I'm not very familiar with the chg-manual script, but as a wild guess
you might have the wrong console device specified for your OS.

Looks like this is your main problem, you don't have permissions to
the tape drive.  Odd, since you say you are running amrecover as
root.  Is the tape actually loaded in the drive?  Can you (from the
command line) run 'mt -f /dev/nsa0 rewind' successfully?
