Yes, that could be a problem.

Does the drive have a tape loaded at this point?  The error suggests it
doesn't.

With a single drive, I wouldn't expect to do mount until the tape is in the
drive.  It could be more complicated with an autochanger...unless Bacula
should be loading a tape automatically (though possibly it would be the wrong
tape).
