Hi list,

Sorry to post again so soon with a similar problem but i'm trying to setup
another autoloader as a test rig for another situation. This time its a DDS3
from HP.

I'm getting the same error as before regarding the /dev/sg* and permission
denied when i set my changerdevice in amanda.conf.

Below is an out out from the SCSI section of my messages on this box. This
time i also have a CDROM and i don't seem to be able to set the
channgerdevice. I have tried /dev/sg0 through /dev/sg7 but i just get
permision dened for them all. What should it be?

thanks

Tom
