This indicates that TSM doesn't know about the tape in the drive,
suggesting that either it didn't put it there (as in independent
action by an operator) or that it thought that an action like a
dismount actually occurred but really didn't, due to a drive problem.
Look back in your TSM Activity Log for the volume name which you found
in the drive and see what transpired then; or the last action TSM knows
it performed on that drive.  Look for device errors in your OS error
log.  You may need the drive serviced, or have its microcode updated
so that it behaves better.

In the mean time, get that tape out of the drive and return it to its
storage cell so that it can be properly used in upcoming operations.
You may need to update the volume's status in TSM to make it available
for use, as the library may have flagged it as misplaced.
