Martin,

John Drescher e-mailed that the unmount command (which we had been using
after each job) causes the drive to enter into a blocked state such that
manual intervention is required afterward to load the drive again.  John
suggested using the release command instead and I have found that doing so
does not block the drive and thus should solve our problem.

Does Bacula issue any mtx-changer commands (to try to load the tape)?

Do they do anything or do they fail?

The log might show that.
