How do I delete old relationships in DFM?


Hi there,

I have a few datasets with old relationships in them, they look just like the ones that are active in there, but the lag time is not the same, and they are not updated when the SnapManager triggers a backup (oh, they are SnapManager datasets)

The DFM version is 5.1

If I do a manual "Protect Now" it updates all 5 relationships...

When I edit the dataset, and look at the primary volumes, they only show 3 volumes...

And 3 destinations...

So clearly something is wrong here...  dataset shows 5 relationships, but only 3 are defined...

Here are some extracts from the cmd...

The dataset...

I suspect the two first relations "3338" and "3339" but I'm not sure

There are also a few orphans which is visible with the dfpm relationship list -ax...  (sorry about the formatting)

From this you can see that I did some migration of volumes from one aggr to another to spread the load on the aggrs...  so there are some orphan snapmirror relationships... apparently nothing is ever deleted from DFM

I can asure you that both the volumes and snapmirror relations are gone.

ok, now on to the filer to have a look...  this is the destination..  only shows 3 relationships...

filer-dk11> snapvault status

Snapvault is ON.

And on the source we also see only 3 relationships...

filer-dk1> snapvault status

Snapvault primary is ON.

filer-dk1:/vol/ERP01_SNAPINFO/qt              filer-dk11:/vol/sv_ERP01_SNAPINFO/qt                             Source         00:38:44   Idle

OK I have cut the other snapvault relations away as they are not relevant, but rest assured that there are only these in relation to the dataset..

Now I would very much like a description on how to remove the right relationship from my dataset, firstly how to findout which ones is the "faulty" ones, and how I can remove them from the dataset...

I have tried to fiddle arround with the dfpm dataset remove...  which didn't bring much luck...

C:\Documents and Settings\adminogr>dfpm dataset remove 1460 3339

Error: There is no volume, qtree, directory, host, aggregate or virtualization object named '3339'.

Also the relinquish returns an error:

C:\Documents and Settings\adminogr>dfpm dataset relinquish 3338

Error: Could not find volume or qtree '3338'. Reason: There is no host, aggregate, volume, qtree, resource group, or dataset named 3338.

Hopefully somone has the magic command to fix this mess ? 🙂




This can be sorted out but I recommend that you open a support case to work through it.

Some of the items to discuss/confirm under the support case:

1) Was the Secondary Space Migration Wizard used to migrate the volumes or were primary volumes migrated?

2) Assuming that the old aggregates/volumes for the migrated relationships were destroyed then purging the aggregate or volume from the UM database will remove them from any dataset they are a member of.  Prior to any purging work it is necessary to confirm that a valid UM db backup exists .

3) Another concern that comes in with application datasets for Snapmanager integration is that the Snapmanager product needs to be aware of the relationships so that it can continue to update them during backup jobs. It sounds like it might still be operating correctly here, but I recommend that the Snapmanager configuration wizard (assuming SMSQL based on the names) be run through to update the configuration if it needs it. If no changes are needed, then continue through and finish it.
