What sort of Alpha?

Which Exabyte?

What kind of tape?

What else is in the system?

Posting the messages printed by the kernel on boot would be a help. Also
post the text printed out when the system is on it's way down.

Can you trigger the problem with anything other than the backup reading program
(restore?)? Like, dd?

Also check the obvious stuff (probably again) like SCSI termination, IDs, etc.

Is the Exabyte known to work on any other machines?
