Hello,
I am working with a Tandberg Storage Loader LTO2 with 8 Tapes.
Linux 2.6.13 (Suse 10)
Bacula 1.38.5
The loader had passed all tests with btape and work fine with mtx-changer.
All Jobs are running but if Bacula should change the tape the tape would
only be unmounted and Bacula is waiting until I load a new tape manually with
mtx. If I list the pools the in changer flag is on.

Also the "update slots scan" function doesnt work.
I got the following output at the console.
Below you can see the mtx-changer script and the bacula-sd.conf.
I hope anyone have some idea.

# 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.
#
# 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.
