Hi Wayne,
I have an IBM 24 slot library as well which I had a similar issue on.
The cause is that the I/O station is listed differently than the rest of
the slots by the mt command. I had to tweak the mtx-changer script
slightly to recognize my I/O station as a slot.
It's because of the parsing logic in the script, the extra
'IMPORT/EXPORT' bit causes the script to ignore it. You can tweak the
script so it sees that as a slot.
I've attached my version that treats the I/O station as a slot.

Hi all,
Apologies but my google skills have failed me, hopefully I can catch
someone in a happy end of working week mood.
Just wondering if anyone has used an old IBM TS3100 with Bacula and got
it to recognise tapes that are in the IO Station?
I'm running Bacula 5.2.5 on Ubuntu 12.04. If I run an mtx status
command I get something like the following:
Storage Changer /dev/sg11:1 Drives, 24 Slots ( 1 Import/Export )
Data Transfer Element 0:Full (Storage Element 3 Loaded):VolumeTag = NPC282L2
Storage Element 1:Full :VolumeTag=NPC281L2
<snip>
Storage Element 23:Full :VolumeTag=NPC305L2
Storage Element 24 IMPORT/EXPORT:Full :VolumeTag=NPC280L2
So I can see all 24 slots + the tape in the drive (from slot 3). Bacula
seems completely blind to Storage Element 24.
If I run update slots in bconsole the 24th slot is missing:
3306 Issuing autochanger "slots" command.
Device "IBM" has 24 slots.
Connecting to Storage daemon Autochanger ...
3306 Issuing autochanger "list" command.
Catalogue record for Volume "NPC281L2" updated to reference slot 1.
<snip>
Catalogue record for Volume "NPC305L2" updated to reference slot 23.
Its not a massive problem but it has been bugging me for a while. If
anyone has any ideas it would be appreciated.

# Bacula interface to mtx autoloader

# Changer Command = "path-to-this-script/mtx-changer %c %o %S %a %d"
# you will have the following input to this script:
#
# So Bacula will always call with all the following arguments, even though
# in come cases, not all are used.
#
# mtx-changer "changer-device" "command" "slot" "archive-device" "drive-index"
# $1 $2 $3 $4 $5
#
# for example:
#
# mtx-changer /dev/sg0 load 1 /dev/nst0 0 (on a Linux system)
#
# will request to load the first cartidge into drive 0, where
# the SCSI control channel is /dev/sg0, and the read/write device
# is /dev/nst0.
#
# The commands are:
# Command Function
# unload unload a given slot
# load load a given slot
# loaded which slot is loaded?
# list list Volume names (requires barcode reader)
# slots how many slots total?
# listall list all info
# transfer
#
# Slots are numbered from 1 ...
# Drives are numbered from 0 ...
#
#
# If you need to an offline, refer to the drive as $4
# e.g. mt -f $4 offline
#
# Many changers need an offline after the unload. Also many
# changers need a sleep 60 after the mtx load.
#
# N.B. If you change the script, take care to return either
# the mtx exit code or a 0. If the script exits with a non-zero
# exit code, Bacula will assume the request failed.
