I've seen this before (STK9740 w/Sun E450 master).  Problem was that the
media database and robotic inventory were severely out of synch.  Had to
power off the storage unit and bounce NBU daemons to get everything back in
synch.  Happened a couple times while we were training folks on vaulting
procedures.

                Subject:        [Veritas-bu] Multiple tapes cannot be
mounted

                Hello All:

                We recently started to run into a problem where a backup
will
                kickoff, and the job will try to mount all the scratch tapes
in a
                robot; tries one, then goes to the next, etc, etc.
(happening to
                both STK9710 and L700/DLT 7000 Drives). The tape does not
get
                assigned but does get moved to the pool defined by the
class. The
                All Log Entries reports that the tape is either, misplaced,
write
                protected or unmountable. The only way to resolve issue is
to
                turn the robot off and on and reinventory. When the job is
kicked
                off again, it writes to one of the tapes that was just
tagged as
                "unmountable".

                We see this in our NBU 3.2 and NBU 3.4 DataCenter
environments.

                Anybody seen this before?

                Thanks.
