OM & Provisioning Mgr don't display volumes as belonging to vfiler

[smurphy]

When I run "vfiler status -r <vfiler>" on a storage controller, I show 5 volumes listed as resources belonging to that vfiler.  In both OM & Prov Mgr one of the volumes is listed as belonging to the hosting storage controller.  What do I need to to get OM & Prov Mgr to correctly display the volume as belonging to the vfiler?

Hi,

Was the volume moved to vfiler recently?

Can you run a "dfm host discover <hosting-storage-system-ip-or-name>" & then recheck after a few mniutes.

Hi Sean

For Operations Manager to properly discover volumes belonging to a vFiler unit please ensure the following

- Login credentials of storage controller are set in DFM

You can use the following command

dfm host set

- The vfiler monitoring interval is by default 1 hour

- After the monitor is run check the volume ownership in Operations Manager

The storage controller credentials are correct. I added the volume to the vfiler using the CLI over 24 hours before posting this and the vfiler monitoring interval is at the default 1 hour. I specifically issued "dfm host discover " to refresh the items several times yesterday as well as this morning.

Hi Sean

Do you see any errors in dfmmonitor.log

You can also see "dfm about" and just check if 10% free space is available for monitors to run

Hi Sean,

Do you see any ERROR messages in dfmmonitor.log?

Regards,

There is sufficient free space for monitoring.

The only errors that exist are due to having recreated the dataset a couple of times. Since using the CLI to remove then add the volume back into to the vfiler, there have been no entries in the dfmmonitor.log filer (including the remove/add just described).

Just to confirm the steps

1. There were 5 volumes in the vfiler unit

2. These were discovered fine by Ops Mgr

3. One of volume were removed from the vFiler unit from the storage controller CLI

4. This volume was shown in OpsMgr as belonging to the storage controller

5. This volume was added back to the vfiler unit in the storage controller

6. There is problem in getting this particular volume discovered as part of vFiler in Ops Mgr after the volume is added back

[smurphy]

1. Yes 5 volumes

2. All were initially added via NMC/Provisioning Manager

3. The volume in question was initially removed by deleting the dataset with the physical volume still attached. Removed initially due to issues creating more than 15 qtrees. This limitation was resolved. The volume was then re-added via Provisioning Manager, however it showed that the physical storage was now the hosting filer. Vfiler status -r showed the volume correctly owned by the vfiler.

4. I removed the volume from the vfiler via the CLI, then waited.

5. I re-added the volume to the vfiler via the CLI.

6. Correct, OpsMgr only shows the volume to be owned by physical filer.

Hi Sean,

     I tried your secnario and even after multiple retries, i couldn't reproduce it.

The following are the steps i tried. Kindly reply if I missed out something or misunderstood anything.

1. A dataset NTN1 with 1 volume NTN1:/NTN1and 15 Qtrees. The vol resides on a vfiler NTN1.

2. Vfiler NTN1 has 4 more volumesi i.e. total 5 ( excluding the root volume)

3. The dataset NTN1 is now deleted using NMC/Prov Mgr. Now deleting detaset doesn't delete any volumes. So my vfiler NTN1 still has all 5 volumes.
