 100%, this is one bottleneck problem or this is normal ?

SnapDrive process failure in Linux

community@netapp.com — Fri, 25 Jul 2008 14:52:32 GMT

Hi all,

I'm deploying a new filer and am having some troubles with SnapDrive 4.0 for Linux - specifically CentOS 5.1 x86_64 (fully patched).

snapdrived starts up ok and I can interact with it to the extent of setting the root password for the filer. When I try to perform a filer operation, however, things don't go so well. To start,

[root@db2 log]# snapdrive storage list -all

Status call to SDU daemon failed

[root@db2 log]# ps -ef | grep snapdri
root 7587 1 0 Jul24 ? 00:00:00 snapdrived start
root 11283 7587 0 13:40 ? 00:00:00 [snapdrived] <defunct>

Each re-iteration of a snapdrive storage command will spawn a new defunct process. Commands such as "snapdrive config show" will run fine.

And in sd-trace.log:

13:43:06 07/25/08 [f7f7cb90]?,2,2,Job tag: bEogRP90xw
13:43:06 07/25/08 [f7f7cb90]?,2,2,snapdrive storage list -all

When I strace the snapdrive process I see things conclude with:

connect(3, {sa_family=AF_INET, sin_port=htons(4094), sin_addr=inet_addr("127.0.0.1")}, 16) = 0
send(3, "POST / HTTP/1.1\r\nHost: localhost"..., 1555, 0) = 1555
recv(3, "HTTP/1.1 200 OK\r\nServer: gSOAP/2"..., 65536, 0) = 1722
shutdown(3, 2 /* send and receive */)   = -1 ENOTCONN (Transport endpoint is not connected)
close(3)                                = 0
write(2, "Status call to SDU daemon failed"..., 33) = 33
munmap(0xf7f7d000, 135168)              = 0
exit_group(104)                         = ?

Which follows what I see on the packet capture side of things where the snapdrived port sends RSTs (no doubt after the child process has gone defunct) after a very limited exchange:

POST / HTTP/1.1
Host: localhoHTTP/1.1 200 OK
Server: gSOAP

Any input appreciated.

Thanks in advance.

SNAPDRIVE 6.2 & Snapmanager for Hyper-V BETA

community@netapp.com — Wed, 11 Nov 2009 14:24:52 GMT

Hi everyone. Does anyone know how I can obtain a beta/trial version for SD 6.2 & Snapmanager for Hyper-V? I am interested in these two softwares as I am currently running Hyper-V in a Clustered environment. I have found a lot of bugs in SD 6.1 & would love to see if these are fixed in SD 6.2. I would also like to see what are the backup/restore capabilities for VMs using the new snapmanager for Hyper-V. We are doing some creative backup/restore using a combination of a 3rd party software along with snapmirror.

CIFS security

community@netapp.com — Thu, 21 Aug 2008 11:28:54 GMT

Hi,

We have a fresh installed netapp running on DATA ONTAP 7.3.

But there is an issue with our CIFS security. the netapp is joined to the AD domain and Qtrees are set to NTFS.

We made our CIFS shares and set the security in the webUI.

Which works great, the users/groups we added can access the shares.

However, as a domain admin, Ive setup different security on subfolders in that share.

But they do not seem to have any effect! it seems the security i set up on the CIFS share pushes trough all the subfolders.

In windows, Ive ticked "inherit from parent permission bla bla" OFF on the subfolders.

Any ideas?

Many thanks,

Antony

DSM for Windows MPIO and iSCSI

tom.bebee@siriuscom.com — Tue, 16 Sep 2008 13:03:39 GMT

We have a customer condering SnapManager for Exchange, which will require SnapDrive for Windows. They will be using iSCSI protocol for data access. I realize that for multipathing on the Windows hosts, the customer could use Microsoft's multipathing, but from the reading I do, it seems like NetApp DSM for Windows MPIO will be a more robust solution. My questions are:

1) Does the NetApp DSM software include both FC and iSCSI drivers?

2) Does installing SnapDrive require multipathing on the host? (my understanding is that it does)

3) Does the SnapDrive software include the NetApp DSM software or does it need to be licensed separately

Thank you.

How do I backup snapshots to tape?

community@netapp.com — Sat, 25 Apr 2009 04:36:03 GMT

I am using NetBackup 6.5.3 to backup my NetApp filers to tape for longer term data retention via NDMP over our SAN. All the filers see the robot and all drives just fine. In fact, when I do run backups, everything works fine. The problem is, I don't get any of my snapshots. From what I have read, once the backup is initiated, it triggers a snapshot of the active WAFL filesystem on each filer and backs up that snapshot only. I could care less about the active filesystem.

We are running SMVI and I want to backup those snapshots to tape for longer term retention. How do I do this? For instance, if I have snapshots on /vol/vol1, how would I backup the most recent snapshots taken or snapshots taken that day? Would backing up /vol/vol1/.snapshot work (I know this would probably be VERY inefficient space wise)? Or, would I have to write some script called by NetBackup to interface with SMVI to get the most recent snapshot taken? I have seen examples with SMO where administrators have established a snapshot naming convention and rotated snapshots from within scripts. For example, if 7 snapshots are kept, the most recent is called snapshot.recent and then all other snapshots are renamed to snapshot.1, snapshot.2, etc. with the oldest getting deleted. Thus, you are always backing up /vol/vol1/.snapshot/snapshot.recent.

How do you backup snapshots to tape? Again, when the backup is finished from NetBackup, no .snapshot directory exists to restore from. Any help would be greatly appreciated.

Anonymous FTP

community@netapp.com — Thu, 09 Apr 2009 13:17:42 GMT

Hi!

I've been trying to get FTP file access going by means of anonymous FTP login, but something's a miss... It's ONTAP 7.2.5.1 simulator - and I've followed all the steps described in http://now.netapp.com/NOW/knowledge/docs/ontap/rel7261_vs/html/ontap/filesag/index.html , under "File access using FTP" section. Here it is, in short:

options ftpd.enable on

options ftpd.auth_style ntfs

I've created a volume called "vol1", with a qtree named "anonymous" and entered the path into the /etc/cifs_homedir.cfg file: /vol/vol1/anonymous

cifs load homedir -f

options ftpd.anonymous.enable on

options ftpd.anonymous.name anonymous

options ftpd.anonymous.home_dir /vol/vol1/anonymous

In the end, I've tried creating an FTP connection from my laptop to it but I got the following error report:

     C:\Documents and Settings\Laptop>ftp 192.168.0.130
     Connected to 192.168.0.130.
     220 simulator FTP server (NetApp Release 7.2.5.1: Wed Jun 25 07:59:11 PDT 2008)
     ready
     User (192.168.0.130:(none)): anonymous
     331 Guest login ok, send ident as password.
     Password:
     530 Login incorrect - User has no home directory.
     Login failed.
     ftp>

For password I just hit Enter, later on I tried other ideas (guest, anonymous, etc) but none worked... I'd say that User has no home directory is indicative enough to suggest there's something wrong with mapping anonymous user with his homedirectory /vol/vol1/anonymous? Any thoughts?

Thanx!

How to measure NetApp network performance (iSCSI)

community@netapp.com — Wed, 04 Nov 2009 11:49:08 GMT

Hi,

Does anyone know the best way to monitor/view network performance with a filer (FAS2020) or where I should start looking for problems?

We have a FAS2020 running CIFs shares, iSCSI LUNs and NFS for our ESX infrastructure.

The filer and ESX servers are all connected to a pair of stacked gigabet 3750? Cisco switches and my network guy setup port channels for the filer.

We also seperate the iSCSI or VM kernel traffic into a seperate VLAN.

It's a fairly small deployment with 3 ESX servers, 30 virtual servers (not all using iSCSI LUNs - this is reserved for SQL & Exchange servers) and approx 150 users.

My problem is that iSCSI performance on the VMs with LUNs mapped seems quite bad. Copying files for example from the C:\ (VMDK file on the NFS vol) to the D:\ (iSCSI LUN) takes an age.

Also, if you map a iSCSI LUN from a normal PC/server and copy data to it, it also seems relatively slow. Whereas copying data to the normal CIFs shares is fine.

The CPU on the filers doesn't seem taxed, and I have checked the Cisco port channel ports on the filers and ESX servers (we use Orion NCM) - but they are at very low utlization.

Any ideas on how I go about looking for a problem or how I perform some tests to try & measure the iSCSI performance?

Thanks,

Marc

Why does NFS server (NetApp) return only "delete" access in Proc = reply?

Export entry on filer (v7.2.4)

/vol/agentvol/p6 -sec=sys,(ruleid=499),ro=thor14,rw=thor13,root=thor13:thor14,anon=65535

After I mount the above qtree using

and do a ls /p6, I get a permission denied error

snoop on the nfs traffic reveals that the filer is not sending read,lookup, modify,extend in the access

Netapp simulator 7.3 did not work

community@netapp.com — Thu, 04 Jun 2009 13:31:34 GMT

Hi folks, maybe I will find here a solution for my little problem.

I use following environment:

Lenovo Thinkpad T61 / 2GB RAM / Windows XP Professional SP2

Sun VirtualBox => Ubuntu-8.10-rc-desktop-i386.vdi

I have started Ubuntu and the wireless connection is working fine. With Firefox I checked the Internet access and it's working as well.

I have installed the sim and have started it, I can also login via console, but when I try to get access to the web appliance I got only "Failed to Connect" response.

Do the vol "minra" and "no_atime_update" apply in FC block Oracle environment ?

community@netapp.com — Fri, 20 Nov 2009 19:39:42 GMT

Hello all !!

Do the Flexvol options for minra and no_atime_update apply only to running Oracle on NFS from a Netapp, or do they still apply if you are presenting LUNs via FC to Oracle 10g (ASM) ?

Thanks

FlexClone and Reporting Database

community@netapp.com — Tue, 12 May 2009 10:28:53 GMT

Guys

Fairly new to NetApp and have a question

We have a reporting database for a production system where the database is currently built from a backup of the production database via unix scripts

Id like to replace that using ONTAP tools like FlexClone. However I have a few questions

Can a specific clone be rebuilt at a scheduled time? i.e. rebuild the clone from the production database every 6 hours. Clone keeps same name and no database config changes are required
Whats the impact on the production database during cloning? (Cpu etc)
During the cloning do we need to take the database down or can this happen without outage?
Am I thinking on the right lines here or would we better with something like SnapMirror to keep the 2 database in synch. Thought clones would be better as its a read only database but if we have to take the instance off line via some sort og syncrhonised scripts im wondering if its worth it

Any best practice would be nice!

Best Practices for CIFS homedir and group directory layouts?

community@netapp.com — Sat, 04 Apr 2009 16:51:09 GMT

I have a new FAS2050 filer and am in process of planning a migration of my employee base Windows based data from a Windows 2003 file server.

What I want to do is create a file structure that allows for a secure private home directory for each user with and Active Directory account which get automatically mapped at login, the same way it does for them presently.

Currently Home Folder path on the Profile tab in Active Directory Users and Computers, maps to \\WindowsServer\Users\username. This layout created a file structure where all users home directories are underneath that top level \Users folder andd required manually modifying the perrmissions on each user's home directory folder in order to lock it down.

What I would prefer is to have a home directory layout where each user home directory can be created under that top level folder where the permissions are automatically applied at the time the folder gets created via the Active Directory Profile tab. The only two people who should have full permissions on the user's home directory are the folder's owner, and the Domain Admins.

Can anyone point me at any Best Practices to make suggestions on the best way to lay out my directory structure?

Thanks!

SMO + DataGuard

community@netapp.com — Tue, 04 Aug 2009 14:54:15 GMT

Hi,

Found another thread that discussed overlaps and so between the different products but did not find a clear answer to my questions and thoughts.

I have a setup with a primary and a secondary datacenter with one Oracle server and one NetApp controller in each of them.

DataGuard is syncing data between the 2 datacenters

I have access to Protection Manager, I have SnapMirror and SnapVault licensed.

How do I create a smart backup setup in this environment?

Should I run SMO on both the primary and secondary DB servers with different retention policies?

Or just run SMO on the primary and let PM/SnapVault copy backups to the secondary DC and

not do anything on the DataGuard copy?

Any input is appreciated.

Thanks,

Erik Stjerna

Resetting and repurposing a FAS250

community@netapp.com — Thu, 12 Mar 2009 21:40:01 GMT

We have a FAS250 (Single Controller) which is currently serving CIFS shares and iSCSI LUNs for our XenServer cluster. I've now replaced this box with a better filer and so would love to repurpose it for our testing\dev environment.

The current setup is: 14x300GB FC 10k disks. 2 aggregates - agg0 (7 disks RAID4) and agg1 (6 disks RAID4) and a hot spare.

I'd like to reset the whole filer and create one aggregate with 13 disks - RAID-DP and a hot spare.

1. How do I reset the filer to run setup again?

2. Would there be any problems with the new setup I've specified?

3. The FAS250 has 2 NICs, does anyone know if it supports NIC teaming or iSCSI multipathing?

Thanks!

Questions on Hyper-V and iSCSI with a FAS2020

community@netapp.com — Wed, 01 Apr 2009 18:45:17 GMT

Please bear with my lack of in-depth knowledge of SAN workings. The story is that I'm going to be migrating from a StoreVault S500 (NetApp's small business line) to a FAS2020 in the coming weeks. On the StoreVault, I currently have a Hyper-V server running 6 VM's on a LUN. After skimming through some of these "best practices" docs from NetApp for virtualization, I'm getting overwhelmed. With the StoreVault, I didn't really have to worry about all this aggegrate and volume stuff. There was 1 aggregate and 1 volume, and then however many LUNs you wanted to create. Keep in mind that I'm a pretty small shop (5 physical servers, 6 VM's, Exchange with ~50 mailboxes). Questions I'm wondering in moving over to the FAS2020...

Do I need to worry about aggegates and volumes? I don't really know much about the differences and what to do with them. I'll also be moving over my Exchange LUNs (DB LUN and log LUN) with this migration as well as a ~350GB CIFS share. Do I create multiple aggegates or volumes for certain scenarios or something? If it's a performance thing, would it really matter for my small implementation?
Do I *need* SnapDrive to do LUNs with the FAS2020? I did not purchase SnapDrive with the FAS2020. I didn't even think about it since SnapDrive came free with my StoreVault stuff, but some of the best practices started talking about installing it for LUN stuff.

Are there any other things anybody can think of that may be drastically different moving over to this new system? Thanks!

NetApp CIFS Support DFSR?

community@netapp.com — Tue, 13 Jan 2009 19:01:06 GMT

Does the CIFS protocol on a NetApp FAS2000 support DFSR? I assume it support DFS, but I'm not sure about DFSR (Replicated) DFS. I know we can propose SnapMirror or other replication means, but customer is asking about DFSR in their environment. (This is pre-sales question from pre-sales engineer.) Customer desires to convert Windows File Servers to CIFS on NetApp and has a replicated DFSR environment.

SMSQL errors on initial configuration wizard setup

community@netapp.com — Wed, 15 Apr 2009 03:53:05 GMT

I'm guessing there's some obvious configuration step I'm missing here...probably on my mostly default SQL Server setup.

I'm receiving errors every time I try to run the configuration wizard script to migrate my databases from the local drives to the iSCSI luns. The error occurs after the pre-migration DBCC checkdb and the remapping of the system dbs. Then the config wizard script stops the sql server, and continually fails to restart the sql server services. At this point, it's unable to connect and fails with SQL-DMO authentication errors. I've checked my settings and can't seem to find anything wrong. This problem first occurred yesterday. Today, I uninstalled Snapmanager and SQL server 2005 from the machine. I then reinstalled both products. I left Snapdrive alone as it seemed to be working fine. SQL Server 2005 with sp3 is what I've been using.

Please help!

Note: SQL server services are using a domain user service account with no admin privs per MS best practices.

Snapdrive and SMSQL are using a domain administrator service account.

Difference between FAS 3140 A10 and FAS 3140 A20

community@netapp.com — Fri, 24 Oct 2008 20:21:45 GMT

I know the A10 has one controller and the A20 has dual controllers. The question is what are the advantages of using 2 A10's compared to using a single A20. Is every thing in the A20 Redundant? Any advice would be greatly appreciated.

Shelf firmware upgrade disruption

community@netapp.com — Thu, 05 Nov 2009 11:20:42 GMT

I wanted to check some things before we start upgrading firmware on a system.

System is a fabric metrocluster with combined ESH2 and ESH4 modules, so FC only.

I always thought ESH updates were non disruptive, but am confused by the documentation on this.

The upgrade guide for ONTAP 7311 states:

During

firmware updates to disk shelves controlled by ESH series modules or LRC modules, you do

not need to schedule system downtime for maintenance. The data on the disk shelves remains accessible

during the upgrade.

Further on it states:

By running the

storage download shelf command once, you upgrade all eligible modules

connected to both controllers in an active/active con

figuration. The command updates the modules

sequentially:

first all A modules, then all B modules. In addition, the process pauses I/O to all loops on

the controllers (both FCP and SATA).

Now both statements can be true, as long as I do a cluster failover during the upgrade of the shelf firmware. But really I'd rather not as this is a large environment with no guaranteers all connected servers have timeouts correctly set.

If I cannot use the manual method as it will pause all I/O to all shelves, I would need to do a cluster failover to initiate an upgrade I guess, is this correct?

A related question for another situation would be when we have FC-ATx modules in place with firmware 36 or lower, I read on this forum that not only would we have disruption for data on the SATA aggregate but also for FC aggregates (on seperate loops of course) because ONTAP would freeze all I/O on all loops during the upgrade. Is this true? It would be nice if the documentation could state this clearer.

Cannot delete folder on filer

community@netapp.com — Tue, 10 Nov 2009 02:49:20 GMT

Hi All,

A very good day to all of you. I have been trouble by this problem for a while. An empty folder in the filer that need to be deleted, no matter what, it cannot be deleted. the folder keep prompting that the folder is in use by a user or another program. But the actual facts is that there is no connection to the folders and the folder ACL has been removed, except the administrators.

Any suggestion for a solution to the problem will be most appreicated. Thank you.

SMVI - A general system error occurred: Protocol error from VMX

community@netapp.com — Thu, 13 Aug 2009 17:28:06 GMT

I have an smvi job scheduled daily that fails. I have attached the error log. It looks like SMVI attempts to create the VMware snapshot and fails due to a protocol error from VMX. Doing a quick search on VMWare forums states its a problem with a custom quiescing scripts http://communities.vmware.com/message/1016429#1016429- is this a problem with SMVI's script to trigger the VMWare snapshot?

As a side note I can manually create the VMWare snapshot. Also to note there are three smvi snapshots already in snapshot manager that look like they have never been committed. I have attached the .bmp file that shows this. I imagine it could be the error is being thrown due to the existing smvi snapshots present. Then my question is why is smvi not committing these snapshots?

