I believe that dsmserv display dbbackupvolume makes use of an intact
volume history file.

I would just run

        dsmserv restore db devc=tapeclass volume=SU3689L1

and see what happens. Keep in mind that if the version of TSM that wrote
the db backup is at a more recent version than the version currently
installed, you're likely to incur problems. Also keep in mind that once
you start the restore, and it fails for whatever reason, your currently
running version of TSM will probably not be usable either.
