Hello,
I am running into a problem with bacula wanting a mounted tape on one
drive on another drive. I have a Qualstar RLS8236 Autochanger running on
a Sun V240 with Solaris 9.
Here is an example of the e-mail I get (and messages from bconsole)
05-Apr 16:18 solweb-sd: Please mount Volume "Daily02-0005" on Storage
Device "LTO-0" (/dev/rmt/0cbn) for Job BackupCatalog.2007-04-05_04.50.00
Here is the status storage:

The tape from slot 29 is Daily02-0005, the tape from slot 30 is
Daily01-0005. But I am not sure why the SD does not identify the tape in
LTO-1 as Daily02-0005.
Here the device configuration for the SD:
# An autochanger device with two drives
#
Autochanger {
Name = Autochanger-0
Device = LTO-0
Device = LTO-1
Changer Command = "/usr/local/bacula/etc/mtx-changer %c %o %S %a %d"
Changer Device = /dev/scsi/changer/c2t0d0
}
Device {
Name = LTO-0
Drive Index = 0
Media Type = LTO-2
Archive Device = /dev/rmt/0cbn
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes
Autoselect = yes # Default is yes but not using
the both drives
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
Spool Directory = /local0/BACKUP
Maximum Spool Size=16777216000
Maximum Job Spool Size=10485760000
Maximum Network Buffer Size = 65536
}
Device {
Name = LTO-1
Drive Index = 1
Media Type = LTO-2
Archive Device = /dev/rmt/1cbn
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes
Autoselect = yes # Default is yes but not using
the both drives
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
Spool Directory = /local3/BACKUP
Maximum Spool Size=29360128000
Maximum Job Spool Size=19922944000
Maximum Network Buffer Size = 65536
}
I run two pools for incremental backups, because I was using earlier
versions of bacula that didn't support multiple device autochangers
well, When I moved to 2.0.x moved the above autochanger configuration.
In the older versions I used each drive in the autochanger independently
working the schedule so that the two drives weren't accessing the
changer device at the same time.
Any advice on how to configure the Autochanger, tape devices and even
the pools would be appreciated.
Thank you,
Tom.