Problems with CIFS / NTFS security settings

community@netapp.com — Tue, 04 Aug 2009 00:22:34 GMT

Im at a bit of a loss here, we have a new filer and are in the process of migrating all our existing windows shares into cifs shares, we have been using robo copy to do this for us to ensure all the existing NTFS permissions are carried across.

The setup is quite simple ... two root shares - GroupDrives / UserDrives both set for everyone to access, so that the single point of control is NTFS / ABE

UserGroupDirs /vol/UserGroupDirs                User Groups Share
             ... access based enum supported
                        everyone / Full Control
UserHomeDirs /vol/UserHomeDirs                 User Home Drives Share
             ... access based enum supported
                        everyone / Full Control

NTFS security on both shares is the same

- Domain Admins - Full - This folder, subfolders and files

- Domain Users - Read - This folder only

- File Share Admins - Modify - This folder, subfolders and files

- Helpdesk Admins - Modify - This folder, subfolders and files

Security was added to the shares through computer management before the migration began, and we have had no major issues until now.

Here is where the issues start:

- The checkbox for 'Allow inheritable permissions ...' is unticked and if checked and applied, the settings do not stick.

- Under the UserHomeDirs share i have another folder shared for terminal services profiles, existing user content is present, but windows will no longer auto create profiles in it as it gives a permission denied error 'does not have access to the resource' during logon for new users. The user account does have access and can create folders manually.

- We have an AS/400 using a QNTC service account in our AD to access our windows shares, it is a member of domain admins, so should have complete access to the filer (domain admins are also a member of the admins group on the filer) Yet when browsing it can only see the UserHomeDirs share, it cannot see the UserGroupDirs share at all and we have a number of scheduled jobs that drop content in folders under the root share which do not work.

In my haste i have made the error of adding the QNTC account to the NTFS permissions on the root of the UserGroupDirs, simply to give it read only access to the top level share (although it is a member of domain admins and domain admins already has full access) and that has been applying for the last 45 minutes, and for some other reason now the read only box is checked and greyed out, but i can uncheck it (is this because the other security settings are still being applied?)

Any thoughts would be greatly appreciated

Cheers - Ben

Newbie question..how do I run perfstat ?

community@netapp.com — Fri, 13 Mar 2009 18:08:26 GMT

I am trying to gather stats on CIFs operations during our peak load.

How exactly do I run perfstat?

Do I need to ssh in to the filer?

What options should I be passing the command?

Rigth now when i ssh in and just type in perfstat, it says:

nfs tuning for 1G/sec load

community@netapp.com — Tue, 02 Jun 2009 13:17:00 GMT

Hi All,

we are running FAS3040 with OnTap 7.3.1.1 (nfs license only)

one of our volumes has a write throuput of 90-100M per sec. we also using multimode vif to get a network bandwitch of 2GB and a PAM card .

this volume has the vol options no_atime_update set to off and the general option nfs.tcp.recvwindowsize set to 262144.

the NFS clients are running Solaris 10 and are mounting using NFS v.3 (tcp) .

is there something else we can do to tune the NFS performance? also does OnTap support the Nagle algorythm on the tcp stack?

Regards

David.

NetBackup with Simulator

community@netapp.com — Tue, 24 Mar 2009 05:05:27 GMT

Hi,

ONTAP 7.3 simulator has 4 tape drives available. While integrating these with NetBackup 6.5, i am able to view the drives by issuing

set_ndmp_attr command, however, the Netbackup software does not detect the drives on scanning the filer.

Please suggest if you have any answers.

Backing up Exchange 2007 on a netapp

community@netapp.com — Fri, 02 Oct 2009 16:52:29 GMT

Currently we're running Exchange 2007 on a 2 node cluster

with all the databases on our netapp filer. We're backing up the Exchange servers using Commvault and snapping the databases hourly with the Netapp.

Once a day were backing up the snaps using a Commvault NDMP.

What would be the recommended why to backup my exchange environment?

Is our current backup strategy effective or flawed in a way we haven't thought of yet?

Is there a writeup on how Provisioning/Protection Manager selects the "best" resource within a resource pool?

community@netapp.com — Sat, 14 Nov 2009 16:16:15 GMT

I've been looking for a writeup that documents how Provisioning Manager / Protection Manager selects the "best" resource (filer / aggregate) to use within a resource pool.

Example: The customer would like to provision new storage via Provisioning Manager. They've set up their Provisioning Policies, and their Dataset. They're selecting to Provision via the GUI, using the following Resource pool makeup:

Primary_pool:
Filer1
Filer2
Controllers: Filer1 & Filer2 have the following makeup:
Filer1
aggr1 - 50% full
aggr2 - 20% full
aggr3 - 70% full
Filer2
aggr1 - 45% full
aggr2 - 80% full
aggr3 - 10% full
Assume that all the aggregates are the same configuration and the same overall size.

When the customer selects to provision another "chunk" of storage (amounts to 10%) aggr capacity.... which Aggregate within the resource pool will be selected and why?

Auditing netapps

community@netapp.com — Thu, 08 May 2008 07:15:53 GMT

Hi,

I configured my netapps to be able to audit access of files with the following commands

options cifs.audit.enable on

options cifs.audit.autosave.ontime.enable on

options cifs.audit.autosave.onsize.enable on

options cifs.audit.liveview.enable on

options cifs.audit.logsize 52428800

options cifs.audit.autosave.onsize.threshold 50m

options cifs.audit.autosave.ontime.interval 20m

my aim was to have external log files (.evt) with size of 50 MB or each 20 minuts. i tried many times but always the result is files with size almost 500 KB and it is generated each 11 to 20 seconds.

as you know if i want to manage number of these log files i have the ability to 999 files only which is not available with this small size of the file becuase in one day i got more than 2000 log files.

so is there a mistake or missing commands?

SMMOSS v2 release dates

community@netapp.com — Thu, 12 Nov 2009 10:39:53 GMT

Does anyone know what date the latest version (v2.0.2?) of SMMOSS v2 was released? Also, if anyone has the dates of previous releases that would be very useful e.g. v2.0R1.

Thanks,

IOPS for SATA/SAS/FC disks

community@netapp.com — Tue, 15 Sep 2009 09:40:53 GMT

Can anyone tell me what's NetApps stated performance of IOPS on SATA/SAS and FC disks?

After a general idea as realise any answer can be driven by different factors (i.e head type, aggregate setup, application type etc)

Help Migrating Data from Filer to Win Server

community@netapp.com — Wed, 04 Nov 2009 13:09:04 GMT

All,

I'm hoping someone out there can help me out with this. Let me start by saying that I know nothing about NetApp filers. Nada. I have been tasked with migrating data off of an organizations Filer and onto a Windows 2003 file server so that the NetApp can be reconfigured. Our organization does not support NetApp, and this group decided to buy one without any foresight into how it should be used correctly, backed up, or even operated at a basic level. The guy who purchased / implemented it has left the organization, so nobody here is much help with this task.

Here's what I know:

- Filer is a NetApp F800 series.

- Configured as CIFS, and user data is being redirected to shares on the Filer.

- They have no way to backup the data on the Filer.

- The Filer needs to be reconfigured to present as volumes attached to a server in order to be protected by our current backup solution.

Is there a way to move that data off of the Filer using the Filer itself / DataONTAP. I need to move all of that data to a shared folder on a Win2k3 file server and redirect users to the new location. Redirecting the users isn't a problem, but getting it off the filer all in one shot is the problem.

I don't mean to sound like an idiot here, but this is just not my area. I know that this isn't a lot of information on the setup we've got, but I don't know jack about it, but I can provide more if needed. Just tell me where to look. Nobody knows anything about their own piece of hardware here, so I'm really flying blind. Any assistance would be greatly appreciated.

Thanks in advance,

Chris

File Count Limits for NSA Volumes

lamarca@netapp.com — Fri, 20 Nov 2009 15:16:05 GMT

There is an older document on the NOW site referencing high file counts (https://fieldportal.netapp.com/exLink.asp?16808049OF26L27I57212228) for Data OnTap 6.x. Do we have an updated one for OnTap 7.x and 8.x for NAS shares? I am having issues finding anything newer to reference for a partner.

Thanks in advance for the information.

SMVI time out errors and quiesce error

community@netapp.com — Sat, 11 Apr 2009 15:25:40 GMT

Hi guys

I am quite new to the Netapp world, but still very happy for the gear :-)

We have a metro cluster with 2 FAS 3160 boxes, and on top of that 20 blades running Vmware ESX, and a total of about 220 virtual machines.

We really like the SMVI product, it is very nice to do backups in under 1 hour..

BUT, we havent yet made a complette error-free backup, everyday we se some machines not being backed up becauce of either a "Operation timed out" or a "Creating a quiesced snapshot failed because the create snapshot opreration exceeded the time linit for holding off I/O in the frozen virtual machine"..

Until now we have:

The latest host utils, 5_0R2 on all ESX boxes

The lastest ESX version, update 4, 3.5.0 153875

The latest vmtools on all vm machines

The latest vCenter, 2.5.0 u4

SMVI 1.0.1R1

Set the disk time out reg.key on all the vm's to 120 sec., although I have seen some mention that it should be 190 secs?

(HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Disk)

TimeOut Value 120

We are only using VMFS datastores, and FC.

The strange thing is that the machines that failed last backup probally will succed next time, but then others will fail..

Can anyone please help me with further tips om troubleshooting this, or is this the real world, and I must live with some machines failing?

-tonigh we try to do the backup without the "Vmware consistency snapshot" option enabled..but we would veru much like that feature enabled..

Thanks.

Best regards

MBRALIGN 64K Blocks

community@netapp.com — Fri, 15 May 2009 16:21:53 GMT

I am trying to align to a 64K block size with MBRALIGN and it only uses the default of 8K

Am I doing something wrong with the command line or is there something more I need to do on the VM?

When I run ( mbralign --preview --bs=64 BlockTest.vmdk ) it shows it will do a 64k block.

This is the command line I am using.

mbralign --bs=64 BlockTest.vmdk

Snapvault - creating a snapshot manually

community@netapp.com — Wed, 06 May 2009 19:33:01 GMT

Hi folks,

I'm busy setting up Snapvault for the first time.

A number of applications are configured to take snapshots of their volumes manually rather than the filer doing them (via snap sched). These work similar to SnapManager in that they need to make the data crash-consistent before taking the snapshot.

I need to start storing archived copies of these snapshots in a Snapvault secondary. So, I created a Snapvault relationship between the primary qtree and a secondary volume. This all works fine - a baseline copy took place and snapshots were created on both the primary and the secondary. I can successfully issue a "snapvault update" on the secondary to have it copy the deltas from the primary.

What I can't seem to get to work - on the primary or the secondary - is manually creating a snapshot using "snapvault snap create". As far as I can tell the syntax should be "snapvault snap create <volname> <snapname>" but whatever combinations I put for <volname> and <snapname> on the primary or the secondary, I get the following error:

Snapshot creation aborted: snapshot target not configured.

I cannot find any references to examples that may be useful to me. It seems that I'm missing something, possibly something obvious.

Any help would be appreciated!

Cheers,

Richard

ONTAP 8: FPolicy and 3rd party software

community@netapp.com — Thu, 19 Nov 2009 08:35:58 GMT

Hello there,

we are planning to implement a HSM mechanism to migrate files from a NetApp system to other places. In cas a migrated file is accessed, we are using the FPolicy mechanism to move the file back to the NetApp storage. Since ONTAP 8.0 supports onboard antivirus software (Sophos and Trend), we are wondering if and how FPolicy is influenced of this. Is there any way to detect (and to prevent) FPolicy notifications if a certain 3rd party software (virus scanners, backup software, ...) is accessing a file?

I'm looking forward to your answers.

Adding disks to an aggregate

community@netapp.com — Tue, 10 Feb 2009 06:46:38 GMT

What are the steps, in general terms, for adding disks to an existing aggregate? I wish to add to performance, so my understanding is some sort of "re-striping" would be necessary to properly re-allocate the extra space?

Thanks!

Storage Capacity vs Physical space don't match

Ontap Virtual Simulator VM

community@netapp.com — Wed, 12 Mar 2008 19:28:02 GMT

In the past I've setup the simulator to test features, which work great, however it still takes some knowledge of Linux and Ontap to get it up...

I now have a Vmware ESX Linux VM with the ontap simulator running on it which works great. Now every time I need to test an ontap feature, I don't have to spend a day installing the simulator... And when I screwup the Ontap configuration, I use VM snapshots to roll back the configuration

It would be great if Netapp built a VMware appliance with Ontap running natively on it and published it to the Vmware Applance Marketplace.

Not only would this be a great testing VM, if it were polished up, the VM would be an instant hit with customers wanting to take a quick look at Ontap...

And I bet it would win some of the vmware appliance awards!

And it would be very interesting if Netapp allowed this VM to compete with the openfiler community!!

How to add a Tape device to a FAS6040

community@netapp.com — Sun, 24 May 2009 23:48:11 GMT

Hey guys, I've been trying to find some documentation on how to attach a tape device to a FAS6040 as I want to do ndmp backups.

I know I have to zone it to the Fibre port and then set the port into an initiator port, but I do not know the commands on the netapp side of things.

Any feedback would be helpful.

iSCSI service shutdown after reboot

community@netapp.com — Sat, 07 Nov 2009 15:28:20 GMT

Hello, all!

I've a bit a puzzle here regarding iSCSI services. Namely, when rebooted, one of our systems tried to start iSCSI automatically - as it should - but the very next second it, the service was stopped. Here's the Autosupport segment describing it:

Sat Nov 7 15:28:12 CET [dfu.firmwareUpToDate:info]: Firmware is up-to-date on all disk drives
Sat Nov 7 15:28:12 CET [sfu.firmwareUpToDate:info]: Firmware is up-to-date on all disk shelves.

Needles to say, none of the servers couldn't establish iSCSI connections. Any thoughts on what might've caused this?

Thanks,

Migrate Data to NetApp (CIFS)

Installing a Simulator

badoem@willis.com — Wed, 08 Jul 2009 00:47:16 GMT

Hi all

I am trying to run the netapp simulator in Ubuntu 8.10. However I'm unable to proceed past "bash setup.sh -z". I keep getting "bash: setup.sh: No such File or Directory". I tried using "../setup.sh" but still no joy.

I have struggled to understand why its doing this and as I am a brand new novice at the is Linux lark, I'm not sure where else to look. Please please please someone please help as I've got my NS0-163 exams coming up in a couple of weeks.

Prot Mgr 3.8 - name for snapshot copies

community@netapp.com — Wed, 08 Jul 2009 13:51:05 GMT

With Prot Mgr 3.8, the name for the local snapshot copies includes a timestamp. Having a timestamp in the name for the snapshot copies is kind of unwielding. Plus, it is kind of redundant as there is already a "date" column in the output of "snap list". Is there an alternative to the timestamp? In which case, is there a way to remove the timestamp from the snapshot name?

Another SMSQL question regarding "retainsnapofsnapinfo".

community@netapp.com — Wed, 01 Jul 2009 16:31:45 GMT

A quick question which I hope someone can help me with.

I using SMSQL & running daily FULL backups at 00:00 every day and 18x hourly tlog only backups.

I want to keep backups going back 4 days.

Therefore I have 2 separate SMSQL jobs scheduled: 1 for the FULL backups (which include Tlogs also) and 1 for the hourly tlog only backups.

The SQL job params look like this:

TLogs params: -RetainBackupDays 4 -lgbkonly -bksif -RetainSnapofSnapInfoDays 4 -trlog -noutm –mgmt standard

Full backup params: -RetainBackupDays 4 -lb -bksif -RetainSnapofSnapInfoDays 4 -trlog -noutm –mgmt daily

Now:

- By default a backup also forces a "snapshot of the snapinfo LUN" - this means that after every backup (whether it be a tlog or full) the vol holding the snapinfo LUN is snapshot! Is there a better way to configure this? Maybe only do volume level snapinfo snapshots once per day i.e. when my full backup runs & not after every tlog backup?

My problem is that the SnapIno LUN always has plenty of space and can hold 4 days of SQL backups no problems - but the volume snapshots didn't seem to get deleted when I was using the default "-RetainSnapofSnapInfo 8" command (it wasn't keeping only the last 8 - it was keeping more than 10days worth which eventually filled my volume). When this happens SMSQL doesn't generate an error as the backup worked - only the snapshot of the vol failed. Instead I get a Filer volume warning telling me my volume is 100% full.

The only option in SMSQL is to either turn "create snapshot of snapinfo drive after backup" on or off - which means after every hourly transaction log backup it also snapshots the snapinfo drive. Is this not overkill? I have 4 days of streamed backups on the LUN, then can I simply keep 1 day of snapinfo snapshots?? Why are the snapinfo snaps so important if we have the backups available on the LUN anyway?

I've read a great post about FR and SMSQL, but I can't find much regarding this "-RetainSnapofSnapInfo" and how it should be used when performing regular SMSQL backups.

Thanks,

Marc

Progress DB on UNIX?

community@netapp.com — Wed, 18 Mar 2009 19:59:44 GMT

Hi!

IHAC who has some Progress DB instances running on AIX and FCP on NetApp LUNs.

He would love to use our SnapShot technology for Backups of this LUNs but we do not provide any SnapManager for this. Even our nice (internal) SnapCreator Tool cannot handle Progress DBs.

Do you know any customer or internal colleague who could have experiences in scripting something like this??

Kind regards,

Alert upon reaching 80% volume space utilization

community@netapp.com — Fri, 03 Jul 2009 03:22:04 GMT

Hi,

I am new here, please understand if i am on the wrong place posting my concern.

And this is my concern, i have a LUN and it is 50GB of space residing on a volume with 50GB usable space. The space guarantee of the volume was set to volume. The LUN does not have space reserve. The LUN is mapped on a SQL server and function as repository of the Database Log. There was a time that the LUN was offline due to lack of sapce on the volume. I increased the size of the volume as well as the LUN size and put the LUN on online state again. I don't want to encounter the same problem again and I'm thinking if there is a possibility that the filer will alert me if the volume reaching 80% space utilization?

Thanks.

The filer has Data ONTAP 7.3.1 installed.

Storage Provisioning with Protection Manager

community@netapp.com — Tue, 30 Jun 2009 10:12:39 GMT

Hi Everyone,

we are using Protection Mananger to perform SnapVault backups.
On the secondary site we have 1 resource rool with 7 aggregates.
When an aggregate is full or nearly full, Protection Manager wants to migrate a SnapVault destination from
one aggregate to another (more free) aggregate.
But this operation fails.

My question is:
Do we need an extra Provisioning Manager license or which option enables this feature?
Or is it an other problem?

dedupe causes vol size to grow

sarbjit@netapp.com — Thu, 25 Jun 2009 15:14:01 GMT

IHAC who are using FAS3020 running ONTAP 7.2.5.1.They enabled dedupe on a volume of 30GBwhich is not space reserved and the fractional reserve is set to 100%.The volume has a LUN of 25GB.

