# If you set in your Device resource

# Changer Command = "path-to-this-script/disk-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.
+# in come cases, not all are used. Note, the Volume name is not always
+# included.

-# disk-changer "changer-device" "command" "slot" "archive-device" "drive-index"
-# $1 $2 $3 $4 $5
+# disk-changer "changer-device" "command" "slot" "archive-device" "drive-index" "volume"
+# $1 $2 $3 $4 $5 $6
#
# By default the autochanger has 10 Volumes and 1 Drive.
#
# any other part of the directory name. These restrictions could be
# easily removed by any clever script jockey.
#
-# Full example: disk-changer /var/bacula/conf load 1 /var/bacula/drive0 0
+# Full example: disk-changer /var/bacula/conf load 1 /var/bacula/drive0 0 TestVol001
#
# The Volumes will be created with names slot1, slot2, slot3, ... maxslot in the
# base directory. In the above example the base directory is /var/bacula.
# /var/bacula/slot3, ...) this script will create a /var/bacula/loadedn
# file to keep track of what Slot is loaded. You should not change this file.
#
+# Modified 8 June 2010 to accept Volume names from the calling program as arg 6.
+# In this case, rather than storing the data in slotn, it is stored in the
+# Volume name. Note: for this to work, Volume names may not include spaces.
