Operations Manager / Backup Manager.

Greetings,

We have a 3.8 version of OM/DFM that has been managing backups from
multiple sites to a NearStore. We just moved the shelves to a
different NearStore yesterday due to disk count limitations.
Everything went well except OM will not recognize the new destination
for the relationships.

A snapvault status on the secondary shows all the relationships and
the aggregates and volumes are online. We did a snapvault start -S of
the relationships, a snapvault update, and also a snapvault release on
the primaries. The primaries all show the correct relationships.

OM can see the new destination filer and all the volumes, so it has
access. It has also figured out the original NearStore volumes and
relationships are not there because it removed them, and also emptied
the schedules of any backup relationships.

We tried a "Add new backup" which seemed to have worked except it did
an Initialize of the relationship according to the snapmirror log file
and seems to have done a baseline. We cannot re-baseline all of these
relationships.

Does anyone know how to get these relationships into OM without having
to do a new baseline?

Thanks,

Jeff

RE: Operations Manager / Backup Manager. [In reply to]

Protection Manager has wizard to import existing SnapVault relationship; did you try it?

Otherwise these KB articles give example how to re-import existing relationship after source change; may be the same technique works in case of destination change as well?

Re: Operations Manager / Backup Manager. [In reply to]

Andrey,

Unfortunately these are not helping.

We are using Backup Manger in Operations Manager, and not Protection
Manager. We already know that whatever is done in PM won't be seen by
OM or from the CLI. That is one of the reasons we don't want to use
PM.

I ran "dfbm primary dir add <destinationfiler>:/sv_vldummy
sourcefiler:/vldummy/test" This will show the volume as a primary for
the destination volume. The entry will disappear about an hour later.

I can still do a manual snapvault update, but the relationships in DFM
go away including the schedules, so no snapshots are getting created
after the transfer.

The dfmcmd.log shows the job to create it running, the gui shows the
job completed, but later the svmon shows it was deleted. It doesn't
say why. There are other entries about backupSources tables but I
can't figure out what it means.

There are a few relationships that still work, but we don't know why
they survive and still show up while most of the others fail.

Any ideas would be appreciated.

Thanks,

Jeff

RE: Operations Manager / Backup Manager. [In reply to]

As a wild guess - Backup Manager is using NDMP to discover relationships. You did enable NDMP on new secondary and configured NDMP credentials in Backup Manager?

Re: Operations Manager / Backup Manager. [In reply to]

Did you do a "dfbm primary dir relinquish <primary-directories>..."
first? That will release these relationships from the OM database.
Then you rediscover the relationships on the new NearStore and
finally use the dfbm primary dir add to re-add them back to the
datasets as needed.

Also make sure you stop the reaper process first
dfm option set dpReaperCleanupMode Never

hope that helps

Re: Operations Manager / Backup Manager. [In reply to]

Sto,

I think I may have them all functioning at this point in time. It has
been ~10 hours since the last time I added them and they are still
here. Hopefully they will stay put. Just for the record, here is
what appears to have worked. Maybe I'll be able to find it in 4 years
when I need it again :-)

1. The physical move of the disk shelves brought the snapvault
relationship information with them. A snapvault status showed that
without having to do anything after changing ownership of the disks
and bringing the aggregates online.

2. I did a snapvault start -S <primary dir> <secondary dir> to update
the relationship. This showed on the clients in a snapvault
destinations output.

3. I did the dfbm secondary volume add of all the destination volumes.

4. I did the dfbm primary dir add of all the primary qtrees.

5. I ran a snapvault update from the command line which may not have
been needed.

6. I did a "Back up now" of each primary directory from the Backup
tab. I think this may be what locked everything in and kept them from
disappearing.

I still need to do a snapvault release on all the clients to remove
the relationship to the prior NearStore. Hopefully this will fix
things and we'll be good to go.

Thanks Andrey and Sto for the help and suggestions.

Jeff