After enabling dedupe,customer saw the volume size increasing and it reached to a max autogrow limit of 60GB.Customer then disabled dedupe.(I believe they did using sis stop/sis off commands which saves the current fingerprint information) as the aggregate was also running out of space.

How can we reclaim the grown space in the volume?Is it because of the fingerprint information & checkpoints?can we delete the fingerprints and start a fresh dedupe using "sis start -s"

Do a deletion of fingerprints and "sis undo" the volume first before starting it all over.

Any inputs will be highly appreciated.

Max number of files

community@netapp.com — Sat, 18 Oct 2008 14:32:37 GMT

I have a FAS3020 with 1Tb volume used as storage for an application that generates millions of small files - 30-40k each.

We have been getting an error message saying files are too large which we assume to mean there are too many.

We have increased to maximum number of files allowed as the volume is not full.

My questions:

1. How does ONTAP calculate the max number of files for a given volume size?

2. How many files can be added per volume above the default setting before you start to see an impact on performance?

3. How does having so many files affect performance when trying to do a backup?

4. Is there a best practice for data set containing millions of small files?

Thanks

Rod.

What is the Cloud?

ckranz@b2net.co.uk — Mon, 27 Apr 2009 23:52:12 GMT

I've been having a few conversations with various different people over the past few months about the Cloud phenomenon that is currently sweeping the industry, and it's an interesting term and concept. It seems nicely packaged up by a lot of service providers and outsourcing agencies, but it is a lot more than that.

I see the Cloud as stepping up from DR and BURA and move into fully automated Business Continuity. This has nothing to do with external service providers or outsourcing the IT infrastructure, this has to do with how the whole business works. Again, this is more than just keeping the data and systems running. I have a lot of customers that go to a lot of effort to put in a very reliable and proven DR infrastructure, but they have no-where for their employees to work from!

I wanted to post this here as a general open question. What does Cloud Computing and various Cloud terms mean to people out there in the real world? Is anyone seriously looking into it? There's been a lot of press coverage of Cloud systems that have had catastrophic failures, so is it really something to trust and put all your faith into? Is it just a buzz word and a good marketting term in our current economy? Is there anything that NetApp Engineering could possibly give insight into what NetApp could offer as Cloud services at the storage level?

Open to any sort of input or discussion here, so please post your thoughts!

Ethernet/IP High-Availability

community@netapp.com — Tue, 10 Nov 2009 17:44:59 GMT

I'm focused on configuring Ontap providing CIFS, NFS, and iSCSI services to survive various Ethernet/IP pathologies, in data centers equipped with dual Ethernet switches. (Head-b not shown)

I've found it easy enough to configure SVIFs to survive loss of link, which I test by administratively disabling ports on the Ethernet switches (or by yanking Cat6 cables).

But that's a low bar over which to hop. The pathology I want to solve is the case in which the "Lights are on, but no one is home", i.e. the switch is transmitting Ethernet link pulse but isn't forwarding frames. This occurs under a range of scenarios, including (a) a switch administrator fat-fingers a VLAN assignment, (b) the management blade in the switch fries, (c) the switch reboots. [I've been testing this scenario using (a) -- I assign one or more ports to an isolated VLAN (VLAN1).]

I can see the NICs emitting ARP broadcasts (every five seconds) for the IP address of the SVIF to which they belong -- this looks like 'heartbeat' behavior to me. But my configuration still doesn't survive loss of a port. If I assign, say, Port1 to the isolated VLAN, then pings to both SVIF1 (10.11.42.101) and SVIF2 (10.11.42.102) fail. I'm guessing that I'm seeing two effects here:

(a) The heartbeat algorithm hears both NICs reporting that they cannot see the other NIC's heartbeat, and it doesn't know which NIC is still functional (e0a in this example) and which is crippled (e1b in this example). So it continues to use both NICs.

(b) The path to the default route gets bound through SVIF1 in this example, so that when ICMP Echos arrive on SVIF2, the ICMP Replies are emitted out SVIF1 ... and, specifically, out e1b ... the frames reach the Ethernet switch, where they are dropped, on account of the VLAN isolation

My questions here:

(1) Does the heartbeat algorithm function more effectively if I create SVIFs composed of an odd number of NICs (e.g. three)? i.e. is there are quorum component to the algorithm which determines whether or not a NIC should remain an active member of an SVIF?

(2) Does the algorithm which determines whether or not to deactivate a NIC take into account the packet receive buffers on the NIC? i.e. if they are incrementing, then the NIC is likely connected to a functioning Ethernet/IP path; if the counters are not incrementing (or not incrementing rapidly), then the NIC is likely isolated.

(3) Is there a way to 'bind' the path to the default router to SVIFs? Something like:

route add default 10.111.42.1 svif1 10

route add default 10.111.42.1 svif2 20

I think the answer is 'no' ... I've tried ... but I ask in order to illustrate the character of the problem I'm trying to solve.

So then I read about Dynamic Multimode VIFs, and second-level VIFs.

I'm not confident that this approach survives the "Lights are on; nobody is home" situation -- it seems to me that the algorithm listening to the ARP heartbeats would still have trouble figuring out when the management card in, say, c6k-a-switch had fried. [Though perhaps LACP Hellos would quit, in that scenario, and Ontap would then deactivate e1b and e0a.]

Perhaps I would be better off accepting a head-failover when a switch fails, lose my CIFS clients, and quit trying to straddle the two switches.

Anyway, before I continued down these paths, I figured I'd ask for input. Presumably, other people have invented this wheel already. How do you harden a multi-protocol Ontap box against the "Lights are on; no one is home" effect?

BTW: I'm using a V3170 running 7.3.1.1 as my test bed.

Restart CommVault NDMP backup job

community@netapp.com — Fri, 03 Jul 2009 09:15:08 GMT

Can anyone tell me how to restart a failed CommVault v7 backup job?

I have a tape library connected to a FAS3070 via SCSI and have managed to write 3 Tb to tape when a network error between the filer and CommVault management agent killed the job. CommVault has restarted the job from the begining again but the filer has shows the snaphot as (busy, backup, dump) and backup status as

ID     State     Type Device   Start Date   Level Path
-- ----------- ---- ------ ------------ ----- ---------------
0 RESTARTABLE NDMP          Jul 01 15:05    0    /vol/dmfil01wsf/
1 ACTIVE       NDMP ndmp    Jul 02 17:35    0    /vol/dmfil01wsf/

I know how to terminate the job on the filer but would like to continue from the point of failure if posible.

Is it possible to change the default system SERIAL number 987654-32-0 in Netapp simulator ? (I know how to change the system ID)

community@netapp.com — Wed, 14 Jan 2009 09:58:36 GMT

I have installed two Ontap 7.2.1 simulators called sim1 and sim2 on one RedHat Linux Ent 4 server but both simulators list the same SYSTEM serial number (the sysconfig command confirms that both use System Serial Number: 987654-32-0)

I need to demonstrate customers the use of the Veritas Storage Foundation Suite for Windows (SFW) DMP DSM multipathing option for servers that are attached via ISCSI to TWO different Netapp Filers. SFW lists unfortunately the disks from both sim1 and sim2 under the same array/filer name = 'NETAPP LUN 987654-32-0' . SFW does not use the System ID or ISCSI Target ID to identify different Netapp Filers but the System Serial Number. My demonstration will not work when both virtual netapp filers have the same system serial number as I want to demonstrate different array settings for each array which cannot be done if both filers are shown as one array/filer.

I need in total only two different System Serial Number (one for each of the two simulators).

Note:

a) I know that you can change the System ID by editing the ,serialno file but I can't find this option for the System Serial number.

b) I have also assigned a different ISCSI target ID to each simulated Netapp filer.

c) I believe the System serial number has been hardcoded by Netapp in the maytag.L.

Is there anything that can be done to change it?

Thank you very much for your help!

Bosch and NetApp Partner to Provide Customers with Proven Storage Solutions for IP Video Surveillance

summersj@netapp.com — Wed, 18 Jun 2008 22:27:06 GMT

Bosch Security Systems and NetApp, Inc. (NASDAQ: NTAP), have formed a strategic, global partnership to capitalize on the rapid development of the IP video surveillance market. Under terms of the agreement, Bosch will sell and support cobranded NetApp® storage devices as part of its closed-circuit television (CCTV) portfolio.

“The market is continuing to mature in its understanding of IP video system architectures, resulting in a substantial up-tick in the adoption of Bosch’s approach for recording video-streaming video direct to a RAID array or storage area network and eliminating network video recorders,” said Johan Jubbega, vice president of Global Video Systems and Products, Bosch Security Systems, Inc. “The partnership with NetApp will increase the options we offer our customers by adding proven technology from a leading storage solution provider. These products will appeal to systems integrators and our newest generation of customers-IT-savvy end users.”

Bosch pioneered the development of IP cameras and encoders that stream directly to RAID arrays or storage area networks (SANs). This award-winning, efficient approach to video recording is made possible with the use of an IP-based storage standard-the Internet Small Computer System Interface (iSCSI). With the partnership agreement, Bosch is growing its portfolio of storage devices that use the iSCSI protocol as the company will resell four cobranded NetApp products or solutions.

The NetApp products offered by Bosch include the FAS2000 series along with the S550 and S300, providing a cost-effective family of products that delivers enterprise-level performance and scalability with a storage density ranging from 2 to 104 terabytes. Both the S family and the

FAS2000 Series were recent winners of the ServerWatch Product Excellence Awards and will serve as important components of Bosch video surveillance solutions for a wide range of applications.

"With the desire growing among customers for IP video surveillance solutions, the timing is right to partner with Bosch,” said Andreas König, general manager and senior vice president EMEA for NetApp. “By leveraging NetApp solutions that utilize the iSCSI protocol combined with Bosch security products, customers are provided with a proven and effective answer to their video surveillance needs."

Under terms of the partnership, NetApp will assist Bosch associates with presales support for the cobranded products. The company will also deliver training and certification to Bosch technical support groups. As a NetApp authorized provider, Bosch will provide customers with postsale technical support for the storage devices. This level of integration will provide a streamlined experience for customers during and after the sale of the cobranded products.

To maintain continued compatibility of products, Bosch will also gain ongoing insight into NetApp’s technology roadmap. Early access to NetApp’s devices will assist Bosch in tuning its video surveillance products to take advantage of new features and functionality in NetApp’s future storage offerings.

Performance Acceleration Module (PAM) Intelligent Caching

community@netapp.com — Thu, 11 Sep 2008 23:43:58 GMT

Performance Acceleration Module (PAM), an intelligent caching device that can significantly enhance the performance of applications that do a lot of disk-intensive random reads. A recent Tech OnTap article describes both PAM hardware and software including the caching strategies it uses. We go on to introduce Predictive Cache Statistics (PCS) a software tool that can help you determine if your storage systems can benefit from PAM, how much cache you'll need, and how to best configure it.

Check out the article at: http://www.netapp.com/us/communities/tech-ontap/pam.html ... I recently presented on this topic in a Tech OnTap Live User Group so if you're really interested you can also check out the presentation and event recap.

What are your biggest performance concerns? What do you think of PAM? What do you want to know more about?

FAS2020 Delay

community@netapp.com — Tue, 07 Apr 2009 17:52:41 GMT

Hi all, I am new to NetApp and have just set up a FAS2020 on our network.

We're experiencing a 5 to 10 delay when opening Office files from Windows 2003 servers when we access the share as a UNC patch.

If we access the share using the fas2020 IP address, there is no delay. This seems to be a name resolution issue.

We've checked DNS, WINS, etc and everything seems to set up right on the FAS and the Windows 2003 servers. Accessing Windows server shares experience no delays either. What else could be wrong?

TIA.

Hector.

No CIFS access although security permission for everyone is setting full

community@netapp.com — Sat, 18 Jul 2009 16:14:21 GMT

Hey Techis,

I have a problem with a cifs share.

I copied data from a unix security style qtree to a volume at a second filer which security style is NTFS only. We are working in a clean windows environment. So I created a CIFS share for that folder and Windows User everyone has full access like it is the standard method for a new share.

I can browse to some folders normally. But at some folders and subfolders I get an access denied. In the security options of the root folder I activated booth checks to replace the permissions in all subdirs.

But although I cant access the aforesaid folders.

With NetApp System Manager I can correctly browse to all folders when I wanna create an new share.

Hope you can follow my problem and my improvable English

Any ideas?

FPolicy, FP_ScreenRequest2 & setattr problem

community@netapp.com — Thu, 17 Sep 2009 11:09:08 GMT

Hi, Guys

I am developing an fpolicy-server to track user activity; one of the activities I want to track is access control changes. As FPolicy SDK 7.3 guide states, this is possible through setattr request.

So, when I start my fpolicy-server, I (remotely through ontapi apis) create, configure and enable policy, and then register as fpolicy-server. The problem is when I specify “setattr=true” in additional parameters upon registering with FP_Registration, filer says that this parameter is invalid and ignores.

So that, right now I didn’t receive notifications with FS_OP_SETATTR in clientop. What may be wrong? Any suggestions are greatly appreciated.

P. S. I use simulator 7.3 and 7.3.1 as test lab.

P. P. S. My fserver serves request through FP_ScreenRequest2

P. P. P. S. Here is output from simulator console upon fserver registration, and from fpolicy command just after the registration is finished:

Thu Sep 17 15:02:23 MSD [fpolicy.enable:info]: FPOLICY: The file policy feature has been enabled.

Thu Sep 17 15:02:24 MSD [fpolicy.fscreen.enable:info]: FPOLICY: File policy quest_itfa_netapp_policy (file screening) is enabled.

"Access is denied" when writing to filer from windows host

community@netapp.com — Thu, 18 Sep 2008 11:15:57 GMT

Hi,

Since one month I am faacing "Access is denied" errors when a large number of files are copied from the local disk of a windows 2000/windows 2003 server to a filer partition. I use the MKS tool kit mv command. However, I later realized that this issue is present even if I use the windows copy/xcopy commands to copy the files.

This error comes even for a small file.

Have you faced this issue and what was the solution?The sysadmins have updated me that there is no issue on the filer side.But I too have not made any changes on the windows machine environment.

The error comes randomly for different files and the number of such errors varies each time I initiate a copy/mv..

Your help will be highly appreciated.Please let me know if you need additional information on this issue.

Thanks,

Bala

Do IOPS on Aggregate Performance Report include IO from cache Hits?

community@netapp.com — Tue, 20 Oct 2009 16:11:05 GMT

Hi - I'm looking to find (for each aggregate in a FAS3070 Filer) how many IOPS are being delivered at peak.

I'm working on the theory that each data disk should be capable of delivering approx 180 IOPS (they're 15k FC disks), hence I can create a "theoretical" performance limit for each aggregate, (180 x number of data disks), beyond which latency is likely to suffer.

The reason I want to know is that we are considering moving to 300GB disks, but there is little point in getting extra capacity if I can't practically make use of it (I get double the capacity but I get no more performance).

My storage admnistrator has produced an Operations Manager aggregate report (OPS Manager – ‘dfm report view aggregates-performance-summary’) showing at peak a level of IOPS that would equate to approx 600 IOPS per data disk.

600 IOPS per disk doesn't sound realistic (nobody is complaining of poor latency/performance)

Could it be that the aggregate performance report is including IOPS from Cache Hits??? (In which case this is the wrong report for me - I am purely interested in Disk IOPS).

Can anyone help?

Stu

P.S. Summary below:

Filer Name	Aggregate	# Data Disks	Theoretical IOPS maximum	Monitored IOPS	% utilised
Filer1	aggr1	70	12601	10748	85%
Filer2	aggr1	68	12241	8841	72%
Filer3	aggrebg	47	8461	10239	121%
Filer4	aggr1	37	6661	21168	318%

Unused interfaces alerting for status down

community@netapp.com — Tue, 16 Jun 2009 14:31:12 GMT

Hi,

I have a query, as soon as a filer is added to the DFM host, it does generates an alert for all the unused interfaces saying “Interface Status down” during a initial scan. Is there a way/option in DFM by which we can suppress such alerts as it's creating a lot of unnecessary events in our environment.

I currently use SME in my Exchange environment. Do you have a solution for single item recovery?

community@netapp.com — Sun, 09 Mar 2008 09:25:46 GMT

NetApp Single Mailbox Recovery, or SMBR for short, is our single item recovery solution. Using SME created backup sets, you can mount the LUN within a Snapshot copy that contains the Exchange database that you want to recover mail items from. You would also mount the LUN that contains the transaction logs for that same backup set. Once mounted, you'd start SMBR, point to the locations for the database and transaction logs and recover mail items by literally dragging and dropping them back into a user's mailbox.

You have several options when using SMBR. You can recover items from:

Exchange database
A pst file
A content analysis store

And once the items that you're looking for are found, you can place them:

Into the user's mailbox live on the Exchange server
Into a pst for archiving
A content analysis store for further analysis

SMBR also includes new advanced search capabilities to make it much easier for an Exchange administrator to find items they're looking for. The new functionality allows you to specify keywords, dates, search within attachments, all to make it easier to located the desired mail items.

VMware SRM and NFS Datastores

community@netapp.com — Wed, 14 Jan 2009 18:56:22 GMT

OnTap SDK 3.0 Win32 API FindFirstFile() & FindNextFile() Bug

community@netapp.com — Tue, 06 May 2008 15:37:06 GMT

I am using latest manage-ontap-sdk-3 dated March 26, 2008, Windows XP Service Pack 2, Visual Studio 2005.

</div>

<div>

I am using FAS250 with version "NetApp Release 7.1.2.1: Sun Mar 18 20:52:21 PDT 2007" as well as version

</div>

<div>

"NetApp Release 7.3X9: Fri Nov 23 23:46:25 PST 2007"

</div>

I found there is a problem with the Win32 calls:

FindFirstFile() & FindNextFile()

The problems occur as follows:

1.if filer has folder 3 folders, the Win32 call will only return 2 folders

2.if filer has folder 2 folders, the Win32 call will only return 1 folder

2.if filer has folder 1 folder, the Win32 call will only return 0 folder

That implies the Win32 call will only return 1 foler less.

If I use the Windows server (CIFS) with the same codes, I will consistently get all folders. So I can conclude that Ontap is doing something different than Windows servers. Could anybody help me out with this issue?

Thanks.

Custom Thresholds for "Inodes Almost Full" DFM Alerts

community@netapp.com — Tue, 18 Aug 2009 20:20:37 GMT

I am currently using DFM/Operations Manager and have recently configured alerts for "Inodes almost Full". I would like to set custom thresholds which I was able to do with "Volume Almost Full" & "Volume Full" notifications but it seems I am unable to set custom thresholds for this new inode alert. I checked under "Setup" --> "Options" --> "Default Thresholds" but again there are no setting relateds to this alert. In fact it doesn't even clearly state what the default threshold for this alert would be although I'm assuming it would be something like 80% for "Inodes Almost Full" and 90% for "Inodes Full". If anyone is aware of a way to set custom thresholds for these alerts or even provide the actual defaults it would be greatly appreciated.

