Personally, I've used amlabel -f in that sort of situation (the -f
forces the tape to be relabeled even though is already has one and
the new label is already in use) and it's worked fine.  I would expect
amrmtape to cause amanda to forget that the tape even exists and refuse
to recognize it in the future (until relabeled).
