I've been skimming through alot of forums and the bacula manual pages
without much success, I think its a config issue rather than a hardware
one.
Below are the test commands I've tried and the output. If anyone has a
working bacula L280 or DLT7000 setup I'd be curious what config is being
used in bacula-sd.conf for the Autochanger and Device.
Been playing around with my config, it was setup as below for the listed
tests:
bacula-sd.conf
---
..
..
Autochanger {
Name = L280-Library
Device = SUN-L280
Changer Device = /dev/sg1
Changer Command = "/etc/bacula/scripts/mtx-changer %c %o %S %a %d"
}
Device {
Name = SUN-L280 #
Media Type = DLT7000
Archive Device = /dev/nst0
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = yes;
Device Type = Tape
RandomAccess = yes;
AutoChanger = yes
Drive Index = 0
}
..
..

The mtx-changer script is default as per release the Debian 3.1 backport
version 1.38.11-5.

WEOF on non-appendable Volume
..

The autochanger test then continues to loop on the WEOF error.
At one stage of testing with a different config I was having the drive
timeout and error on the unload command, the following would appear on
the L280 display:
---
SET_DRV_TIMEOUT
HARDWARE ERR 94h
---
If the unload command was ctrl-c'd while waiting for completion the tape
would then eject and be returned to correct slot. Using the drive itself
load and unload works fine which leads me to believe its a software
config issue not hardware
Thats pretty much the sum of where I'm at! Any ideas would be appreciated.
