Can anybody confirm "update slots" is working (regarding ALL drives)
correctly for them in a multidrive autochanger environment? If yes,
could you share your mtx-changer script and bacula-*.conf please?
Thanks,
Sebastian

I get it to unload drive1 as well?
As I read in the archives "update slots" is the only way to resolve
conflicts of the type "drive0 wants tape #14 but it's in drive1 at
the moment".
Please always tell us what version of Bacula you are using.
The place I'd look at is your autochanger script. Does it work
flawlessly? Perhaps the drive number is not being passed/processed
properly.
I'm using 1.38.5. The mtx-changer script work's well, I can use it
to load/unload tapes to/from both drives.
If I issue the following command:
sudo /usr/local/bacula/etc/mtx-changer /dev/scsi/changer/
c4t2100001086119230d0 loaded 1 /dev/rmt/1cbn 1
it does what it should (basically grep for "Data Transfer Element
1:Full").
Seems the update slots command that does not ask drive1 if it has a
tape in it or not. If I'm right "update slots" should empty all
drives. Now, the output of "update slots" looks like:
*update slots
Automatically selected Storage: neo4000
Enter autochanger drive[0]: 1

Bacula does not even try to find out if it must unload drive1 or
not but according to status storage it still has a tape in it:
Device status:
