All,
Here is the output of mtx status command and mtx-changer run from
command line for comparison. I am running Bacula 2.2.7 on Solaris 10_x86.
Also, I still do have to run mtx status command 2x from command line for the
additional slot to be seen before updating slots in bconsole. I think this
is an Exabyte issue, but is low on my fix list right now. Also notice that
the IE slot is still numbered 24, even though its in the RH magazine, not
LH.
This is the most significant change in the mtx-changer, but I can't recall
if there were others

# 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:
#
# 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)
#
# 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.
