let me know if you get it working i would like to see how. i have been working on mine for sometime trying to get it working. i hope i was of any help

First... I'm a little embarrassed to say, that I hadn't run lsscsi -g, but after installing it and running it I noticed that my new LTO4 drive had taken over the /dev/nst1 slot and the second LTO3 drive was at /dev/nst2. However, in doing this poking around I noticed that mtx -f /dev/sg1 status listed only 2 Drives, not the three that I had. So, without making changes to my bacula-sd.conf from above other than to update the devices for my LTO4 drive and second LTO3 drive, I did a firmware update on the tape library and the drive itself... rebooted the server and mtx then showed the three drives that I had. Not sure why it required a firmware update on the library, as it was already telling me it had three drives... After mtx saw all three drives however, I was able to successfully label all the new LTO4 tapes in the library and make them part of the proper pool... and my first backup went fine.

Hi,

I've been looking around for a while... and I haven't found anything to
answer a question..
I'm running bacula-3.0.1 x86_64.
I have an HP MSL8096, which has two LTO3 drives in in and we just got a new
LTO4 drive.

I'm getting an error when trying to use the new LTO4 drive with the LTO4
tapes... (trying to run label barcodes)
Sending label command for Volume "GFZ452L4" Slot 46 ...
3301 Issuing autochanger "loaded? drive 2" command.
3302 Autochanger "loaded? drive 2", result: nothing loaded.
3304 Issuing autochanger "load slot 46, drive 2" command.
3992 Bad autochanger "load slot 46, drive 2": ERR=Child died from signal 15:
Termination.
Results=Program killed by Bacula (timeout)

Currently my bacula-sd.conf looks like:

Autochanger {
Name = Autochanger
Device = lto3-1
Device = lto3-2
Device = lto4-3
Changer Command = "/usr/lib64/bacula/mtx-changer %c %o %S %a %d"
Changer Device = /dev/sg1
}

Device {
Name = lto3-1 #
Drive Index = 0
Media Type = LTO3
Archive Device = /dev/nst0
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes
}

Device {
Name = lto3-2 #
Drive Index = 1
Media Type = LTO3
Archive Device = /dev/nst1
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes
}

Device {
Name = lto4-3
Drive Index = 2
Media Type = LTO4
Archive Device = /dev/nst2
AutomaticMount = yes;
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes
}

And my Storage definitions from the bacula-dir.conf:
# Definition of file storage device
Storage {
Name = MSL-LTO3
Address = <host>
SDPort = 9103
Password = "Cv70F6pf1t6pBopT4vQOnigDrR0v3LT3Cgkiyj"
Device = "Autochanger"
Media Type = LTO3
Autochanger = yes
Maximum Concurrent Jobs = 20
}

Storage {
Name = MSL-LTO4
Address = <host>
SDPort = 9103
Password = "Cv70F6pf1t6pBopT4vQOnigDrR0v3LT3Cgkiyj"
Device = "Autochanger"
Media Type = LTO4
Autochanger = yes
Maximum Concurrent Jobs = 20
}

Is this the proper way to handle two different tape types? or is my error
caused by my config or just an issue with the drive?

Thanks for any information,
Mitch Anderson
