Hoping it is just the "machine is not plugged in" simple, let me ask this.

You say "amanda is setup ...".  By that I assume you mean the software.

But what about the real user amanda.  If you login as amanda and run
the "id" command, are you in group operator?

Logged in as user "amanda":

> id
uid=1009(amanda) gid=5(operator) groups=5(operator)

If so, to rule out device permissions further, does amlabel work when
either of the following is true:

1. /dev/ch0 is set to permissions 666.
2. amlabel is group operator and setgid (permissions 2755).

I ran amlabel before and after both 1 and 2 above.  All return the same thing:

> amlabel bu1 BU100 slot 0
amlabel: could not load slot "0": open: /dev/ch0: Permission denied