How to mount NFS on XP??

community@netapp.com — Mon, 30 Mar 2009 09:26:46 GMT

Hi,

I am trying to mount a NFS share from our FAS3040 onto a windows XP box. I have installed Windows services for unix, and given the IP rw and root permisisons on the nfs export.

The problem I have is with user mapping. Do I set SFU to use password and group files? If so, how do I copy etc/passwd and the group file from the filer? Do I need to make one myself? Really struggling here to get this working, any help appreciated

Exchange 2003 volumes with SnapManager setup?

community@netapp.com — Wed, 04 Mar 2009 16:44:04 GMT

Hi,

I've read the SnapManager for Exchange Best Practices Guide (tr-3326.pdf) but I'd like some advice on my understanding of it before I go ahead with my Exchange/NetApp migration.

Our current Exchange2K3 environment is running on dedicated physical server, although we have just installed a new Exchange2K3 server on our VMware cluster which runs off a NFS volume on our NetApp. I now want to correctly configure our new Exchange server with SnapManager & move the databases to the NetApp before I start migrating our mailboxes to it from the old server (I figure it's easier & faster to do this with empy storage groups).

Our site currently contains around 150 users, and the total Storage Group size of all mailboxes is about 400Gb - so we're not talking 1000s of users and clustered Exchange - it's a relatively simple setup.

Now my problem: I want a simple, easy to manage volume setup that will alllow me to easily SnapMirror our Exchange data to our DR site (we already plan to SnapMirror our key VMs to our DR site which will include our new Exchange server).

We previously set this up in another site by creating a seperate volume for every Mailbox Store that we had, + 1 for all storage group log files, + 1 for our public folder store (this gave us 8-9 volumes to manage in total).

Is this overkill and can I/should I simply place all mailbox stores on the same volume? i.e.

- 1 volume for mailbox stores.

- 1 volume for logs.

- 1 volume for public folder store.

If anyone has any experience of deploying Exchange and SnapManager in a similarly small environment I'd really appreciate your views on this!

Regards,

Marc

Which fiber switch to buy?

community@netapp.com — Wed, 24 Jun 2009 16:05:27 GMT

We currently have two windows hosts using QLogic QLE2460's directly plugged into our NetApp filers. Each host has an active/passive connection to the alternate filer. We are now in the position of adding our 3rd fiber connected host and need to move to a fabric environment. I am looking for advice from users for brand and models of switch to purchase. I think we will perhaps have at most 4 fiber connect hosts. I was hoping to increase the bandwidth from host to filer buy making both FC cards active/multipath and of course increasing the number of connections from switch to filer as well. So from the get go, we would have 3 hosts x two 4gbit each, and 2 filers with two x 4gbit each, thus a total of 10 ports. Any advice appreciated...

New FAS3100 midrange platform

community@netapp.com — Wed, 30 Jul 2008 05:13:32 GMT

You've probably seen the press release or read about the new additions to NetApp's midrange family, the FAS3140 and FAS3170. As you would expect, these platforms feature innovations such as a HA configuration in a single 6u chassis and embedded NVRAM on the motherboard to add a slot for more scalability options. Not surprisingly, there are significant performance improvements as well.

A recent Tech OnTap article (How the FAS3100 Nailed the Price/Performance Sweet Spot) features two FAS3100 engineers discussing the new platform plus the results of three performance benchmarks.

The team would love to hear from you and get your feedback about whether this new platform helps address your storage requirements?

Snapdrive 6.1 - Vmware ESX 3.5 - slow startup

community@netapp.com — Thu, 13 Aug 2009 14:15:24 GMT

Hi,

I've the following issue:

When I upgrade snapdrive 6.0.2 to snapdrive 6.1 in a vmware guest os (windows 2003), the vmware guest will boot very slow.

As I suspected snapdrive, I can see that it takes a lot of time to start the snapdrive service by restarting the snapdrive and looking in the event viewer.

When I did a deeper inspection, I may conclude that snapdrive wants to talk to our virtual center and that's where it goes wrong. This will take about 5 minutes or longer. (I saw this when I did a repair of snapdrive 6.1 software and at the part where the setup connects to vmware, the timeout was seen)

Is there a way to debug this and see what's going wrong ?

Greetings,

Boeckx Kris

Can't upload .jpg for Edit Profile "Your Image", same file works fine as Avatar though

Looks like a minor bug in the Edit Profile screen where there is a section for uploading "Your Image" - I have tried various known good .jpg files without success. However I have uploaded one of the same files successfully as an Avatar (see attached sa.jpg). Is this a bug, is "Your Image" superfluous due to Avatar and thus should be removed, or ???

LDAP usermap or ObjectGUID for CIFS/NFS access.

community@netapp.com — Mon, 27 Jul 2009 21:40:30 GMT

Hi I am not sure if this is the right forum, but if anyone has experience w/LDAP and multiprotocol access, please email me. IHAC who would like to use LDAP instead of /etc/passwd & usermap for UNIX authentication and mapping.

I have two questions for now:

1. Not all UNIX usernames are identical to Windows unames. In this event, can NTAP still use LDAP for UNIX authentication and continue to use NTAP’s usermap for UID/GID to SID transfer? Or do I have to use a usermap file that exists on the ldap server? Can I use both?

2. They are using a “non-standard POISX attribute” and basically have 2 GIDs per username. One for production and one for non-production. Is this supported?

Also customer thinks that instead of binding to username, he can bind to ObjectGUID in AD instead of username, since the value is unique for each user. This looks to be a supported per MS: http://msdn.microsoft.com/en-us/library/ms677985(VS.85).aspx...

However, the article states the following:

The following IADsContainer methods are not supported by objects obtained by binding using the object GUID:

• GetObject

• Create

• Delete

• CopyHere

• MoveHere

How relevant are these containers for file access between UNIX/CIFS? In my scenario, files are created in CIFS and accessed as read-only in UNIX.

Replacing a defective disk Hitachi 144GB with a Seagate 144GB in a FAS270 Filer

community@netapp.com — Tue, 13 May 2008 06:15:44 GMT

I had a disk mark as broken in a FAS270 Filer. The OS is Data ONTAP 7.0.4

The disk model is: HUS103014FLF210 (Hitachi 147GB 10000 RPM, sysconfig -v = x274_hpyta146f10, firmware NA03).

The existent spare disk was used automatically to replace the broken disk.

I tried to replace the broken disk with the following disk:

Seagate 147GB 10000RPM,sysconfig -v=x274_10k7146f10, fimware NA01, disk model:ST3146707FC

After the replacement the disk not appeare as a spare disk as is normal.

In aggr status -r I have no spare and the the bay were the broken disk was before is not listed in sysconfig -r command.

At FC adapter level I can see the new introduced disk , its model, firmware etc (sysconfig -a command)

I don't know why the disk wasn't automatically recognize as a spare disk. The new disk has the same capacity and RPM like the old one.

I have in syslog the following messages:

Unable to build FCAl map... resseting device

Unable to communicate with device shelf, disk

In the disk matrix I saw that the actual firmware is N07 for the Seagate disk. Maybe is a a compatibility problem because my disk has only the NA01 firmware,

Can anyone help me to fix this problem?

Thanks

General Best Practice

community@netapp.com — Fri, 06 Feb 2009 02:35:09 GMT

Kind of new to all of this, but I am looking for general guidelines and any gotchas that may come with initial sizing of aggregates and raid groups.

I realize every situation is different, and that *true* best practice is to do an in-depth analysis of your applications, define the necessary IO required and build your SAN out that way. All well and good. That said -- is it typically better to have really large aggregates, or smaller ones, around 28 disks? One of our partners says that 28 disk aggregates is best practice, where other SEs say that it is best to have as large of an aggregate as possible.

Say we are getting 3 new disk shelves for an active/active 3040 cluster. Would it be best to use all 3 shelves in 1 aggregate? Have 2 aggrs, one that is 2 shelves and 1 that is 1 shelf?

What is best practice for raid group sizes?

Obviously we would be looking for the best way to carve this up with regard to performance, space-efficiency, fault-tolerance etc.

Any thoughts or real world configs would be much appreciated

Why should we disable dedupe when using Protection Manager?

community@netapp.com — Thu, 02 Jul 2009 14:47:27 GMT

Hi,

I have a question regarding the documents on NOW:

Backup und Debup

http://now.netapp.com/NOW/knowledge/docs/ontap/rel7311/html/ontap/rnote/rel_notes/concept/c_oc_rn_lim-dp-sv-protmgr-dedupe.html

Do not use Protection Manager 3.7 on volumes that have deduplication enabled.

Okay, I know OM 3.7 is not aware of Dedupe. But it is still possible to do backups with dedupe enabled on the primary side.

My Customer found this and is asking if this also applies for the PM in 3.8 Version.

Additional question is...

Do we need Provisioning Manager license for future Protection Manager installs, if we want to use dedupe on primary and secondary snapvault relationship? (got something in my mind from talking with PMs)

OSSV dataset resource restore failing with "The reason is Parsing error in results: Input is not proper UTF-8, indicate encoding"

community@netapp.com — Fri, 13 Nov 2009 18:31:41 GMT

Getting this error when trying to do a restore from Netapp Management Console on a resource with a dataset. It only gives this error on 2 specific resources under this dataset. The rest of the resources work fine and I can restore them without issue. I thoought maybe that the resouces were out of sync so I tried a resync but it made no difference. When looking at the host for these resources I can explore through the direcorty structure without issue so it seems to be able to see it from that point.

Has any one seen this issue previously and are there any recommendation on how to resolve it?

Any help that can be provided is greatly appreciated.

Simulator 7.3.1 hangs on first run

community@netapp.com — Fri, 08 May 2009 11:57:39 GMT

Hello!

I'm trying to run 2 simulators on a virtual Ubuntu 8.04 platform. The first simulator is 7.2.6.1 and it worked straight away, no problems. Subsequently, I tried to install the 7.3.1 simulator on the same platform, by changing the install directory to /sim7.3.1 (as suggested by simulator installation guide), and it went off without any problems.

However, after installation, I started the first simulator but after I try to launch the 7.3.1 simulator - this is what I get:

root@linux-desktop:~# sudo /sim7.3.1/runsim.sh

And that's where it hangs. I've tried other installation parameters but it's still the same.

Some info: I've allocated 512 MB of RAM to this virtual machine, and the simulator installation guide says it should be able to support at least 2 simlators if they're granted 128 MB each on installation.

This is supposed to be pretty simple to use. What am I missing?

Thanx in advance,

New website!

community@netapp.com — Wed, 19 Mar 2008 17:56:01 GMT

All,

I have just completed posting our new draft look of the ATL NUG website. Please review and give input. I am looking for takers to absorb the webmaster duties of course all free of charge! Let me know if you are interested in this. There are several items left to complete to bring it to 100%. But it is a good start.

The site was made from scratch in Adobe Phototshop CS3, Adobe Dreamweaver and GoLive CS3. If you know how to use these products and you are still interested in maintaining the ATLNUG site please let me know ASAP!

Here it is: http://www.atlnug.org/ we have also purchased .com.net as well. They all point to .org. The all the original domain names purchased are now turned off and will expire, all in accordance to the NetApp legal letter on name use.

Thanks,

NetApp NFS with VMWare

community@netapp.com — Sun, 04 Jan 2009 13:27:43 GMT

I am currently designing a virtualized infrastructure for business critical applications. In researching storage systems I found many people recommending NetApp filers and NFS.

I have looked at product information on netapp.com, read the VMWare & NetApp best practices guide and browsed NOW. However there seems to be a bit of a gap in information between the very high level overview of the netapp.com products pages and the technical details of NOW. I am meeting with NetApp in the next week, but was hoping to clarify a few questions and get some experience from NetApp + VMWare users.

Current storage requirement is only about 2.5TB and I understand de-duplication would likely save me some space. Given the data growth rates of my applications it's very unlikely I will need more than 10TB in the next five years. Looking at the range of NetApp filers it seems something like a 2050 would easily do the job capacity wise. Does a 3100 series filer offer any more functionality other than greater performance and expansion capability?

I envisage having a two controller filer in our local data centre and another filer at our DR site. What should I use to synchronise the local and DR site?

What level of integration is there between VMWare Infrastructure and NetApp filers? I have seen a NetApp blog post about VMWare tools.

Is an NFS licence included with the purchase of current NetApp filers? The technical specification on the 2050s and 3140s I've looked at mention support for NFS, making it sound like it's included, but I have seen several posts on the Net saying you need to pay $13,000 per filer for the NFS licence.

Finally I'd like to suggest that NetApp add more technical information to netapp.com. The product pages don't really explain what the different software does in any detail nor make comparisons between filer models easy. Reading the page on virtualization gives you very little idea of what NetApp & VMWare can do. While NOW appears to be an excellent resource, NetApp could really do with exposing more technical information on its public-facing web site to help newcomers.

Thanks,

Will

Simulator upgrade from 7.3 to 7.3.1

community@netapp.com — Sat, 21 Feb 2009 20:28:33 GMT

More of an FYI rather than a question....

I tried to upgrade my 3 simulators from 7.3 to 7.3.1 (running under CentOS 5.2 x86-64 VMware Guests using VMware server on CentOS 5.2 VMware host) After restarting the simulators (post 7.3.1 upgrade), they all had console errors relating to Java. The end result is that Filerview was not functional.

Original errors on the consoles or in .bglog after the upgrade follow.....

java.lang.NoSuchMethodError: invoke_v6

Fri Feb 13 14:19:05 EST [httpd.servlet.cantFindMethod:warning]: Could not find Java Servlet Method; there is a problem with Java Virtual Machine. FilerView(R) will not work correctly until you resolve this problem.

If you try to access the simulator via a web browser you get...

Error 500

Servlets not enabled

A temporary workaround for this issue:

1) Fresh install into an alternate directory on Linux host (ie - /simnew)

2) Bring both simulators up simultaneously

3) Mount the /etc NFS export from both simulators and copy all the files from /etc/java from the fresh install into the /etc/java on the upgraded install

4) Reboot the upgraded simulator (everything comes up clean and filerview is functional)

Note - It appears the simulator upgrade process fails to update one of the java files in /etc/java. I copied the entire /etc/java directory but the one file that seems to be the culprit (based on filesize) is "netapp.zip".

I thought this may be of use if someone else encounters the same issue. As mentioned, this occurred on all of my simulators when upgrading them from 7.3 to 7.3.1.

Jeff

FAS to V-Series Conversion

FPolicy FP_ScreenRequest2 problem

community@netapp.com — Mon, 29 Jun 2009 14:39:46 GMT

Hi, Guys

Now If I pass no additional parameters to FP_Registration, just "\\computer\domain", I receive notification through FP_ScreenRequest and displaypath is valid file access path. But if I pass some additional parameters to FP_Registration, like "\\computer\domain\size_and_owner=true", I will receive all notifications through FP_ScreenRequest2, where request->sr_displaypath would contain the data which was in accesspath (with FP_ScreenRequest notification) and request->sr_accespath is NULL. So with FP_ScreenRequest2 (which I really need to get notified about reads and writes) I did not get displaypath.

The question is: is it some kind of bag or misconfiguration of my environment? is there some way to garantly convert accesspath to displaypath?

NetApp System Manager - beta feedback

community@netapp.com — Mon, 23 Mar 2009 15:17:39 GMT

Hi Guys,

I just got hold of NSM and it looks really pretty, so much better than the web interface. I wonder if you still accept feature requests for the product.

I'd love to get a centralized view of my aggregates/volumes/luns/init groups. It's a bit tiresome to switch views every time I need to check something out. I'm thinking of a folder tree-like view of every element of the device.

The current LUN view has a major downside: I cannot immediatly see which lun is assigned to which initiator. The web interface had this info on one page, now I have to click thru all LUNS to get this info, which is kinda painful .

The LUN level snapshot management is a bit misleading... it shows the volume snapshots and not the LUN snaps. Whereas the LUN level snapshot functionality is not even wired into the interface (I wonder if this this is intentional?)

renaming an initiator group gave me an error stating that this operation has to be done with the -f switch. Yet, the rename was successful.

Regards,

Bali

SnapMirror Consistency Group

community@netapp.com — Mon, 14 Sep 2009 06:28:21 GMT

Hi Team,

Hi Team, Is there Any way to define Consistency Groups with SnapMirror ? My customer spared his data across few volumes he wants that all volume will be synchronize on the same time on the Destination. In case of Network failure, if the updated Data didn’t SnapMirror’d to destination completely ,the Data is not Valid on the destination. The Data is Flat Files with CIFS protocol. Any recommendations ? Thx --Yossi

Both system name and serial number comes as same from the simulator. But in real time , I think system id will be different for the main filer and v-filer. Can you please confirm.

Performance Issue with NetappFAS2020 (1Head) and ESX 3.5 (on HP DL380G5)

community@netapp.com — Tue, 30 Sep 2008 16:50:41 GMT

Hi,

we've got an big performance issue in our SAN config: Perhaps someone can help me??

System config: Hardware: 2x HP380G5 DualCore, Emulux HBA, FC, 2x FAS2020 incl. 12 HDD SATA

Software: ESX 3.5 Enterprise (HA, DRS, Vmotion), Data Ontap 7.2.4L1

The storage performance on the FAS2020 in indiscussiable. Best i can see this when i start an esxtop from one of the esx-servers: (JPeG1). Pleas take a look at DAVG/wr and GAVG/wr. And look: There are only some i/o (CMDS/s). I've take this snapshot in the evening. Sometimes in buisniss time the values of DAVG and GAVG goes over 300 and more!!!

Can someone help me? Thanks for all kind of help!!

Sorry for my bad english

'Single Image' Clusters with same PWWN's?

community@netapp.com — Fri, 24 Apr 2009 17:39:36 GMT

Gurus,

We have our client running a bunch of NetApps FAS3070 in single image mode (as clustered pairs).

But in one of the pairs, we noticed that they have adapters which share the same Node WWN (which is expected), but I also see that the port WWN's are the **same** for both the Filers. How could this be? I saw a simillar complaint by another person on a VMWare forum. By having same Port WWN's for the both the filersin a cluster, wont it cause confusion at the OS level (OS Handles that is), as to where the disks really are?

Also note that both filers have all ports as local, with parner-adapter 'none'. Is this setup even valid?

Please explain?

Thanks

Is deduplication safe for my data?

community@netapp.com — Tue, 01 Jul 2008 16:09:34 GMT

Deduplication eliminates redundant files stored on disk. Since you are only storing a single copy of the data, this raises the issue of the reliabilty of storage systems that offer dedupication. Here is an article that digs deeper into the subject: http://www.netapp.com/us/communities/tech-ontap/dedupe-0608.html

Anyone care to comment on steps they take to protect their deduplicated data?

Moving volume to another aggregate

community@netapp.com — Mon, 18 May 2009 08:24:36 GMT

Hi All,

Is it possible to move a volume to another aggregate on the same shelf?

If so, could someone point me to a procedure on how to do this?

How can I set acces rights to a share ?

community@netapp.com — Wed, 25 Mar 2009 10:39:45 GMT

Hello everyone.

