Hello,
You have probably used the default definition for a Device which
is setup for a tape drive. You didn't provide any information
about your setup (such as bacula-sd.conf) so I cannot correctly
answer. However, I suspect that you have:
AlwaysOpen = yes;
I would also like to know how to get tapes unmounted after a job. I have a
Virtual Tape Library (VTL) between my system and a Physical Tape Library
(PTL) and the VTL will not write to the PTL until the tape is unmounted. I
know that tapes are kept mounted for faster access time for the next job,
