Ugh. The inability to get files back from the copy pool may indicate that
Backup Stgpool operations have not been ongoing or failed for some reason.
Given these circumstances, you may have a TSM system which is no longer viable.
I would suspend operations until you figure out what's going on: further
sessions may be writing new storage pool data which would not be usable later.
Do 'Query Volume 050399JA Format=Detailed" to get the last write date, and then
begin inspection of your Activity Log, expanding around that time, looking for
problem indications. Your operating system log may have more info. Hopefully,
this is not a shared library where TSM tapes are being overwritten by some
other application. If device drivers or drive firmware were updated recently,
review that. Turning on TapeAlert may help, going forward. At this point it's
a matter of finding out how much damage there is, and isolating a cause...
