Odd configuration error

Hi,

My amanda server for my DMZ ate its HDD today so i've been busy rebuilding
it - It has a HP autoloader and a single AIT-2 drive in it to run 2
different a,anda configs.

The single drive seems fine - I'm having issues with the changer.

when i run an amcheck on this config i get..

amcheck-server: could not get changer info: no slots available

and so i look in my config and i have my changer as sg2

i do

$ mtx -f /dev/sg2 status
cannot open SCSI device '/dev/sg2' - No such device

and

$ ls -l /dev/sg*
