At my shop we have problems with tape and tape drives with old micro-codes
of the device driver which marked tapes unavailable and sometime
it marked tape drive offline, problems fixed with most update microcode,
but very pain because I have to go thru software AND hardware level2
support.

It's worthwhile to check your micro-codes.
Good luck.

Your best bet would be a review of the Activity Log, which would show
TSM having problems with tapes - or drives.  It may be that a marginal
tape drive is screwing up the Export, and that will show up in the
Activity Log as well as OS logs like the AIX Error Log (errpt cmd).
Your info above indicates that your tapes seem fine, so a drive problem
could be causing the exasperating termination of the long-running
Export.
If you can identify such a drive, do a Vary Off to keep it out of the
line-up.