I'm trying to create a script using perl api which create a qtree and the share related to.

Both works fine, but I need now to restrict access to filesystem and shares (ntfs security), using APIs if possible.

Is there anywhere in APIs something like the "cifs access" command ?

for the filesystem security, my only solution is creating a file that I will apply with the "fsecurity" command. Can I do the same with APIs

Snap Restore problem

community@netapp.com — Tue, 04 Aug 2009 10:51:20 GMT

Hi all

I am trying to run a single file "Snap Restore -t file" command on my NetApp Filer from a command-line inside the filer.

I have both a CIFS volume and a NFS volume.

Snap Restore works fine when I run the commands inside my CIFS volume.

But when I use the Snap Restore command inside my NFS volume, I get the messsage "File does not exist in snapshot."

But if I browse my Filer (using WinSCP) I can see the file, I am trying to restore, inside the ~snapshot folder?

The NFS volume is used for my VMware server files.

These are the details:

NFS volume name is: tknfsdata_01

The path to the file I am trying to restore is: /vol/tknfsdata_01/vmfs/volumes/Datastore1/tkweb/tkweb.vmx

(This path has been copied from the WinSCP browser window)

My command:

TKNAS1> snap restore -t file -s nightly.0 /vol/tknfsdata_01/vmfs/volumes/Datastore1/tkweb/tkweb.vmx

WARNING! This will restore a file from a snapshot into the active
filesystem. If the file already exists in the active filesystem,
it will be overwritten with the contents from the snapshot.

Are you sure you want to do this? y

You have selected file /vol/tknfsdata_01/vmfs/volumes/Datastore1/tkweb/tkweb.vmx, snapshot nightly.0

Proceed with restore? y

snap restore: File does not exist in snapshot.

I suspect that my path is wrong, but I can´t see where??

Are there any commands in ONTAP 7.3.1 that can be used to browse the filer, like "cd" or "ls -l"???

Best regards

Jens Nielsen

Decru Software Decryption and port consolidation/performance

community@netapp.com — Tue, 05 May 2009 19:47:42 GMT

IHAPC with the following issues / questions regarding tape encryption:

1) He has 6 tape drives and wants to buy the 10-port F-Series, which means he'll need to "consolidate" 2 tapes to run over 1 of the port-pairs (in-out).

He has no issues around security with this coniguration but wanted to know if there are any best practices / guidelines to preserve maximal performance (I've checked and both tapes have a smaller throughput than a port-pair can support.

2) If they do encrypt on the main site and use LKM to backup the keys - will there be a way to access the backups on a remote site (which holds the tapes) using any sort of software ? they are afraid of being locked down to the technology due to long retention times,and wanted to know if they'll always need the box to access the data (performance is not an issue when accessing the data in the remote site).

Appreciate the input!!

Hopefully someone can help.

I need to integrate a Filer with an OpenLDAP database to provide authentication and authorisation for NFS exports.

I have downloaded and followed the instructions in TR-3464 "Integration of a NetApp Storage System with a UNIX based LDAP server" to no avail.

I can connect to my OpenLDAP server with an LDAP browser with no problems, but no matter what, my Filer still seems to be pointing at its local files for authentication.

I HAVE made the changes to nsswitch.conf to put LDAP first. I have also rebooted the filer just in case.

I am problably just missing one important step, but what it is I do not know.

Any help would be appreciated.

Many Regards

OnTap FPolicy FS_OP_DELETE Problem

community@netapp.com — Tue, 20 May 2008 14:25:34 GMT

I am using the latest Manage OnTap SDK 3.0 and filer fas250 with 7.3. Here is my filer sysconfig:

When I am trying to delete the file from the filer, the FP_ScreenRequest2() and FP_ScreenRequest() will only respond with FS_OP_OPEN, not FS_OP_DELETE.

Why the FS_OP_DELETE operation is not sent? I need the FS_OP_DELETE to monitor if the file is deleted. Has anybody seen the similar problem?

Thanks.

Deciphering the switch config - How to configure single, multi and LACP vifs

community@netapp.com — Thu, 31 Jul 2008 08:02:52 GMT

This has always been a particularly challenging debate for a number of people.

As businesses grow, there is often separation of Storage, from Networking, from Operations, from systems.

End result is a lot of cooks in the kitchen, but no one true recipe to reference that everyone can agree upon.

I'm looking to put an end to that debate, atleast in the pockets which will support it.

So, the question I raise out to you folks - Interested in seeing a solid, best practice, confirmed and validated "Switch Configuration" tutorial for VIFS?

I will not guarantee every configuration the world may offer, but some definite guidance, best practices, and "working configs" of the world - Starting with Cisco.

While not every switch is created equal (IOS vs CATOS, etc) there are some things we can all agree on - That every configuration should meet a baseline.

If the interest is there, I'll build out my lab, test, validate and open the 'suggested' config to the masses for your thoughts on the matter.

So, the ball is in your court - Interested in not having to re-invent the wheel when it comes to get a networking config validated?

Take care,

christopher

How to seed first SnapMirror w/o using network?

community@netapp.com — Fri, 20 Feb 2009 21:50:40 GMT

I will be deploying a FAS2020 at a remote site that has 2-TB of data. I plan to setup and migrate from direct-attach in a Windows environment. After the migration, I'd like to use SnapMirror to mirror my data back to central site on a FAS3140A. The problem is bandwidth for initial sync. The 2-TB will take about 90-days to move across a 3-mbit connection. We're okay with the write updates, as these are only about 1-GB per day. Any ideas on how to get the initial data over to the central site without physically moving the FAS2020? Can we backup to a tape via NDMP and load the tape at the central site?

Simulator network issues under W2K8 R2 Hyper-V

community@netapp.com — Tue, 30 Jun 2009 10:02:56 GMT

Hi,

I'm having network troubles in my 7.3.1 Simulator running in a Ubuntu Server 9.04 (x86) VM on a W2K8 R2 Hyper-V Host.

The issue is that I am unable to access the simulator via IP, nor can I ping anything from inside the simulator. I know that the networking to the Ubuntu VM is working because I can ping and access it's IP from hosts outside the environment, and from inside the Ubuntu VM I can ping to hosts outside the environment. But when I start the Simulator the networking just doesn't seem to be able to get out onto the real network.

The setup is as follows:

Hyper-V Host with 2 x physical NICs
- NIC1 connected to the physical switch and configured with IP Address for managing the Hyper-V host
- NIC2 connected to the physical switch and configured in Hyper-V as the physical interface to use for a Virtual Network called "External"
Ubuntu VM configured with 1 x Virtual NIC which is connected to the "External" Virtual Network
- NIC comes up in Ubuntu as "eth0" and is configured with an IP Address appropriate for the "External" network and is able to ping to hosts outside the environment (ie: the networking works)
Simulator configured with one standard settings, no VIFs
- NIC "ns0" configured with IP Address in the same subnet as the Ubuntu VM
- Media state for the NIC in the Simulator shows as "auto-100tx-fd-up"
- Unfortunately I am unable to ping any external host from inside the Simulator, and likewise I am unable to get to the IP of the Simulator from outside of the environment

I have attached a JPG of the networking as seen from Hyper-V.

Does anyone have any suggestions for what I should try?

Thanks,
Corey.

Can we add new disk pool in the simulator [ I am not able to create aggr]

community@netapp.com — Mon, 28 Sep 2009 05:27:51 GMT

Hello all,

Can we add a new disk pool in the simulator [ I am not able to create the aggregate with syncmirror options ]

root@redhatas4 ~]# sim aggr create aggr2 -m 6

aggr create: Couldn't create aggregate: 3 disks needed from each pool, but no disks are available in Pool1.
You may force create by using options -f and -d to specify disks
from both spare pools. This is not recommended, because having all the
disks in a plex originate from a single pool maximizes reliability with
synchronous mirroring.

[root@redhatas4 ~]# sim aggr status -s

configuring ndmp.enable option using the sdk failed.

community@netapp.com — Sun, 28 Dec 2008 16:54:28 GMT

Hi ,

i'm trying to use the SDK to change OnTap options via the perl API.

most of the options are working great but two of them seems to have problems :

1) timed.proto - even tough the man pages say that sntp is supported and i can run it using the cli

it won't work on the sdk (workaround i found is to use ntp instead)

2) trying to set the option ndmpd.enable result in "No such option: ndmpd.enable, again

setting it from the cli work's fine.

i'm working with OnTap 7.2.4 on FAS270 and using sdk-3.0R1 with perl.

Thanks in advance for any reply

Newbie: Getting a NetAppFAS980 to boot

community@netapp.com — Wed, 30 Sep 2009 19:27:14 GMT

Howdy,

My name is Ross and I am a graduate student worker at Texas A&M for the CS group here. We recently received a big donation of 4-5 racks of NetApp FAS900 series controllers and drive bays/drives. Right now I am simply trying to get the first rack (A FAS980 with 12 drive bay racks) to boot to a working prompt so I can further investigate what needs to be done. The approach so far is incremental... I have the main device (FAS980) and one drive controller plugged into the main device via fiber. We have a monitor/keyboard/modem device which is new to me but I think everything is set up that needs to be. Correct me if I am wrong, but the OS sits on the CF cards that are inserted into the main device. We have an OS loaded on there and are trying to get it to boot, but when it has the following sequence leading to an apparent crash with no prompt ever appearing.

Disk label processing fail

Error dumping core

Halting

Is there a guide somewhere on how to get started with the FAS980 system? Any help pointing me in the right direction would be great. I know the general forum etiquette about searching for solutions and believe me I have tried... Seems netapp has their documents locked down pretty good.

Thanks,

Ross

unable to create snapsots on a volume

community@netapp.com — Sun, 11 Oct 2009 04:06:47 GMT

Hello folks,

I establish a snapmirror relation ship between a source volume of size 3.0TB to destination volume 3.5TB.

when I initialize the snapmirror process it says snapmirror aborted.

Then i started creating snapshot manually but it says no free disk space on source volume I already started increasing the size of the source volume but still it tell's me no free disknspace.

please solve my issue as i have 3 lun's are carved on source volume and it is in production.

Performance Advisor - Volume Latency View

community@netapp.com — Wed, 17 Jun 2009 14:59:51 GMT

In PA - Volume Latency View, two questions:

1) Why does NFS Latency by Optype contain different data than Overall Latency by Optype? The volume only contains data accessed through NFS. The latency in milliseconds is off by at least factor of 10.

2). In the NFS Latency by Optype view what is the difference between nfs_latency and the other counters? I'm aware of the differences between read/write/other. Is nfs_latency meant to be a sum of those three? If so, it's off by almost a factor of 100 (sometimes almost an order of magnitude).

thanks,

sean.

Whether to split CIFS volume into multiple volumes of like-data for de-dupe purposes?

community@netapp.com — Sat, 31 Oct 2009 10:08:40 GMT

Hi,

I have a 600GB volume that conatins all CIFS data for an environment including home directories, roaming profiles, TS profiles and general business data. I'm planning to move all this data to an ASIS-enabled volume, but I am unsure whether there would be any benefit from a de-duplication point of view in splitting the volume into multiple (i.e. one for home directories, one for profiles, one for business data).

From my understanding, there is no need to do this (surely the data would de-duplicate just as well whichever volume it is in?), but a colleague has recommended that I do.

There are obviously other considerations such as snapshot frequency, future snapmirror options, flexclones etc ... but from a de-dupe point of view, is there any benfit to splitting the like-data into separate volumes?

Any suggestions welcome!

Snapmirror between FAS3020 and FAS270

community@netapp.com — Mon, 30 Mar 2009 16:00:01 GMT

Is there a problem when mirroring between a FAS3020 and FAS270?

I have some data in test on a FAS3020 and trying to mirror to FAS270 also in test but for some reason the mirror will not initialize. I have tried mirroring from FAS270 to 3020 and all OK.

Seems strange, all configure files look ok, OnTap is the same version, snapmirror.access is correct, well as far as i can see.

The message from the FAS270 (destination) is as follows:

"Transfer aborted: update from source not possible; snapmirror may be misconfigured, the source volume may be busy or unavailable."

Message from FAS3020 (Source)

"snapmirror: Access Denied from if = virtual_live, src ip = 10.10.x.y, dst ip = 10.10.x.y. Check options snapmirror.access."

Please help!!!!

What's the impact of enabling Flexshare?

community@netapp.com — Mon, 11 May 2009 14:32:06 GMT

I have a 3070 (7.3.1P2D11) that runs pretty hard (systat -x shows pretty constant low 50s) and I'd like to enable Flexshare but I am concerned about the overhead. Basically I have a low utilization volume that absolutely has to go to the front of the queue and it's sharing spindles with our test data warehouse. Normally things are fine but occasionally we'll do some massive data loads that push an extra 3-4k IOPS on that controller.

Think it's safe to enable? Can I just shut it off with no repercussions if it does seem to cause an issue?

Adding disks to a filer

community@netapp.com — Mon, 15 Sep 2008 23:21:35 GMT

Hello all,

While setting up the simulator, It asks for the number of disks to be added to the filer.

Maximum disks it could able add is 28 .

My question is the number 28 restricted to only simulator or for a production filer as well.

In other way how many maximum disks we can add to a filer.

Various questions around SM-MOSS

community@netapp.com — Fri, 12 Jun 2009 15:12:24 GMT

Hi all, My customer has some questions regarding SM-MOSS 2.0.1

Agent Monitor: Which account is required Local System ou SRV_SMMOSS ? Which right for this account ?
Device Manager: If we add a Physical Device, do we duplicate the backup ? What is the expected behavior ?
Account Manager: Do we need to define a service account ?
Backup BuilderWe plan to create 2 Backup Plans:- one for the entire farm ( once a day)- the other one for the Content DBs ( every 3 hours) What’s our best practice ? What’s the recommended verification strategy ? Some items like WSS_Help_Search, SharedServices1_Search_DB are not selectable, is it normal ?
Restore Controller: When we select “All Plans” , the timeline browser don’t present all the available Time Points. Do you already seen this behavior ?
Does it exist some case where the GUID of the site is modified after a restoration? In others words, do we need to resync the ContentDB after a restoration ?
When I make a backup with SM-MOSS, the status of the farm backup is “completed” but into the log I see this message concerning the snapshot taken for the lun storing the Index “Error: Unable to create a Snapshot copy. Please check the application event log for more details.
Do we recommend to take manual snapshot for some LUNs like lun storing the Media Data ?

Thanks for your help. Regards,

SnapManager for SQL over FCP in VMWare ESX Restore Question

community@netapp.com — Wed, 22 Apr 2009 14:48:05 GMT

We currently are using SnapManager for SQL, snapmirroring the data to another data center, and we currently have a script setup to automate the restore process. The machine is a Windows Guest running on ESX 3.5 over FCP RDM luns. Currently we are using the sdcli disk connect command to attach these LUNS to are DR system when we want to mount the databases, but this process is very slow in ESX with FCP luns as it has to rescan the HBA each time it attaches a drive to the VM.

Initially we left the drives connected to the VM, but did not assign drive letters in Windows. The annoyance we ran into in that scenario was after we detached the databases and removed the drive letters from the system we would sometimes see Delayed Write Fail messages. We built pauses into the script to wait after detaching the databases, but it seemed like we always ran into that problem. Does anyone have any recomendations in this regard? What are other users doing? Is it best to just disconnect and reconnect the drives each time, or should I just build in longer pauses to try and avoid the delayed write fail messages?

Thanks,

Hi ,

I have an issue.

When i run the "Storage show " command, it gives 'SANOWN not enabled' at the end. I have connected this filer to a SAN switch. Also when i run 'fcp show adapter', it gives an error

"fcp: No FCP Target Adapters are present in this system."

Can someone please tell me how can i enable the SANOWN . Also how can i get the fcp adapter list and its properties.

FYI, the fcp target is licensed on this filer .

volume-rename and luns

community@netapp.com — Mon, 10 Mar 2008 05:46:56 GMT

hmmcintosh

on 9/2/07

Asked

When I call volume-rename, and then call lun-list-info, I get paths that use the OLD name for the volume. This seems to continue for a varying amount of time (minutes, not just seconds) after the volume-rename, and then lun-list-info starts returning paths with the NEW name for the volume.

(One thing that seems to force lun-list-info to start using the new volume name is using the "refresh" button in FilerView when looking at the "LUNs | Manage" window.)

Is there anything I can do to cause lun-list-info to start returning paths with the new volume name?

SnapRestore in SAN environment --- Not work

ngoctuan.do@orange-ftgroup.com — Fri, 19 Sep 2008 14:08:42 GMT

Hello,

I see in the book : "Data ONTAP^TM 6.4.2 System Administration Block Access Management Guide" the way to use SnapRestore to restore of a LUN

Restoring a snapshot of a LUN

To use SnapRestore to restore a snapshot of a LUN, complete the following steps.
Step    Action
1          From the host, stop all host access to the LUN.

2          From the host, if the LUN contains a host file system mounted on a
            host, unmount the LUN on that host.

3          From the filer, unmap the LUN by entering the following command:
            lun unmap lun-path initiator-group

4          Enter the following command:
            snap restore [-f] [-t vol] volume_name [-s snapshot_name]

Step 1, 2 and 3 is OK but in step 4 i have the error

> snap restore -t vol /vol/vol3 -s mysnap1
snap restore: Has extra arguments.
> snap restore -t vol vol3 -s mysnap1
snap restore: Has extra arguments.
>

first , how can i solve the issue ???

second; i think the steps above : "it is a reverting a Volume from Snapshot", What is your ideal ?

Configuration Management - Gap Analysis

community@netapp.com — Sat, 15 Mar 2008 02:28:00 GMT

I thought I'd share a couple of Configuration Management experiences with you...

Last month I went into a customers account to perform a live demo/evaluation of Operations Manager in their environment, one of my preferred ways to demonstrate it's functionality (see demo post - http://communities.netapp.com/post!input.jspa?communityID=2026); During this time I was attempting to show the prospect the use of run cmd option (which runs an Ontap command on a controller or group of controllers); Although we couldn't run it as we'd not setup ssh and rsh was disabled on all controllers as standard;

Immedietley I thought "hmmmm rsh disabled as standard" sounds like a job for configuration management - so we created a quick configuration (pulled from an existing controller) checked the rsh option (value to disable) and then the Compare configurations across their entire estate (24 controllers); Guess what ? we found 8 controllers were rsh was in fact enabled - a great gap analysis!!; Better still we could then push the configuration out to go set these options (although their change management procedures and process stopped it us from deploying the change there and then)

Needless to say the prospect was impressed and is now a Operations Manager customer;

I also had a customer once tell me they had a performance problem with some NFS volumes on their controller - the administrator told me that the two controllers (whch formed a cluster) were configured identically and yet one exhibitied the poor performance were as the second was fine; Again I challenged this "they are configured the same" statement and created a configuration from the good controller and checked it against the bad controller; Immedieltely hightlighted was a misconfiguration in resolv.conf - once recitified the performance problem went away This was nice as many times people believe you need large complex environments to realise the benefit of OpsMgr

Any more configuration management stories or use cases ?

