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.

Sent by: "ADSM: Dist Stor Manager" <[email protected]> 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.
