Andy A couple of questions:
Nothing in the AIX errlog? Does it ONLY do it on the long running DB2 backup? Maybe it's worth running something outside of TSM so write to one of these FS's to see what happens? As for question 2, I "think" if you are writing a backup direct to a volume, and you get a write error, the job fails. I think I've had this same behavior myself.

I am running TSM 6.2.1.1 under AIX 6.1.5. I am writing data to a Data Domain DD880 using NFS. We have a long running DB2 backup that backs up about 7TB. By the way, this is a fairly new setup. Most things are fine, but sometimes I get: DATE_TIME: 2010-10-06 11:32:11.000000 MESSAGE: ANR8503E A failure occurred in writing to volume /tsmstg/cabdd01/tsmcabu/stgfile/dir2/000002CF.BFS. (SESSION: 163) DATE_TIME: 2010-10-06 11:32:11.000000 MESSAGE: ANR1411W Access mode for volume /tsmstg/cabdd01/tsmcabu/stgfile/dir2/000002CF.BFS now set to "read-only" due to write error. (SESSION: 163) DATE_TIME: 2010-10-06 11:32:12.000000 MESSAGE: ANR0523W Transaction failed for session 163 for node UPBCCLND02 (DB2/AIX64) - error on output storage device. (SESSION: 163) So far, the Data Domain people say everything is fine, and I can't find anything relevant in any logs. #1) How would you guys debug this #2) It seems to me that TSM should mount another volume if it gets a write error. Is there something I am missing to get it to do that? I hate dumping hours of backup that apparently DB2 uses 1 transaction for. Thanks for any information that you can provide. -- Andy Carlson --------------------------------------------------------------------------- Gamecube:$150,PSO:$50,Broadband Adapter: $35, Hunters License: $8.95/month, The feeling of seeing the red box with the item you want in it:Priceless.
