Peter - See entry "Unavailable" in ADSM QuickFacts for conventional information on that status of your problem tape. Best practice in a shop is to have a periodic (nightly) job query for unusual volume states that may not be caught in a TSM activity monitor. You can go back into the server Activity Log and see how the volume got that way. Often, it's a volume that was victim to a library or drive malfunction, and may need manual action to return it to service. Or, you may have to recover a volume, a procedure which is generally discussed in the Admin Guide manual. QuickFacts also has a "Bad tape, how to handle" topic that may help. It's largely a matter of finding out how a volume got to its current state, and then dealing with it accordingly.
