I should use an HP-autoloader tape-robot.
I've just installed mtx module to do it, but I have some doubts on how to proceede.

I'm using Suse11-sp1.

First of all, can you suggest me how to verify the correct behavior of the autoloader? I mean, if the driver are correctly loaded for this device.
I check it via "mtx status" but I've response "cannot open SCSI device '/dev/changer' - no such file or directory".
So I try to check /dev/st0 and /dev/sg0 , but the response in both case is "cannot open SCSI device xxxx - no media found".

The autoloader is linked to a HP-SAS switch.

Thanks in advance,
