Hi Richard,

Not anymore :) Used to use an SAS LTO3 based MSL2024 on a project I worked at
a while back. TBH it *just worked* and worked well too. Would recommend one to
anyone that needed an autochanger of this size. Was quick and worked. What more
do you need :)
Have attached the salient directives from my notes below, hope they're of use.
Was using a relatively old Bacula version back then (not sure which maybe 1.38
or early v2), but the important bits haven't changed much, so should be valid.
Have also added the mtx-changer I was using. Can't recall if I changed this
from the default shipped one either, but...
If the configs get munged, send me an email and I'll send you an attachment,
not sure this list server allows them.
HTH

# If you set in your Device resource
#
# 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:
# CommandFunction
# 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?
#
# 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.
