I would suggest looking at and testing the mtx-changer command, since it
parses the output of the MTX command. I have found that for my auto
changer i had to tweek the script since my output was slightly different
than what was expected.

New Bacula user here- I've gone over the config documentation a number
of times and I hope I'm missing something small...but I'm having issues
with 2-Sun L25s linked together with a Quantum StackLink on Debian etch
(2.6.x) with MySQL 5.0.30.
I've had the same issues with both the prepackaged Debian packages and
building from source, which suggests a config file problem...
I can load/unload tapes just fine and do all mtx commands with no
problems. All bacula services start fine (running as root). All
devices exist under /dev and permissions are correct for root. Each L25
has 2 drives available, giving me 4 drives able to write
simultaneously. However, bconsole won't run 'update slots scan' for the
autochanger (since it tries to access the drive's archive device instead
of the changer device), and I can successfully run 'btape test' and
'btape fill', but autochanger does NOTHING- just gives me another * prompt.