Question regarding fas270 and data ontap 7.2.2

Hello,

I'm trying to extend a VM data volume from 175GB to 220GB that has been mapped directly to a lun but I receive a file cannot be found error (25). After looking on the SAN side Under the Volumes -> Manage interface, the total volume size displays 220GB with 44GB available. Under Lun -> Manage, the lun size is 175GB. How can I change the lun size to be 220GB?

Thanks in advance for any help provided!

Thin Provisioned LUN not showing true space usage

community@netapp.com — Fri, 06 Nov 2009 21:32:01 GMT

Hi. I've implemented thin provisioing for a customer's VMWare VMFS datastore LUNS. Everything in the beginning was working as expected. The space that was actually being written to (i.e. add a 30GB VM to the datastore) was being reflected on the filer. I could see this through the following command:

aggr show_space -g

The allocated and used space would be identical - as expected. Now, let's say I created that thin provisioned LUN to be 350GB. ESX would think it's getting a 350GB LUN and my space used on the filer would state 0% used. It's only as I start adding VM's does this increase the %used space...fine.

Now, let's say I've added enough VM's that the entire 350GB is used up. When I run the aggr show_space command I see 350GB allocated, 350GB used - that's fine.

Now, I vmotion a bunch of VM's from that datastore to a different datastore, leaving 100GB of VM's on the original datastore. If I take a look at the ESX datastore I now see that out of the 350GB allocated, I have 100GB used and 250GB free - nice. BUT, when I take a look at the filer and run the aggr space_show -g, I still see 350GB allocated, 350GB used - even though from a VMFS perspective this is not the case.

I'm assuming this is the same issue that I've faced before with WAFL not knowing what's happening within VMFS when VMFS frees up space. WAFL doesn't own the VMFS so it can't reflect the changes that VMFS makes when it "deletes/moves" files.

The Space Reclaimer is a nice tool that is used within Snapdrive to reclaim blocks that have been "freed", essentially passing this information to WAFL so it knows how to update the space metrics. My question (and my client's question) is how do I reclaim that space on the filer AFTER the thin provisioinmed LUN has reached a certain size and then decreases - either because a VM was destroyed or a vmotion moved it to another datastore. It would be nice if there was some Space Reclaimer feature within ESX whereby I could either manually invoke or schedule it to run against a VMFS datastore.

I know that there is now the Virtual Storage Console - a vCenter snap-in. I wonder if space reclaimer could be added to that? Seems like the perfect place to put it.

Does anyone have any suggestions as to this dilema?

Thanks

Used Space Discrepancy in ONTAP

community@netapp.com — Tue, 07 Apr 2009 18:06:00 GMT

Hi,

I am having trouble viewing the amount of space used on each of my SnapShots. While this fucntion is working on all my other volumes one in particular has stopped showing the space usage and total in ONTAP. Does anyone have any ideas what may have caused this discrepancy? The reclaimable space does show space used and there are methods through putty to view this but I would like to see this in ONTAP.

Thanks,

Dave

ESH2 and ESH4 compatibility

community@netapp.com — Thu, 28 Aug 2008 20:59:24 GMT

Currently my site has a FAS 270c with a DS14mk2 (ESH2) diskshelf attached. Recently, my company purchased two additional DS14mk2 (ESH4) diskshelves. After assigning unique shelf ID's to the new shelves and properly connecting the systems, I receive a warning indicating a "disk shelf configuration error". In the Disk Management window, all my new disks in the new shelves have "?" in the Shelf and Bay columns.

The system still lets me add disks to my current volume. All normal functionality appears to be fine. The only indication of an error is the global "Disk Shelf Configuration Error" and the lines in my syslog that say ...

"Enclosure Services has detected an error in access to shelves or shelf configuration on 0b."

"Enclosure Services unavailable for one or more shelves on channel 0b."

Is this a known issue with attaching ESH4 disk shelves to an ESH2? Is there a firmware update or procedure to fix this?

Any and all advice is welcome!

Thanks

Looking for a comparative betwwen FAS6040, FAS3160 and FAS3170

community@netapp.com — Fri, 26 Jun 2009 12:55:19 GMT

Hi everybody

Not wanting to reinvent the wheel,

a customer here is asking for one comparative (not only in figures, I mean, not only in HW components memory-cache, FonrtEnd ports, Disks expansion, Slots expansion, and so on), but in any perfomance metrics that somebody has already measured: IOps, MBps, Exchange mailboxes, ...

I am searching for some numbers to differentiate one FAS6040(A) among FAS3160(A) and FAS3170(A) supposing all the cabins would have same number of disks drives in the trays backend

Spare disks

I would like to create the biggest volume (and LUN) possible, with:

- snapshots disabled (0% reservation set for snapshots, nosnap for the aggr0 and volumes) - already done,

- one spare disk (as shown above) - already done,

- vol0 size reduced to minimum (10GB) - already done.

- size guarantee enabled for the volume,

What is the biggest size i can get without issuing the guarantee=volume(disabled) problem?

Weird thing happened, i had a 5,7T volume (vol1) on it with guarantee enabled for the volume and LUN with the maximum size possible and after some time the guarantee switched to disabled. I've destroyed the LUN and vol1, and now i can create volume with a max size of 3,7T. I've found out that WAFL reserve is taking over about 2,4TB so this is probably the lost free space:

aggr show_space -h
Aggregate 'aggr0'

Total space WAFL reserve Snap reserve Usable space BSR NVLOG A-SIS
6827GB 682GB 0KB 6144GB 0KB 0KB

Space allocated to volumes in the aggregate

Volume Allocated Used Guarantee
vol0 12GB 649MB volume

Aggregate                       Allocated            Used           Avail
Total space                          12GB           649MB          3777GB
Snap reserve                          0KB             0KB             0KB
WAFL reserve                        682GB          2407GB             0KB

how can i recover (free) this space and use it in volume? What am i doing wrong?

Extra interfaces on the Simulator

community@netapp.com — Tue, 09 Dec 2008 16:31:28 GMT

I'm really happy using the Simulator. Unfortunatley I'm unable to get the simulator to raise multiple interfaces. It always offers NS0 connectivity which it maps to e0. I would like to have an e1 e2 e3 as well if possible

Why ?

I want to simulate some changes we intend to put in place for VMWare ESXi in our infrastructure and that involes some repositioning of connectivity

Anyone have an answer

Thanks in advance

snapdrive, windows 2008 X64, pass through authentication

community@netapp.com — Sat, 07 Mar 2009 21:22:42 GMT

I have a filer which is not part of a Active Directory domain. It's running 7.2.5.1. There is no CIFS license installed on the filer (and none forthcoming). Snapdrive 6.0.1 is installed on a Windows 2008X64 server. I'm attempting to configure pass-through authentication as described in the docs.

I've created a local snapdrive user and add it to the Windows local administrators group. I've created a local user on the filer called snapdrive and added it to the BUILTIN\Administrators group on the filer. The passwords I've created for the Windows snapdrive user is identical to the filer snapdrive user.

I've installed snapdrive as the local snapdrive user. Everything looks fine when I open up the Snapdrive MMC. When I attempt to create a disk via snapdrive I get the following error:

SnapDrive Error

Access is denied

I've configured pass through authentication successfully in the past on Windows 2000/2003. Not sure if this is a Windows 2008 problem. Firewall has been completely turned off the Windows server.

Any suggestions?

Available Space on volumes with snapshots

community@netapp.com — Tue, 02 Sep 2008 12:03:55 GMT

Hello,

I'm having a volume with 15% snapshotreserve set (but disabled). Now I want to create some Luns in that volume.

To do that, I compute the capacity of the Luns by dividing the available size - which I get by the parameter "size-available" of the OnTapi-command "volume-list-info" - with the no. of luns. When I then use "lun-create-by-size", I get an error, that the device is full. So how much space can I really use? And what is that space used for (on my simulator over 100MB in an 9GB volume)?

Correct Sizing of Datafort appliances

pspringfield@bellmicro.eu — Tue, 10 Nov 2009 17:09:25 GMT

Hi,

I'm trying to figure out how to create an accurate specification of Decru for tape encryption. Although wire speed encryption is stated in various Decru documents, I accept that encryption will take some finite.

I'm presently working on the these bold assumptions:

(i) For every 2Gb/s of bandwidth entering a FC tape library, one Decru FC520 or equivalent would be about right.

for example, the customer in this case, is using 4 x LTO4 which have 4Gb/s FC attachment. I don't know the details of the fabric attachment at present. It could be just a single 2Gb/s for all I know.

if the customer has two or more FC links into the library, then I would think the multiple port DataFort (FC1020) might be appropriate.

(ii) If redundancy of the encryption path is needed then I will need to double up on DataFort appliances

(iii) Key Management isn't crucial for small local installation (it's done on the appliance?) with local administration tools so the Lifetime Key Manager (LKM) appliance wouldn't be appropriate for a single, local storage to tape encryption path.

I'd be looking for some affirmation that the above isn't wildly wrong for a Decru Datafort Bill of Materials / Quotation for a tape based encryption.

All the best,

Pete

Using 2 lan interfaces??

community@netapp.com — Wed, 18 Feb 2009 15:08:28 GMT

Is it pos sible to use 2 different interfaces for the simulator?

example: Ubuntu: ETH0 Ontap: NS0 LAN

Ubuntu: ETH1 Ontap: NS1 ISCSI

to reflect the reality of our production environment. Actually NS0 and NS1 looks to be intended to test the VIF over the same ETH0 or ETH1 of the Ububtu host.

Can I use SME in my VMware environment?

community@netapp.com — Sat, 08 Mar 2008 18:56:06 GMT

Absolutely!! SME is fully supported on a VMware guest OS. You do however need to use the Microsoft software iSCSI software initiator. That's the one requirement for full support. Support for FC HBAs in a future patch/release of ESX.

SME combined with VMware provides a compelling Exchange solution:

VMware provides server consolidation and quick deployment of virtual machines
SME provides the backup/recovery/high availability for Exchange within the guest OS

NetApp also has SnapManager for Virtual Infrastructure (SMVI). SMVI provides data protection and recovery of virtual machines in a ESX environment. This is a new product from NetApp and one that'll provide great value in a VMware environment. For more info on SMVI, please see the SMVI product page.

So to wrap things up for a virtual Exchange environment, SME is fully supported in a guest OS when using the Microsoft software iSCSI initiator. Future support for FC HBAs is coming in a follow on patch/release. And take a look at SMVI. It's definitely a solution worth looking at.

I am stuck at #5. Even with cifs trace logins on and ldap server logs revved up, when I attempt a CIFS authentication from my mac, nothing happens. No log entries in the LDAP server and no message on the filer console.

Any thoughts ?

How would you compare Netapp's deduplication technology to EMC's Avamar?

community@netapp.com — Fri, 19 Jun 2009 15:30:51 GMT

What are the pros & cons of your technology compared to theirs? We are a small-sized light manufacturing firm with the typical application set of a MS Windows Active Directory based network -- Exchange, MS SQL 2000-2005, Dynamics GP (planning on adding Sharepoint soon). We are evaluting a move from NAS and DAS to a SAN with server virtualization. The majority of the data we backup is file based and we have fairly basic needs for performance with our structured data. What we are hoping to acheive the most on the storage side in order of importance is:

1. Containing the growth of our data

2. Reducing our backup windows and backup costs

3. Improving the granularity of our restores both at the application level and the point in time that we can recover file data back to.

Solaris 10 Zones using Netapp Volumes

community@netapp.com — Sun, 13 Apr 2008 17:35:33 GMT

Hopefully SUN and Netapp will settle their childish squabbles soon...

With the growing scaleability of Sun Servers with CoolThreads Technology (now up to 128 virtual CPUs and 128GB memory) it's inevitable that Solaris Zones will be a common configuration.

So the next logical step is to use shared storage for the Zone data. This will allow for snapshots and snapmirrors of Zones to different hardware and locations...

Has anyone experimented using Netapp for Solaris Zone storage?

Operations Manager 3.8 DeDupe Potential Space Savings

community@netapp.com — Wed, 06 May 2009 21:08:21 GMT

Hi:

With Ops Manager 3.8's Dedupe awareness are there any canned or custom reporting options available to allow a customer to estimate the potential space savings if they were to enable dedupe on a flexvol in an FCP environment?

The only space savings tools I'm aware of are the SSET tools that are run from a Windows or Linux host in a CIFS or NFS environment. I would like to know if Operations Manager 3.8 will be able to perform this functionality for an FCP environment by looking at the storage system. We have over 1,000 SAN hosts with different operating systems, so it would be a nightmare to try to run any host-based tools to estimate our space savings.

Thanks for your help.

Thanks,

Chris

"top" and/or "du" equivalent in API or CLI?

ingo@boxbe.com — Wed, 13 May 2009 07:04:28 GMT

Hi,

is there a way to identify the top-users and/or top-sized directories for a volume or aggregate?

What I am looking for is two functionalities:

1. A command or api like "du" in UNIX, which can summarize and list the directories down to a defined depth

2. A command like "top", which can list and sort the users according to the space their files use on a given volume.

Thanks for any hint, which can guide me into the right direction.

Cheers, Ingo

P.S. Somehow this is done by tools like "TreeSize" - but it would be fine, to have a more performant, integrated way of getting this information.

PPS: Ok, I know, the UNIX-top is about processes and not used space on a hard-drive; so I am searching something which is not a real equivalent but something new, in the idea of "top" but for "top-space-users".

How does VSS on VMHost work with the ESX/NetApp storage?

community@netapp.com — Tue, 24 Mar 2009 17:25:19 GMT

If I want to put Exchange or SQL server onto VMWare hosts. How do I get MS VSS to flush and snap the databases?

Do I need to create luns for each of the databases and manage them from the VM using iSCSI and lose some of the VMotion options or do I create the databases on VMDK and then use something to manage VM's VSS and ESX server to flush and snap.

screening using fpolicy problem

community@netapp.com — Wed, 30 Apr 2008 08:24:28 GMT

screening using fpolicy problem

Gents, when using native file blocking for avoiding mp3 as example i used the folowing code

fpolicy create mp3blocker screen

fpolicy ext inc set mp3blocker mp3

fpolicy options mp3blocker required on

fpolicy monitor set mp3blocker -p cifs,nfs create,rename

fpolicy enable mp3blocker -f

the problem that in this case i lost the control to name "folders"

when i removed attribute "rename" from the line

fpolicy monitor set mp3blocker -p cifs,nfs create,rename

i have the ability again to rename folders but in this case users can create any file and change its extension to mp3 ,

even they will not have the ability to access it after changing its name me as administrator will not be able to delete it.

so my question is how to avoid preventing renaming folders?

Moving MS Windows 2005 Cluster LUNs to another Filer Head

community@netapp.com — Tue, 20 Jan 2009 21:10:45 GMT

Hello,

Well our storage folks have a need to take our filers down and rebuild the aggregates with more random drive selections to increase the performance of our production SQL Server environment. I am the DBA in charge of the OS and SQL Server side of things, and not a storage or NetApp person at all.

We have 2 3070 Filers setup as a cluster pair on the storage side. Currently all of the SQL LUN's and cluster Quorum LUN is on one filer, along with the databases.

We have the ability of rebuilding the aggregates separately on the filer heads.

The idea we came up with was to copy the cluster LUNs from one filer to the other so that we can keep the server cluster up and running while the aggregates are being rebuilt. When that is finished, we plan on leaving the cluster LUNs on filer 1 and only database LUNs on filer 2. The current Windows cluster is only on filer 2 at this time.

Has anyone had to trasfer LUN's like this between filers before? The SQL LUNs are fairly easy to do, it is the Quorum drive that concerns me.

So is there a way of migrating the Quorum drive without having to rebuild the production server?

Thanks!

FAS270c partner will not boot

community@netapp.com — Sun, 13 Sep 2009 11:01:16 GMT

Hi,

I am have issues with a clustered FAS270 with two addtional shelves. It is at a remote site and we've had to power it down several times due to power issues at the site. This last power down, a halt -f was issued on both heads as usual, however upon boot one head came back, the other halted with panic: Permanent errors on all HA mailbox disks (while writing master block) in process fmmbx_instance. Then it halts and goes to the CFE prompt.

When an attempt was made to boot into maintenace mode we get: In a cluster, you MUST ensure that the partner is (and remains) down, or that takeover is manually disabled on the ... FAILURE TO DO SO CAN RESULT IN YOUR FILESYSTEMS BEING DESTROYED

I also recieve errors:

How to: obtain list of IP Addresses shown in "ifconfig -a" via SDK/ONTAP inteface

community@netapp.com — Tue, 09 Sep 2008 21:40:28 GMT

Hello,

I am using the JAVA SDK interface to query our NetApp and I am trying to find out how I can obtain all the IP Addresses on each of the network interfaces. I would have assumed that using the "ipspace" commands would give back the correct information, but it only gives back the interface names, ie e0a and e0b. The only way I can figure to hack this information is to use the iscsi-interface-list-info. But the problem is that one of our Filers does not have an ISCSI license so I can not use that command.

The only way I can see to obtain this information is to cli scrape the data from the "ifconfig -a" command.

Anybody else have a better idea?

Thank you in advance.

Remove Windows Shares

community@netapp.com — Fri, 08 May 2009 12:30:53 GMT

I have a problem with my Storevault S500. It used to be used with Windows Shares and now CIFS doesn't appear to want to work. However, this shouldn't be too much of an issue as I only want to use LUNs from now on. The problem is the Windows Shares are taking up 2TB leaving very little space for anything else, and I don't seem to be able to remove them. Am I missing something?

The Best Multipathing Option for Windows hosts - MPIO or MCS?

community@netapp.com — Tue, 14 Jul 2009 07:47:15 GMT

We predominantly use our NetApp filer for VMware via NFS, so my actual SAN experiences have been rather limited in our setup.

I've recently discovered our consultant who helped me setup a physical Windows host to our NetApp box for SnapDrive and SMSQL functions made a few mistakes.

First, he never had me install the Windows Host Utilities Kit. My understanding is that this needs to be installed in active/active setups to configure the correct timeout settings.

Second, he had me create a nic team with the Intel Proset tools for the dedicated iSCSI nics. Microsoft states link aggregation is not a supported setup with the iscsi software initiator in their initiator user guide. NetApp confirms this in TR-3441.

Our setup is very similar to the multi-network active/active configuration listed in the Fibre Channel and iSCSI Configuration Guide:

https://now.netapp.com/NOW/knowledge/docs/san/fcp_iscsi_config/config_guide_72/setting_up/reference/r_oc_set_iscsi-dualnetwork.html

Since this is purely iSCSI via software initiator, my understanding is that I can use either MCS or MPIO. I'm leaning towards MPIO due to its maturity, popularity, and full support with SnapDrive but am curious for any feedback from others.

What do others consider better for iSCSI with a software initiator -- MPIO or MCS?

