Backup Central

Dear All,
I am running bacula 5.0.3 on Solaris 10 x86. I have a Dell TL2000
24-slots Autoloader Library with 2 HH LTO5 Drives. The changer works
and the device will load tapes and write backups. However, I'm kind of
in the dark as to how to get it to use the 2nd drive. The
documentation is real "thin" in this regard. I've setup the "Drive
Index" parameter and listed both devices in the Autochanger config. I
was reading about a "PreferMountedVolumes" but that doesn't seem to be
the solution to my issue. I'd like to know if

Job A in Pool A writing to Tape 0 can run at that same time as Job B
in Pool B writing on Tape 1

How to make Bacula use both Drives? I purchased the unit because
Bacula docs says it can use multi-drive autochangers. I also purchased
it because a single-tape drive just isn't enough to capture everything
daily to tape.

Thanks for the help,
Shon


Autochanger {
Name = TL2000_Library
Device = TL2000_DTE0, TL2000_DTE1
Changer Command = "/opt/csw/etc/bacula/mtx-changer %c %o %S %a %d"
Changer Device = /dev/scsi/changer/c3t2002000E111471E5d1
}

Device {
Name = TL2000_DTE0
Media Type = LTO-5
Archive Device = /dev/rmt/2cbn
LabelMedia = Yes
AutomaticMount = Yes
AlwaysOpen = Yes
RemovableMedia = Yes
RandomAccess = No
AutoChanger = yes
Spool Directory = /mnt/backup1/bacula/spool
Alert Command = "sh -c '/opt/csw/sbin/tapeinfo -f %c |grep TapeAlert|cat'"
Maximum Changer Wait = 900
Maximum Rewind Wait = 900
Maximum Open Wait = 900
Drive Index = 0
}

Device {
Name = TL2000_DTE1
Media Type = LTO-5
Archive Device = /dev/rmt/1cbn
LabelMedia = Yes
AutomaticMount = Yes
AlwaysOpen = Yes
RemovableMedia = Yes
RandomAccess = No
AutoChanger = yes
Spool Directory = /mnt/backup1/bacula/spool
Alert Command = "sh -c '/opt/csw/sbin/tapeinfo -f %c |grep TapeAlert|cat'"
Maximum Changer Wait = 900
Maximum Rewind Wait = 900
Maximum Open Wait = 900
Drive Index = 1
}

Yes. That should work (and does for me) without much fuss. You get
into a more difficult situation if you want both drives to use the
same pool at the same time.

Can you look at my config and see if there is any missing or incorrect
element? I was also wondering if MaxConcurrentJobs for Devices might
need to be set. Though this seems to apply to getting 2 drives running
jobs from the same pool.

I did not see anything that was obviously wrong.

I was also wondering if MaxConcurrentJobs for Devices might
need to be set. Though this seems to apply to getting 2 drives running

I do not think it needs to be set for devices however you do need to
set it in bacula-dir.conf more than 1 time to get concurrency. I think
in the director and storage resources are needed at minimum then
possibly client resources depending on your needs.
