Hello,
please, could anybody test newer version of rc-chio-changer for FreeBSD
(and possibly for OpenBSD/NetBSD) in bacula and send me, with which
configuration? It has added listall and transfer commands plus some other
smaller modifications. Personally, I do use 120 slot library with
2 tape drives.
Thank you.

#
# If you set in your Device resource
# Changer Command = "path-to-this-script/chio-changer %c %o %S %a %d"
# you will have the following input to this script:
# chio-changer "changer-device" "command" "slot" "tape-device" "drive-index"
# $1 $2 $3 $4 $5
# for example (on a FreeBSD system):
# chio-changer /dev/ch0 load 1 /dev/nsa0 0
#
# If you change the script, take care to return either the chio exit
# code or a 0. If the script exits with a non-zero exit code, Bacula
# will assume the request failed.

# Uncomment the following line, if you want to log debug output.

# Uncomment the following line, if you need to eject a tape before moving

# Uncomment one or more of the following lines, if you need to wait for

Usage: ${PROGNAME} <changer-device> <cmd> [slot] [tape-device] [drive-index]
Commands (<cmd>):
unload Unload a tape into the slot from where it was loaded
load <slot> Load a tape from the slot <slot> (1-based)
transfer <slot> <slotdst> Transfer a tape from the slot <slot> to
the slot <slotdst> (1-based)
list List full storage slots
listall List all storage slots and drives with source information
loaded Give slot from where the tape was loaded (0 = empty drive)
slots Give number of available slots
Example:
${PROGNAME} /dev/ch0 load 1 Load a tape from the slot 1
