How to change Model in 31xx frame

community@netapp.com — Wed, 11 Nov 2009 09:06:10 GMT

Hi,

I would like to change the personality of a 3140 frame to a 3170, because we internally streched a 3170 to metro cluster. We had only a empty 3140 frame left for the second head, but the 3170 in the 3140 frame still shows up as 3140.

I know the 3170 works great in the 3140 frame. But If you want to show a failover to a customer, he sees 3140 and 3170 in one cluster

If we have any internal chance to change the personality from frames, I would be happy to know how.

Greetings,

Stefan

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.

Dedupe message from OM 3.8

community@netapp.com — Thu, 12 Nov 2009 02:55:36 GMT

Hi,

Im getting this from our new OM server:

Overdeduplication level of the volume Condition Over deduplication percentage ( 208.26% ) of the volume exceeds the

over deduplicated threshold ( 130.00% ). Increase the threshold or resize the volume.

looking at it I get even more confused:

SIS savings

FAS608001B> df -sg VMWARE_DEV_VOL008

Filesystem used saved %saved

/vol/VMWARE_DEV_VOL008/ 169GB 392GB 70%

Vol size

FAS608001B> df -g VMWARE_DEV_VOL008

Filesystem total used avail capacity

/vol/VMWARE_DEV_VOL008/ 270GB 169GB 100GB 63%

/vol/VMWARE_DEV_VOL008/.snapshot 0GB 61GB 0GB ---%

So we have saved 392GB and my total vol size is 270GB?? how does that work?

Shelf firmware upgrade in cluster

community@netapp.com — Fri, 13 Nov 2009 11:52:28 GMT

We plan a AT-FCX shelf firmware upgrade from version 34 to 38

The environment is a cluster of FAS3050c - Ontap 7.2 (yes i know)

I would like to double check some things with what I read in the documentation:

"Do not use the nondisruptive method (that is, using the cf takeover and cf giveback commands) to update disk shelf firmware. Doing so will prevent access to data on disk shelves for a much longer period than using the storage download shelf command."

Does it mean no automatic takeover is needed nor it will initiate on its own on shelf timeout?

Process will go this way (correct me if i am wong):

download of file to location /etc/shelf_fw
priv set
storage download shelf (to confirm press y)
(70 seconds timeout PER shelf + no automatic takeover initiating)
priv set
sysconfig -v

Panic with SMB signing enabled. 7.3

community@netapp.com — Tue, 22 Sep 2009 11:01:37 GMT

Hi Folks,

We have a customer with a FAS3020 Cluster running Cifs on one node and Exchange over ISCSI on the second node.

All has been well for a long time till SMB signing was turned on.... and no its not SMB 2.0

The Filer is running DOT 7.3 since last October 2008 with no issues. We have been looking to upgrade but it hasn’t happened yet.

The following SMB errors have been noted on the console but I cant find much info on them.... any ides very welcome.

CIFS: Request from client 10.112.xxx.xxx for operation 43 (echo) was rejected because the client requested enforcement of security signatures (SMB signing) and the signature provided by the client did not match the value calculated by the filer.

Then the bad bit... PANIC Cluster takeover.....

Panic Message:

process on cpu0 hung (OffloadWorker05) for 6010 milliseconds! in process

idle_thread1 on release NetApp Release 7.3

I do fully intend to upgrade to 7.3.1.1L1 but I would like to understand what’s going on...

Any ideas or ramblings are much appreciated.

Q: Is it safe to delete the default /vol/vfiler_volume/home directory?

community@netapp.com — Fri, 16 Oct 2009 19:40:53 GMT

Hi,

We are trying to build a functional way of using qtrees and quotas.
And one of the quotas should be in the home qtree.
But beq. the default share/directory /vol/vfiler_volume/home is there I can't create the qtree.

I've searched high and low but haven't found anything about that.
Is it safe to delete the ./home and create a qtree there instead?

Regards Falk

SnapMirrored Lun in V-Sphere..... VM's fail to start up

community@netapp.com — Wed, 30 Sep 2009 10:59:10 GMT

We are currently doing a POC for NetApp Storage hosting V-Sphere. We are snapmirroring a Datastore to a DR FAS3020 and this all seems fine. We can suscessfully mount the Dr volume on the DR VmWare servers and add them to the inventory in VC but when we try and start the VM's we get the below error..... I have done this many times in ESX3.5 with no issues....

The systemId does not match the current system or the deviceId and vendorId do not match the device currently at 007:08.0

Any Ideas much apprecated

Thanks

Michael.

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?

community@netapp.com — Fri, 18 Sep 2009 07:45:35 GMT

Netapp had pressed new DS4243 disk shelf. It support 24bay SAS/SATA drives. I have some Dell SAS 300G disks. Can I use these disks in DS4243?

How to check individual qtree sizes within a volume

community@netapp.com — Mon, 03 Aug 2009 19:58:43 GMT

Hello Folks,

I am trying to automate storage utilization for a CRM based tool. I am stuck at a point wherein I need to input individual qtree sizes for each volume to another script. Could you please help me out with an Ontap command that could fetch me individual qtree sizes (unix/ntfs style) from a volume containing it.

Many Thanks in advance!!

Dhiman.

Four FAS2050 controllers - variants of connections?

community@netapp.com — Mon, 17 Aug 2009 10:20:11 GMT

E.g. I have 4 FAS2050 controllers - how can I connect them?

Is it possible to make 4-nodes cluster? or maybe Can I make 2 pair of active-active cluster

and set up between pairs an active-passive cluster?
