Quick answer: Because that tape is then in the drive, and thus the first
choice to use for Bacula.

Have you tried the 'relabel' command? That won't change the tape
preference, but it will keep your catalog intact.

In the end, tape 3 is loaded, right?

By unloading this tape, I suppose... simply 'umount' followed by a
'mount slot=0' which will tell Bacula it can operate the autochanger
again, but this does not load a tape.

It is possible by giving the proper slot to to the mount command. On the
other hand, it's not normally necessary, as Bacula simply uses whatever
tape it finds, if that's suitable.
