I think I am doing something wrong in configuring my autochanger. Would
someone who successfully uses a changer with more than one tape engine
please post their configs so I can examine them? The field the I am not sure
about is the "Changer Device" in the Device section.
>From the documentation I read: " The specified *name-string* must be
the *generic
SCSI* device name of the autochanger that corresponds to the normal
read/write *Archive Device* specified in the Device resource. This generic
SCSI device name should be specified if you have an autochanger or if you
have a standard tape drive and want to use the *Alert Command* (see below)."
Does this mean that in the Device section, my "Changer Device" needs to be
the generic SCSI device name of the changer itself or of the individual tape
drive?
My setup looks like this:
tape drive 0 = /dev/nst0 = /dev/sg2
tape drive 1 = /dev/nst1 = /dev/sg3
tape drive 2 = /dev/nst2 = /dev/sg5
tape drive 3 = /dev/nst3 = /dev/sg6
changer = /dev/sg4
The configuration for the changer and two of its drives is below. I am not
sure if I should change the Changer Device to /dev/sg4 for each of the
Device entries. Any ideas?
Autochanger {
Name = Dell
Device = ML6020-D0
Device = ML6020-D1
Device = ML6020-D2
Device = ML6020-D3
Changer Command = "/usr/local/bacula/etc/mtx-changer %c %o %S %a %d"
Changer Device = /dev/sg4
}
Device {
Name = ML6020-D0
Archive Device = /dev/nst0
Device Type = Tape
Media Type = LTO4
Autochanger = Yes
Changer Device = /dev/sg2
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
Drive Index = 0
Autoselect = Yes
AlwaysOpen = Yes;
RemovableMedia = Yes;
RandomAccess = No;
RequiresMount = No;
}
Device {
Name = ML6020-D1
Archive Device = /dev/nst1
Device Type = Tape
Media Type = LTO4
Autochanger = Yes
Changer Device = /dev/sg3
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
Drive Index = 1
Autoselect = Yes
AlwaysOpen = Yes;
RemovableMedia = Yes;
RandomAccess = No;
RequiresMount = No;
}
