Where do I find information on the NetApp SNMP MIBs and supported Data ONTAP versions?

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?

ONTAPI version must be at least 1.7 to use vfiler tunneling feature

community@netapp.com — Tue, 17 Nov 2009 19:28:53 GMT

I am trying to use the Manage ONTAP SDK 3.5.1 (.NET/PowerShell) but I am having trouble using the NaServer.SetVfilerTunneling feature.

PS C:\> $NaServer = TransportType='HTTPS'

PS C:\> $NaServer.SetAdminUser("root","password")

PS C:\> $NaServer.SetVfilerTunneling('vfilername')

system-get-ontapi-version reports API 1.9, so I don't know why it is working. Any suggestions?

SANOWN not enabled

community@netapp.com — Mon, 10 Nov 2008 13:53:22 GMT

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 .

Thanks

OnTap version 7.3.2 - When Volume is 100% capacity - NaAPIFailedException: Unable to create iterator (errno=13001) occurrs

community@netapp.com — Thu, 12 Nov 2009 21:52:13 GMT

We noticed that when we were monitoring our NetApp (trying to read the CIFS Shares via the iteration method), we started to get errors. We believe it is because a volume is at 100% of capacity. If we allocate more space to it then the error goes away. We do not experience this on 7.2.5.1

Caused by: netapp.manage.NaAPIFailedException: Unable to create iterator (errno=13001)
at netapp.manage.NaServer.invokeElem(NaServer.java:670)

Any help would be appreciated.

Thank you,

Michael

Math behind snapshot-volume-info -> size-available

ingo@boxbe.com — Tue, 10 Nov 2009 17:39:25 GMT

Hi all,

I am wondering what exactly does the value of size-available from the API snapshot-volume-info tell us? The SDK-documenation says:

Total bytes that when exhausted will disable us from taking snapshots. If this value is 0, snapshots cannot be taken. Any other value would allow us to take a reliable snapshot. This space may or may not get exhausted by taking a snapshot. Also it may get used by writes/allocations in the volume. This is not equal to the free space in the active file system or anyway related to the size of the next snapshot.

So in which way is this value different from the free space?

What I have learned from the discussions: It seems to be queried before someone takes a snapshot. Is this true? Are there any other or better uses for this value? May it be interesting to monitor this value?

Thanks for your comments, Ingo

Quota report in vfiler with SDK API.

community@netapp.com — Fri, 06 Nov 2009 10:02:44 GMT

Hi,

I'm trying to understand the SDK so that we can use it to get info from quota in our vfilers.

The thing is that I can't try it out on the simulator, beq it requires licenses for vfiler support.

And I don't want to play to much with our production environment

Is there a way to get quota report from a qtree in a vfiler in the SDK?

We use hard disk quotas to, well, to quota our old "disks" that is migrated from our old windows fileservers.

And now we can't see the growth on a single qtree anymore..

Perhaps I'm going around the lake to get to the water here?

Any ideas?

Dedup output in System Manager

community@netapp.com — Sun, 10 May 2009 04:53:24 GMT

I very much appreciate having deduplication capability in System Manager -- there's a bit of the reporting that seems quirky though.

When I look at a "df -sh" output, I can see the "saved" space per volume -- I can't seem to find this anywhere in NSM though.
NSM does have the "Space Saved" percentage but it's located under the "Last Run" section which is rather confusing (especially given that the Space Saved number there only refers to the amount of space saved during the last dedup run).

Thoughts? Am I missing something obvious?

By the way, I used System Manager at a customer site last week -- is very solid and the customer really liked (I offered them the choice between FilerView and NSM (noting the version 1.0 aspect) and they chose to tryout NSM....very positive results so far).

SnapDrive and Prot Mgr

community@netapp.com — Thu, 05 Nov 2009 14:06:06 GMT

I'd like to use snapdrive to create a snapshot of a lun, then be able to call Protection Manager to do a backup (snapvault) of the storage system.

How can I tell Prot Mgr to grab the specific snapshot that snapdrive created?

In my environment I'm using SDW6.1, PM 3.8. If I need to upgrade to SDW6.2 or PM 4.0 that's fine, I can wait, as long as this feature will be in the software.

I know this is possible since the SMSQL, SME and SMO all do this, but I just don't know the mechanism. Also in looking through the Managability SDK I didn't see any calls.

Thanks,

Andy

How to view content of volume snapshot

community@netapp.com — Thu, 29 Oct 2009 18:52:57 GMT

When using SnapDrive, user can mount a snapshot of a LUN as a temp disk, view and copy its content out.

Is it possible to do the same thing via a tool or ONTAP API for volume snapshot? (not related to LUN)

Also, back in SnapDrive 4.1.2, it can connect to filer CIFS share as LUNs, how does it handle the same thing?

Thanks a lot in advance!
