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 ?

ISCSI

Like above

[root@oraclesrv mnt]# dd if=/dev/zero of=/dev/sda bs=5M count=1000 conv=notrunc

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,

I am seeing Access violations for OM Database Backups

I was however able to set schedule and take archive backups with dfm backup cli.

Also the dfm user cannot login with login ,but works with setup->Administrative Users link ,

Could this be any Domain Authentication/Security Issue ?

Thanks

Aggregate space

Is there a best practice for the amount of free space to be left within an aggregate?

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!

Release date for SMO 3.0.3?

SMO cloning of Oracle database on an alternate host ?

community@netapp.com — Wed, 03 Jun 2009 20:53:56 GMT

i would like to have feedback from someone who performed SMO cloning for Oracle database (9i or 10g) on NFS protocol:

here is the use case:

A) install SMO on two AIX hosts : AIX 1 and AIX 2
B) create a clone with SMO 2.2 from a database that is running on AIX1 and then request SMO to mount the clone (all NFS mounts from qtrees) on AIX2
C) start the cloned database on AIX2

in this case, how can we start automtically the Oracle database on AIX 2 ? Does someone perform scripting for that case.

according to information i have , SMO will only mount NFS qtree on AIX2 from the clone but will not start and recover the Oracle Database in the clone

besides, SMO will not modifiy the TNSNAMES file and maybe other ORacle files.

any help is welcome.

SMO - Mirroring data subsets

community@netapp.com — Thu, 09 Jul 2009 09:03:21 GMT

Is there any way using SMO to run some sort of SQL script to limot the data mirrored to a date range?

Or another fancy way of doing this that avoids old school Oracle scripting?

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

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

Dave

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!

Marc
