The former. I have 3 SCSI devices, but the other two are disks with
only LUN=0. The tape drive shows up last in the list from
/proc/scsi/scsi. I suppose that's why the sg driver puts its other LUN
at /dev/sg3?
I'm just a bit curious, but I'm also worried about the number changing
and breaking Amanda if I add or remove SCSI devices from the system. I
always tell people that one of the big advantages of Unix over Windows
is that devices don't shift from D: to E: to F: as you add disks, so
scripts and software still work.