Which load balancing policy is the best -- round robin, least queue depth, etc?

TR-3441 mentions least queue depth being the best with the Data Ontap DSM, but I would be using the free Microsoft DSM.

Interestingly, Microsoft's iscsi software initiator guide recommends using MCS if the target supports it and the software initiator is being used. Anyone, care to disagree?

Retention of SnapDrive Snapshots

community@netapp.com — Thu, 25 Jun 2009 21:19:09 GMT

Would anyone know of a way to set a retention policy for snapshots created from the SnapDrive CLI? IHAC who is using Windows Task Scheduler and the sdcli to create daily snapshots and wants to keep two weeks of them, but doesn’t want to have to manually delete the older ones. I’m guessing this would require some scripting logic outside of the sdcli.

Thanks.

SAS Takes Disk Storage to the Next Level

community@netapp.com — Mon, 09 Nov 2009 22:06:35 GMT

SAS disk technology is set to replace FC disks by 2012. The November issue of Tech OnTap includes a question and answer session I had with Doug Coatney of NetApp engineering, who answers questions about SAS and the new NetApp SAS-based disk shelf, the DS4243. This new shelf adheres to the Storage Bridge Bay standard, supports both SAS and SATA disks in HA configurations, and includes new out-of-band management capabilities. You can check out the article at http://www.netapp.com/us/communities/tech-ontap/tot-sas-disk-storage-0911.html <http://www.netapp.com/us/communities/tech-ontap/tot-sas-disk-storage-0911.html>

What are your company’s plans with regard to SAS? Do the features of the DS4243 better meet your disk subsystem requirements?

Restore NFS snapshot file

community@netapp.com — Tue, 12 May 2009 09:41:52 GMT

I'm trying to restore a single file within an NFS vmdk snapshot file.

I've installed Unix services for Windows on my Windows 2003 server and I can connect to the NFS export.

I followed the article on http://blogs.netapp.com/storage_nuts_n_bolts/2008/07/file-level-reco.html to mount a vmdk snapshot,

but have no result.

Also when using UFS Explorer or VMware DiskMount Utilty, the snapshot vmdk file is not recognized.

how to change a value read in?

This may be a silly question, but I'm using the following (no trouble reading from the storage arrays!):

$sm_src = $job->child_get_string("source-location")

Now the value I'm getting back sometimes is fully qualified, and sometimes is not. Can I do the following?

$sm_src =~ s/.netapp.com//;

$job->child_get_string("source-location") = $sm_src;

Or is there a better way to manipulate the values captured from tthe filer? Oh, this is a snapmirror option.

LUN space reservation for VMWARE?

r.thulasiraman@saipem-india.com — Mon, 01 Dec 2008 06:08:11 GMT

Inside a 400 GB flex volume. i have created 2nos 75 GB LUN and mapped with all VMWARE ESX server. In the "volume manage" page i can see 99% as a usage area.

Then I turned off the space reservation of those 2 LUNs .Now the volume usage is showing as 39 % only (Which means 378 GB is available space on 400 GB volume)

.Is it right to turn off the space reserveation for vmware LUNs?

SnapLock aggregates and root volume

community@netapp.com — Tue, 22 Sep 2009 07:00:47 GMT

Hello, all!

Here's a basic definition of SnapLock aggregates and volumes from NOW:

SnapLock is an attribute of the aggregate; therefore, the volume contained in that aggregate inherits the aggregate’s #SnapLock attributes. Every FlexVol volume created in a #SnapLock aggregate is, by definition, a #SnapLock volume. A SnapLock Compliance aggregate contains only #SnapLock Compliance flexible volumes, and a SnapLock Enterprise aggregate contains only SnapLock Enterprise flexible volumes.

I'm wondering if it's at all possible to move the root volume to a new volume on a SnapLock aggregate, since the root volume has to remain free to change/adjust at all times? Even when I make sure my new root volume is a regular one and there are no retention policies active on it, the system still rejects it saying that the new root volume is a SnapLock'd one.

Is there a workaround for this?

Thanx,

Igor

Apple Mac OS X Peformance over CIFS

msourbutts@alphacom.co.uk — Wed, 08 Apr 2009 09:09:37 GMT

Hello there,

Does anyone have any performance stats for Mac OS X using CIFS to connect to NetApp Filers (in particular FAS2050HA).

I have an existing customer who is looking to purchase a FAS2050HA for a 2nd site, that uses a lot of Mac technology. They will initially have around 4TB of data, growing to around 10TB.

The customer is concerned that the FAS2050HA will not be powerful enough to cope with the Mac data and a small VMWare ESX farm using iSCSI.

I can find no performance information that I can use to set the customers mind at rest.

They are currently using a FAS3020HA at another site for a much larger implementation, I just think it is the Mac Integration that is unsettling them a little.

I have read the Integrating with Apple document from the Storevault site, but it is a little old and doesn't really tell me what I need to know.

Any help or advice would be welcomed.

Many Regards

Mark

How to view content of volume snapshot

How do FCoE and iSCSI Fit into Your Storage Strategy?

community@netapp.com — Wed, 24 Jun 2009 19:59:16 GMT

The arrival of FCoE makes it possible to meet all your storage and LAN networking needs with a single Ethernet fabric. However, it may also create some confusion because now you have both iSCSI and FCoE as viable options for Ethernet SANs. In the June issue of Tech OnTap, Silvano Gai of Cisco and Mike McNarmara of NetApp wrote an article that describes the differences between the two protocols with some guidelines for when you might choose one versus the other. They go on to discuss a variety of deployment scenarios and indicate which protocol is most appropriate for each scenario.

You can check out the article at http://www.netapp.com/us/communities/tech-ontap/tot-fcoe-iscsi-0906.html

What are your plans for FCoE? Given a choice, would you opt for FCoE or iSCSI? In what scenarios?

SnapDrive 6.1 Windows with FC RDM LUNs

community@netapp.com — Wed, 09 Sep 2009 20:38:45 GMT

I'm working on an implementation where several SnapManager (SME/SMSQL) products will be running on Windows Virtual Machines. The ESX servers are all FC connected and I've successfully used SnapDrive to create and connect to RDM LUNs inside the guests. Since we'll probably end up with 50 or so RDM LUNs when this thing is all said and done, the customer would like to be able to easily identify the RDM LUNs vs the straight VMWare datastore LUNs. We decided to reserve LUN IDs 0-19 for VMWare datastore formatted LUNs and use 20 and higher for the RDM LUNs. The problem is when using SnapDrive to connect to a LUN, there is no way I've found to change the LUN ID. It automatically just picks the next LUN ID available, which throws a wrench into our naming scheme. What I've been doing instead is creating and attaching the LUN using SnapDrive, then I disconnect and manually remap it on the filer so I can put in my own custom LUN ID. So I have two questions really.

1. Does anyone know of a way to tell SnapDrive either a starting LUN ID or provide it a customized LUN ID when connecting to a LUN?

2. As long as I create and connect the LUN initially using SnapDrive, is there any type of problem with disconnecting it and then doing a manual lun map to that same LUN again? I just don't know if SnapDrive is doing anything special when it connects and mounts a LUN, different than what a normal Windows server would do with a manual rescan and drive mount. I thought as long as I initially create the LUN using SnapDrive I'll have the formatting and alignment issues covered, but I'm not sure if I'm missing anything else that would differentate a SnapDrive mounted LUN vs a manually mounted one.

Thanks in advance

Delete old snapshots

community@netapp.com — Thu, 21 Aug 2008 23:19:37 GMT

This is a quick perl script that utilizes ZAPI to delete any snapshots older than a specified time. It's a somewhat contrived case, but I'm hoping it's a useful template for anyone wanting to get started with the API.

the access on the share.

Please also let me know the ontapi version which has an api for cifs access command, if there is any.

NFS files permissions set to zero.

community@netapp.com — Thu, 21 May 2009 15:09:42 GMT

I have a v3020 device running OnTap 7.2.3 with NFS exporting vol0/etc$ for monitoring purposes. I have started to have problems when I installed CIFS and run the CIFS wizard. My monitoring script stopped working because it couldn't access vol0/etc$ anymore. I did some investigation and I found out that the qtree for vol0/etc$ was set to NTFS. I changed to UNIX (and even MIXED) but I still had problems. In the end I realised that the files permissions for vol0/etc$ were all set to 0. Accessing vol0/etc$ from CIFS works fine but I would like to fix the NFS permissions as they were originally. There are quite a lot of files and I was looking for a quick fix or at least automated.

Many thanks.

VMware ESX 3.5 host can't write to new NFS volume

community@netapp.com — Fri, 20 Mar 2009 14:42:51 GMT

Hi Guys,

Hope someone can help me solve this problem,

I have a VMware 3.5 infrastructure and some ESX hosts using existing NFS volume with no problems,

however, I just had to create a new NFS volume on the same storage FAS 3040, and Export Options setup to allow,

Read-Write, Root and Security.

From ESX hosts I added new volume, and can browse it, however I can't create new folders on that volume, nor create new VMs.

Seems like permissions issue..?

Any ideas?

Thanks,

Oracle Data Management Problems Solved

community@netapp.com — Wed, 25 Feb 2009 00:54:27 GMT

NetApp recently announced the release of SnapManager for Oracle 3.0. In the February issue of Tech OnTap, we described how you can use SMO to significantly improve common Oracle data management operations including backup to primary storage, protecting those backups on secondary storage, recovery, disaster recovery and cloning. Through the SMO interface you can create space-efficient FlexClones on both primary and secondary storage, and you can use clones on secondary storage to better support dev/test, business intelligence and other activities that would otherwise require a full copy of your primary data set. With SMO, you can also delegate responsibility for many of these tasks to DBAs or others in your organization so you don’t have to get involved in every activity that involves storage.

You can check out the article at http://www.netapp.com/us/communities/tech-ontap/tot-smo-0209.html

Have you tried SMO in your Oracle environment? Do the new features of SMO 3.0 make it more appealing?

User with cli or api access to only specified volumes?

community@netapp.com — Mon, 07 Apr 2008 20:47:14 GMT

Is it at all possible to create a user that only has access to manipulate certain volumes. For example I need to create a script that will create and then destroy certain volumes and only those volumes. I'd REALLY prefer not having to give the script access via a user account that has cli-vol* capabilities to all volumes on the filer. I've looked at the api's and you do have finer grain capabilities but I still didn't see an ability to "bind" that user to only certain vols. Am I missing something or is this just not possible?

Thanks for any help.

Cifs shares/Filer Permissions.

community@netapp.com — Fri, 08 May 2009 09:48:52 GMT

Hi...

First post so go easy on me

We have just migrated our file-sharing from a 2k3 server onto a FAS3140 - all is running well after a few teething problems with netbios/dns redirects.

One thing i still need to figure out is administration permissions.. more specifically the ability to take ownership of files and folders. Our desktop services team have to use this reguarly, however by default the only domain-user group on the filer that can do this (a la windows) is "administrators" which also grants full access to the filer, which of course is undesireable.. Is there a specific permission i can add to a group at around "power user" level to allow taking ownership without giving more admin access?

Thanks in advance

disk firmware upgrade (pre-OnTap upgrade)

community@netapp.com — Fri, 20 Mar 2009 00:54:15 GMT

Hello All,

I'm planning an upgrade for our 3020cs to 7.3.1 and want to check my head.

In order to make sure that our disk firmwares are up-to-date and avoid possibility of reboot delay as disk firmwares update during the OnTap upgrade, I am planning get the disk firmware bundle with all the released disk firmwares and stage it onto the filers so that the background disk firmware updates take care of this ("options raid.background_disk_fw_update.enable on")

This should do the trick, correct? I didn't do this last time and had to wait during the change window...I'd like to avoid that if possible this time.

Also, it is my understanding that the backround disk updates are non-disruptive and transparent to users and mounted systems. Is that also correct?

I'm aiming for the nondisruptive upgrade. We have some SATA shelves so I know there is some amount of disruption for those shelves as the shelf firmware updates. I have seen documentation stating "up to 70 seconds" and that has been in line with my observations in the past. Has anybody seen otherwise for shelf firmware updates on SATA shelves?

Thanks in advance for info and opinions!

Regards,

Dan

SME4.0 and remote verification

community@netapp.com — Wed, 28 May 2008 18:51:28 GMT

Hi,

I have had a good read through the documentation and need some guidance.

We have configured a remote verification server as per the SME4 admin guide, however I cannot see how the lun snapshot is presented to the remote verification server(RVS), I think the one key thing that i am missing is adding the iSCSI iqn for the RVS to the initiator group for the exchange server, I can't see anywhere in the docs that implies that this needs adding but can't imagine how it is done without it - it does mention connecting the iSCSI to the filer but goes into no more detail.

Is adding the RVS iqn to the exchange initiator group the way forward? or am i completely missing something?

Best regards

Folders on SnapLock shares cannot be renamed!

community@netapp.com — Wed, 23 Sep 2009 09:41:55 GMT

Hello, people!

When I make a SnapLock volume, open a CIFS share on it and try to create a new folder in it - it's automatically created & called "New Folder" (Windows default) and I cannot rename it!

Sure, I can use qtrees instead, but if there are not retention policies and auto_commit is turned off - folders placed in that share should be accessed, modified and deleted in accordance with user's privileges. Just like with files.

I can access it, delete it, but not modify it.

What's the catch? Why is a folder instantly set to read-only??

Thanx,

Igor

A-SIS de-duplication and deleted data inside VMDKs

community@netapp.com — Mon, 08 Dec 2008 05:52:15 GMT

Hi all,

We're currently using de-duplication on our FAS2050, which is storingng VMDK's for our ESX cluster to access via NFS. It works fantastically well - we're saving approximately 80% space on our "OS disk" volume, and about 50% average across all volumes on our filer.

That being said, I have a question I'm hoping "the experts" can share their insight into.

I was recently trying to figure out why deleting a bunch of data inside one of our VM's didn't translate into the expected reduction in space usage of the VMDK file inside it's FlexVol.

The "answer" I came up follows - I'm hoping someone can "check my logic", and if it's right, perhaps suggest any work-arounds?

Imagine this scenario:

1) NetApp filer:

- storing VMDKs for ESX

- using NFS (I'd think the scenario would be the same with iSCSI / FC LUNs, but NFS is easy and what I'm familiar with)

- de-dupe turned on

- no snapshots - simplifies the example

2) 100GB disk created in VMWare, attached to a Windows VM, and formatted NTFS

- ignore thin provisioning - simplifies the example

- results in 100GB file created on NetApp FlexVol containing almost entirely zeros.

3) A-SIS goes to work

- VMDK de-duplicated

- VMDK's real disk consumption is now (essentially) 0GB - close enough to 100% space saving

4) 50GB of data copied onto disk inside VM

- VMDK's real disk consumption grows to 50GB

5) A-SIS goes to work

- Runs de-dupe pass on VMDK

- let's say data copied onto disk is 50% duplicate

- so real disk consumption is now 25GB (50% of 50GB)

6) All data deleted from the disk inside VM

- Windows deletes data

- But this doesn't actually zero the blocks, just destroys inodes / marks blocks as space as free / etc

- Inside-VM disk consumption now reported as 0GB

7) A-SIS goes to work

- Runs de-dupe pass on VMDK

- But this time the blocks inside the VMDK aren't all zeros - they still contain the old data, they're just flagged as "free" in the NTFS file system

- Therefore de-dupe can't do much (or any) better than the previous pass

- And real disk consumption for the VMDK remains around 25GB

So therefore the real space consumption of a de-duplicated "empty" VMDK with deleted data is far higher than a de-duplicated "empty" VMDK that is a "fresh" disk?

Is that all correct? Or did I miss some big (or small) step in my logic?

Obviously the above is a synthetic - and extreme - example, but assuming I'm correct does this not mean the net savings (inside-VM reported disk usage to real disk usage ratio) from A-SIS will gradually decrease over time as data gets deleted inside a VMDK, and more and more blocks in a VMDK are free-but-not-zero? Assuming, of course, Windows doesn't choose to overwrite the deleted blocks with newer data?

I understand that if I'm correct A-SIS is still just doing it's job - it's the underlying data that gets less de-dupable due to the way NTFS works - but the net result from the user's point of view is you see less and less net space savings from A-SIS over time?

Finally, again assuming this is all correct - is there any way to counteract this effect? Like making Windows actually zero blocks when it deletes them, or something similar?

Thanks,

Matt

Anyway http://www.netapp.com/us/communities/tech-ontap/tot-sas-disk-storage-0911.html is a good read. From a design point of view, what size disks can I use in the new DS4243 shelf and what sort of raid groups should I use for performance or maximum usable capacity?

API doesn't give all Quota-user name

community@netapp.com — Fri, 06 Mar 2009 05:30:59 GMT

Hi,

The api output of quota-report-iter-next doesn't give all the quota-user name. The API output is

<quota-target>nisuser1,nobody</quota-target>
<volume>vol</volume>
<qtree>cifs qtree</qtree>

.....

          <vfiler>vfiler0</vfiler>
                        <quota-users>
                                <quota-user>
                                        <quota-user-type>uid</quota-user-type>
                                        <quota-user-id>519</quota-user-id>
                                        <quota-user-name/>
                                </quota-user>
                                <quota-user>
                                        <quota-user-type>uid</quota-user-type>
                                        <quota-user-id>65535</quota-user-id>
                                        <quota-user-name>nobody</quota-user-name>
                                </quota-user>
                        </quota-users>
                </quota-info>

So if you see the quota-target has two users associated with it but the quota-user section gives just the 'nobody' and the other quota-user section for the user seems to be blank. Can someone tell me why it is so?

Also we have seen that on some filers the quota-target field is empty while the users appear in the quota-user section. Why is the behaviors different?

Multipathing for tape device and load balancing

community@netapp.com — Mon, 06 Jul 2009 03:32:53 GMT

Hi,

I am wondering if multipathing for tape device works in same way as for fisk.

Can someone explain or provide link to any doc or wikid which explains how multipathinng works for tape devices alongwith loadbalancing.

Let me explain one strange thing which I noticed in our environment.

Four tape device connected to a switch blade port 1,2,3, and 4. So lets assume TD1, TD2, TD3, and TD4.

TD1, and TD2 are zoned to fabric F1

TD3, and TD4 are zoned to fabric F2

Filer HBA 4a is member of fabric F1

Filer HBA 4b is member of fabric F2

Now we are able to see either TD1, TD2 or TD3, TD4. Means in some cases TD1, TD2 and in some cases TD3, TD4. Looks whichever ONTAP picks up first shows only those two. If I disable HBA 4a even then I see TD1 and TD2 and /etc/messages file says TD1, and TD2 switched to fabric 2 but TD1 and TD2 are not zoned to fabric F2. So don't know why.

So then I zoned as followes

TD1, and TD2 zoned to both fabric F1 and F2

TD3, and TD4 zoned to both fabric F1 and F2

Now I see all four tape device but all are access either fabric F1 or F2. If I disable one HBA port then all tape devices switched to another HBA but doesn't balance no. of tape device across both HBAs if both are enabled.

