Look for msgno=8469 and see if the dismounts have been failing. I get this kind of behavior occasionally and have found that the dismount fails (hardware problem) and TSM transiently reports volumes unavailable.
Henk ten Have <[EMAIL PROTECTED] To: [EMAIL PROTECTED] > cc: Sent by: Subject: TSM server problem "ADSM: Dist Stor Manager" <[EMAIL PROTECTED] IST.EDU> 06/20/2002 10:17 AM Please respond to "ADSM: Dist Stor Manager" I couldn't find an APAR that describes what we have been seeing on our 4.2.1.11 (AIX 4.3.3) server during the last few weeks so I was wondering if we have discovered new bug. First we got this message in the activity log: 06/09/02 10:39:38 ANR1229W Volume 000591 cannot be backed up - volume is offline or access mode is "unavailable" or "destroyed". We did a 'q vol f=d'. The access mode of the volume was 'Available' so we dismissed it as a freak incident until the message repeated itself the next day. This time we opened the (3494) library and verified that the volume was in the correct cell. We tried a 'restore volume' followed by a 'delete volume'. The delete failed: ANR2405E DELETE VOLUME: Volume 000591 is currently in use by clients and/or data management operations. ANS8001I Return code 14. At that time there were no processes or sessions that used that particular volume. Also we had four other volumes that displayed the same behaviour. We halted the server and restarted it again which solved the problem. The volumes were no longer 'in use'. Today we noticed two other volumes that seem to have the same problem so I'm beginning to suspect that I've found a bug in the server. All these volumes have one thing in common: When I seacrh the activity log for their mounts and dismounts I can't find a dismount message after their last mount (before they become 'unavailable'). It is as if the volumes are unmounted by the library but TSM isn't being notified of this. Anyone seen this before? Cheers, Henk.
