On your Autoloader problem:
Make sure your SCSI ID's are correct. They're usually 5 for the loader, and 6 for the drive. You can change the numbers on the front panel (I have a 122T, it's similar). Make sure that the SCSI cable is disconnected from the server when you do this.
Turn the autoloader off, re-connect the loader to the server, and turn the loader on first. Make sure it's completely up and running, then turn your server on. It should see the autoloader as Dell 1and the drive under it as Dell 2, with the slots of the loader under Dell 2.
