Re: [ADSM-L] What does volume status of OFFLINE mean/do?

If it helps, we have taken random volumes off-line when an array restart was 
required.  We also had our AIX admin unmount the volumes.  Once the array was 
on-line we reversed the changes and all was good.
If possible test it, we last did this with TSM 5.3 and probably AIX 5.1.
Expect many alerts if TSM is running a process that needs data from the 
off-line volumes.

Thanks.  That pretty much confirms that OFFLINE is useless to me since I
don't want to loose the data, if at all possible.  19TB is a lot to
restore from dozens of offsite tapes.

Zoltan,

Update volume wherestatus=offline would mean to do something to volumes
that have a status of offline. I'd think you would have to use

update volume * access=unavailable wherestgpool=<SANSTGVOLUMEPOOL>
wherestatus=offline

Output from help update volume:

  UNAVailable
       Specifies that neither client nodes nor server processes can
       access files stored on the volume.
       Before making a random access volume unavailable, you must vary
       the volume offline. After you make a random access volume
       unavailable, you cannot vary the volume online.
       If you make a sequential access volume unavailable, the server
       does not attempt to mount the volume.
       If the volume being updated is an empty scratch volume that had an
       access mode of offsite, the server deletes the volume from the
       database.
Cheers,

Rick
