I think you will have to use a changer script like chg-manual.

That doesn't sound good. Says you have 8 tapes and earlier you
said you might use 3 per run.  Further, this says you might
run dumps 28 times between level 0 dumps.  Not good at all.

Norstead01 still has data on it that amanda believes you want to keep.
You have used Norstead01 before and have not gone through a tapecycle's
worth of tapes since using it.  See options to amadmin about manipulating
the tapelist.

What is this, another keyword I did not see sneak in?
