If you are seeing write errors but no write issues showing up on the DD, start looking at the network link between the TSM server and the DD appliance.

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.