So I was wondering for following things.

1/ How to check if tape device have two paths available and which one is primary and alternate, like for disk. i.e. "storage show disk -p"

2/ How load balancing is done for tape devices ? I expect should work based on total no. of tape devices. For disks it works based on total amount of MBs transferred across HBAs and do dynamically.

3/ Why see half of the tape devices if do load balancing at Fabric level and if zoned all tape device to both fabric then why don't ONTAP doesn't do load balancing at its own.

Thanks & Regards,
Raju

Reporting tool for 3020 - on CIFS file share level

community@netapp.com — Wed, 01 Oct 2008 00:32:12 GMT

My customer has 3020 filers which are literally full of unstructured CIFS data. He believes there are lots of unused or stale data - which he wants to report back to the hundreds of owners of these file shares so they can archive them off to tape (yes, the CIFS storage is an under-priced asset - hence its wasted - but a pricing regime of file shares with unstructured data must be combined with reporting)

He wants a reporting tool where he, as a normal user can e.g.

Give me a report of all CIFS file shares (not on a vol or qtree level) which contains min X GB of data that has X% of files not being accessed and/or modfied for the last Y months
Give me a report of all CIFS file shares (not on a vol or qtree level) which contains X% of files of file type extension XYZ which has not been accessed and/or modified within the last Z months
Give me a list of growing file shares (increased more than X GB last Z days)
Etc of reports that can bring storage consumption down
Tool should be able to report a set of standard reports monthly

He accepts a license price for tool and also to sacrifice the self service (e.g. may need SQL skills to customize reports).

Any suggested tools or ways to solve this?

Thanks in advance

problem with disk ownership?

community@netapp.com — Tue, 29 Sep 2009 19:09:19 GMT

I'm working on a Metrocluster (n-series) where I'm having a problem with mirroring the root volume aggregate on one of the nodes.

When mirroring the root volume, I need to take ownership of three of the disks on the other metrocluster node.

However, both nodes claim that one of the disks is a partner disk.

When doing a "disk assign name_of_the_disk -o name_of_the_other_node -f" the console reports "diskown.RescanMessageFailed:warning]: Could not send rescan message to other_node".

Could this be a disk ownership problem? Could it be that disk in question is hardware-owned, and it should be software owned?

Asked

Hi,

I have a NetApp simulator running Ontap 7.2.

As per my observation the following is the behavior of NetApp 7.2.

1. An application registers the machine on which it is running for fpolicy.

2. If the application tries to re-register fpolicy for some reason, the registration fails and surprisingly the existing connection is also terminated.

3. The application should handle this condition and re-register again for fpolicy to make things working.

My application was handling this fine.

But one of our customer reported that in 7.2.3 the behavior seems to be different. In step two the existing connection is NOT terminated. This results in the failure of step 3.

Are these observations correct? Or something is wrong here.

Thanks,

At NetApp, we share in the global responsibility for protecting and preserving our environment today and for future generations by not only creating energy efficient products, but also by practicing good environmental stewardship.

Our approach to fighting growing power consumption is simple: subtract machines and disks from the power equation by using storage more efficiently. This strategy has many corollary benefits: it lowers complexity, people costs, support and service costs, while improving network efficiency and performance. Our eight-point strategy (PDF) for reducing storage power consumption makes use of today’s technology to halt power growth at its source.

Our reduce, reuse, recycle programs include reducing the volume of disposable materials used at our offices; offering each employee a reusable mug made from recycled corn products for daily beverages; and recycling glass, cans, cardboard, electronics, paper, plastic, batteries, and more. These programs have earned NetApp a California Waste Reduction Award Program award.

Through our energy management program, we have successfully reduced energy consumption and improved energy efficiency at our facilities. This effort includes co-generation technologies and participation in the energy demand reduction program with Pacific Gas and Electric Company in California for which we have achieved significant cost savings and recognition for supporting the needs of the community during periods of high electric demand.

Our trip reduction program includes a guaranteed ride home to employees that rely on public transit, telecommuting options, mass transit shuttle programs, reserved carpool parking, and a wide variety of onsite amenities to help reduce the total number of vehicle trips per employee per day.

Help with BCO and SnapVault hosts

community@netapp.com — Fri, 30 Jan 2009 16:59:33 GMT

Here's the generic set of steps I take when trying to get DFM to see and manage SV relationships.

1) Check ndmp on the filers

- on each filer, use 'options ndmp' to verify ndmp is enabled and access is set correctly

- check ndmp credentials on filer(s). Login to the filer as the ndmp user.

2) On the DFM Server, run 'dfm host diag <host>' and make sure snmp, ndmp and hostLogin

all pass. If snmp fails, I check the snmp community setting on the filer and make sure DFM

has that value. If ndmp fails, I set the ndmp credentials for the filer. If hostLogin fails, I set

the login credentials.

dfm host set <filer> hostNDMPLogin=<ndmp-user> hostNDMPPassword=<ndmp-pwd>

dfm host set <filer> hostLogin=<user> hostPassword=<user_pwd>

3) Once 'dfm host diag <host>' shows those three tests passing, I tell DFM the filer is

a SV primary or SV secondary.

dfbm primary host add -U <ndmp-user> -P <ndmp-pwd> <host>

dfbm secondary host add -U <ndmp-user> -P <ndmp-pwd> <host>

4) Then I add the secondary volumes. I usually do this through the WebUI.

DFM Performance Data - limiting scope?

community@netapp.com — Fri, 25 Sep 2009 14:36:14 GMT

Greetings!

We've noted that the folder that DFM/Ops Manager uses for Performance Data (\DFM\Perfdata) is increasing. This appears to be causing some pressure when performing DFM database backups (i.e. the Database backup itself is 3.6 GB, but the backup job needs 10.2 GB to process). This appears to be related to the size of the \perfdata folder (e.g. 13.3 GB)

Is there an option to configure in DFM to limit the history of performance data retained? For example - I'd like to keep only 4-6 weeks of historical performance data for analysis. I didn't really see any configuration options that would allow me to limit the performance data collection in this way.

Thanks in advance for any suggestions or tips!

Xcel To Disclose Climate Change Risks

community@netapp.com — Wed, 03 Sep 2008 22:16:17 GMT

_____________________________________________________________________________

In a first-of-its-kind deal, Xcel Energy (NYSE: XEL), one of the nation's largest power utilities, has agreed to disclose detailed warnings of the risk posed to its business by climate change, according to a New York Times report.

The agreement follows a subpoena by New York attorney general Andrew M. Cuomo, and could have a significant impact on efforts by environmental groups to pressure the energy industry into reducing emissions of the greenhouse gases.

Cuomo used the Martin Act to subpoena Xcel and four other major utilities-- AES Corporation (NYSE: AES), Dominion (NYSE: D), Dynegy (NYSE: DYN) and Peabody Energy (NYSE: BTU). The subpoenas seek to determine whether new coal-fired power plants built by these companies pose risks not disclosed to investors, like future lawsuits or higher costs to comply with possible regulations restricting carbon emissions.

“This landmark agreement sets a new industrywide precedent that will force companies to disclose the true financial risks that climate change poses to their investors,” Mr. Cuomo said in a statement. “Coal-fired power plants can significantly contribute to global warming, and investors have the right to know all the associated risks.”

Environmentalists and investory groups have been pushing companies to analyze the likely effects of current and future legislation on business practices. In doing so, they hope to force the market to accept a larger definition of the "cost" of carbon dioxide emissions, taking into account environmental damage.

Xcel will disclose the financial risks of lawsuits and of federal or state court decisions, as well as “material financial risks” associated with global warming, such as drought--coal plants use vast amounts of water.

“We previously provided detailed information concerning the expected impact of climate change and greenhouse gas emissions regulations on our operations, and under this agreement we will make even more detailed disclosures,” Xcel chairman Richard C. Kelly said. “This agreement will enhance our already aggressive efforts to be responsible environmental stewards.”

Xcel said it plans to build 6,000 megawatts of renewable energy generation by the end of the next decade. The company also said it has reduced greenhouse gases by 18 million tons since 2003.

Create a cifs share inside another cifs share

community@netapp.com — Tue, 15 Sep 2009 20:37:48 GMT

Good Day,

We are in the middle of a migration project from a Windows 2k3 server to a NetApp filer. I have one share that I have copied over and it has another shared folder under it. I cannot seem to be able to share the second folder using Filerview or any other tools. I can create a new shared folder pointing to the folder I want (for example /vol/vol4/P_Drive/Programs/Install/MSOffice2003) but it is a new, empty share. How can I create this share?

Thanks,

john

Is it dangerous to use the SNMP interface?

community@netapp.com — Thu, 20 Aug 2009 12:58:14 GMT

I'm using a Nagios system and the SNMP interface to manage the availability of our NetApp filers. It's working well and I'm happy with that. But a NetApp technician told me that it's dangerous and we will loose all support on NetApp problems as long as this is active.

I can not believe this, because the filer offer this interface. I don't get a statement from NetApp Germany regarding this question.

Is there somewhere a statement or withe paper from NetApp? Has someone made a bad experience with the SNMP interface?

hot removal of shelf

community@netapp.com — Fri, 25 Sep 2009 05:40:48 GMT

Hi,

I know its not supported to hot remove shelves but I need to qualify something. Is it still not supported if ALL the disks on that shelf are spares only, so they

are not part of a RAID group/aggr. etc. Would it not simply be a case of taking the adapter down over CLI and remove it?

I also see negative numbers in some of the other api calls. If you run the above command, do you also see negative numbers? Any ideas. Ive tried this on RH3, RH4, 32bit, 64bit.

As a second issue, the <volumes> section is not being split out into a stanza for each volume so can not be parsed with the typical foreach loop. Is this a bug in the API.

Thanks for any help.

vol destroy and snap delete takes time to return space to aggr

community@netapp.com — Fri, 07 Mar 2008 08:57:15 GMT

haritha.n

on 4/12/07

Asked

The volume destruction or snap delete actions does not return the space

occupied immediately. It takes a while to reclaim the the space occupied by

the volume.

This can be reproduced by creating a big volume on a aggr. Then destroy the

volume using vol destroy command. Keep checking for the available space for

the aggr. It keeps on increasing with time.

After aome time the whole space occupied by the volume is returned to the

aggr as available space.

Also if the volume has large amount of data it takes more time to reclaim

space after executing the vol destroy command.

This delay in space reclaim can cause failures in the applications when we

have some vol creation and space guarantee operations/actions immediately

after the vol destroy action.

Is there any other way out to get the right information immediately rather than sleep for few seconds before checking on the df ?

Is RAID-4 on 2 disks a RAID-1 in fact?

community@netapp.com — Sun, 04 Oct 2009 20:12:04 GMT

I have a questin to DataONTAP experts.

I can create a RAID-4 configuration on 2 disks (aggr create -t raid4 -r 2).

How do you think, is it RAID-1 in fact?

PS.

I know, the difference between RAID-1 (mirror level) and RAID-4 (parity level), but I don't know how RAID-4 works on 2 disks.

Thank you.

Tech execs: Green datacentres are crucial

Energy efficiency has always been a serious consideration of the tech industry. But executives from Cisco Systems and IBM in California on Tuesday said it has become crucial as their customers are aware of rising energy costs.

One of their key areas of focus is the datacentre. Power usage related to datacentres doubled from 2000 to 2006 to comprise about 1.5 percent of the energy Americans use annually, according to the Environmental Protection Agency. Silicon Valley Leadership Group president Carl Guardino said if the growth continues as expected, US companies will need 10 more power plants to generate their added electricity by 2012.

That's why tech executives are examining new ways to design datacentres and improve existing ones.

"Energy costs rank right after labour costs for our customers who run large datacentres," Nikhil Jayaram, Cisco's director of engineering in the mid-range router group, said while speaking on a panel about green IT.

"Cisco's now moved to a new era where we're really focusing on power. Before it was performance, performance, performance, and cost was the fourth concern," he said.

J Antonio Carballo, a partner in IBM's venture capital group, said on the panel his investment focus is "all about energy efficiency", especially in datacentres. His group teams up with external investors and start-ups to focus on power and efficiency in the US and China. He said that in China he's seeing power at the centre of 100 percent of designs.

Still, he said, there are gaps in the energy system design in tech and semiconductor conductor industries as a whole. He said he would like to see adaptive systems that can monitor and shift energy distribution as needed. "It is the case where we have to develop internally some system monitoring tools," Carballo said.

Cisco's Jayaram said his company is also teaming up with coalitions such as the Green Grid to advance energy efficiency in datacentres. Cisco is particularly concerned with improving the energy usage of existing datacentres that will be in operation for years to come. But for future tech, it is examining uses of virtualisation software, or software to run multiple applications on a single computer instead of two parallel systems, he said.

Power has long been an element of the electronic design industry, but what's new in the last 10 years is a need "for power and energy to be looked at from a more holistic perspective", said Ted Vucurevich, chief technology officer at Cadence.

To that end, he talked about a so-called grid 2.0, or a system to distribute energy generation in a way that would be adaptive and efficient. Google chief executive Eric Schmidt touched on a similar idea on Monday night in a talk about his company's energy plan.

Jan Rabaey, a professor in the department of electrical engineering and computer sciences at the University of California at Berkeley, said that he's been in power design since the late 1980s. The good news, he said, is that the industry has made much progress; the bad news is that it's still a problem. He said the low-hanging fruit of this issue is to make more information available to companies and consumers about their energy usage, and that will change consumption.

"Most consumers don't know what their primary source of energy consumption is. Once you have information, then you have room to start addressing things as inefficiencies," Rabaey.

Why is NetCache appliance (NetApp/6.1.1D8) redirecting an HTTP POST with a 302?

community@netapp.com — Sun, 15 Mar 2009 06:05:50 GMT

Hi folks -- I am trying to track down something that I have found NetCache appliance (NetApp/6.1.1D8) is the root of.

Certain people -- all in South Africa, for some reason -- are trying to access my website by filling out a form, which is supposed to submit with an HTTP POST.

However, they appear to have NetCache/NetApp installed, and it is oh-so-unhelpfully getting in the way, and converting the POST into a useless GET. The contents of the POST are gone, and the result is just an error page.

I understand what proxies are supposed to do, but how in the world can this possibly work? A POST is meant to change data, and by returning a 302 redirect, it's just not going to work.

I have the transcript of a test connection that a user experiencing the problem was helpful enough to provide.

Is this something that has been fixed -- that maybe the person's ISP needs to upgrade?

Performance Sizing for Large Sequential Operation

community@netapp.com — Wed, 13 May 2009 02:03:45 GMT

We do know that per 10K FC disk will yield ~100 IOPS. If a customer requires 1000 IOPS, we will just size it with 10 data disks, but that's for small random ops. What if a user requires 100MB/s of large sequential operation? Is there a rule to say how much throughput will a FC or SATA disk generate?

Hello,

1. Attached is a zip-file (you must rename it to .zip) containing a Visual Studio 6 - project based on your Hello-Ontapi-example . When I run the program here, some of the childnodes are empty (e.g. size free, size-used), others are returning strange values (e.g. 16,384,000 GB for size-nominal). First I thought I was doing something wrong with the casting, but on aggr-list-info it is working.

2. Because of the lack of a na_child_get_int64()-method I would also like to know how I can cast the string most efficiently to an unsigned 64-bit integer with c++.

How to find out hosting filer name for a given vfiler name

community@netapp.com — Mon, 13 Apr 2009 03:31:09 GMT

NOTE : Something wrong with this page as body of discussion missed in my discussion so trying to put again.

Lets assume there is a big NetApp infrastructure with lots of vfiler setup as well but there is no Operation Manager setup though ssh to vfiler is configured.

Now if any user complain about some issue at any vfiler as user always sees vfiler then how would you find out vfiler's hosting filer name given no OM setup there.

Anybody have any idea other then OM to find out vfiler's hosting filer name if ssh to vfiler is configured.

PS : There is no straight forward command at vfiler level to find out its hosting filer name and I feel that should be there as a quick check.

Using Widelinks in a CIFS environment

community@netapp.com — Thu, 23 Apr 2009 18:11:34 GMT

Has anyone ever setup Widelinks in a CIFS only environment?

We have a FAS 3070 cluster, and I'm trying to re-direct users from a volume on one head to a volume on a different head (or possibly even on the same head). I was able to do this using NFS, but our NFS license was temporary, so to create any new ones, I need to do it using CIFS only.

I've read through the following documents, but they have been no help:

About Widlinks Entries: http://now.netapp.com/NOW/knowledge/docs/ontap/rel723/html/ontap/filesag/7multi53.htm

Definitive Guide to Setting up Widelinks (that's debatable): https://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb7368

A more detailed explanation of what I'm trying to do:

We have several large file systems, over 2 TB each. The users need to be able to go to a single directory within an already established DFS root (which I'll call \\Domain.com\DFSRoot) and see each of these file systems as a subdirectory of that single directory. So, I've created a DFS link within the DFS root... we'll call it TopDirectory that points to a CIFS share/volume on Filer A with the same name. Using NFS, I had to mount that directory to a Unix machine along with all the volumes I wanted to appear as a subdirectory (I'll call them Volume01 - Volume10, and they each reside on Filer B). From the Unix machine, I then ran the command ln -s /mnt/Volume01 /mnt/TopDirectory/Volume01 for each of the volumes that I want to appear as subdirectories. This created a symbolic link for each of the directories within the TopDirectory volume.

Then I had to edit the /etc/symlinks.translations file on Filer A so that the symbolic links would point to a share on Filer B. So, the entries would look like this:

Widelink /mnt/Volume01/* \\FilerB\Volume01\*

Widelink /mnt/Volume02/* #\\FilerB\Volume02 #*\

Widelink /mnt/Volume03/* \\FilerB\Volume03\*

Widelink /mnt/Volume04/* \\FilerB\Volume04\*

Widelink /mnt/Volume05/* \\FilerB\Volume05\*

Widelink /mnt/Volume06/* \\FilerB\Volume06\*

Widelink /mnt/Volume07/* \\FilerB\Volume07\*

Widelink /mnt/Volume08/* \\FilerB\Volume08\*

Widelink /mnt/Volume09/* \\FilerB\Volume09\*

Widelink /mnt/Volume10/* \\FilerB\Volume10\*

This works as advertised. When I go through DFS to \\Domain.com\DFSRoot\TopDirectory I see all ten directories and can go into them to see their contents.

My question now is, how can I create the symbolic links if I don't have an NFS license? I've been told that I can use ln.exe to create them, but I can't get it to work. The copy of ln.exe that I have was apparently created by NetApp, but their help desk says they do not support it. Apparently there is a version that came with Windows Resource Kit, but I think it was an older version. I think it was replaced with linkd.exe, which I've tried, but I can't get that to work either. I've tested linkd by creating a link on windows server to a different directory, but if I try to use a UNC path, it fails.

Can anyone tell me how to do this, or if it can even be done?

Thanks!
