Are you using a Library Manager?
If so, you need to remove the volume history for that volume by typing this command on the library manager instance: del volhistory todate=today T00015 force=yes That should get rid of all associated volume history transactions.

Rout Sent: Tuesday, September 15, 2009 11:34 AM To: ADSM-L@VM.MARIST.EDU Subject: [ADSM-L] rarely, tapes become logically unusable? Hi, there. I have a small collection of tapes which appear to have become uncorrectably unusable. They were part of a server which has been decomissioned; now tsm: CTRL>UPDATE LIBVOLUME 3592LIB T00015 status=private owner=GLMAIL ANR9787E The owner name specified is not defined to this server. ANS8001I Return code 11. tsm: CTRL>UPDATE LIBVOLUME 3592LIB T00015 status=private owner=blargh ANR8969E The owner of volume T00015 can not be updated to owner BLARGH. ANS8001I Return code 27. So, somewhere in its black little heart, TSM remembers what server that tape went with, depite the fact that the server has been off since 2005. On the one hand this is good: it prevents me from accidentally overwriting tapes. On the other hand, it's now preventing me from deliberately overwriting tapes. What do I do? Ideally, I'd like to express to the server something like 'No really, call that blank again, I'd like to reuse it'. Relabel it, force=yes, checkin=scratch? Any ideas? - Allen S. Rout
