Hi,

I have just transferred my kit over to the production env. All was working
fine on dev.

This is on a RedHat machine with a 2.4.18 kernel and amanda 2.4.4

dmesg says

and /dev/sg* says

$ ls -l /dev/sg*

crwxrwxr-x    1 root     disk      21,   7 May  5  1998 /dev/sgh

but

$ mtx -f /dev/sg4 status
cannot open SCSI device '/dev/sg4' - No such device

?

the amanda user is in the disk group?

any thoughts
