Hello!

I'm trying to use a Dell PowerVault 124T Autochanger under Ubuntu Lucid, Kernel 
2.6.32-24. The Operating System is running in a virtual machine (ESX) and the 
autoloader is attached via SAS. Bacula version is 5.0.1 (24.Feb 2010 for ubuntu 
10.4).
The mtx (linux native) does not seem to work nor does the mtx-changer script 
(obviously). So can someone please help me? That would be great - and my 
stomach ulcer will vanish ;)

Here some output.

2. mtx status 

"cannot open SCSI device '/dev/changer' - No such file or directory"

So I did a "ln -s /dev/sg3 /dev/changer" and now it says

2a) mtx status

3. bacula-sd.conf

(...)

Autochanger {
Name = Autochanger
Device = Drive-1
#  Device = Drive-2
Changer Command = "/etc/bacula/scripts/mtx-changer %c %o %S %a %d"
Changer Device = /dev/sg3
}

Device {
Name = Drive-1
Drive Index = 0
Media Type = LTO-4
Archive Device = /dev/st0
AutomaticMount = yes;               # when device opened, read it
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes
LabelMedia = yes
}

(...)

I also used /dev/nst0, but I don't think that's the problem.
