I misspoke. I was thinking of a situation where one tape of a
mirrored pair might be "archived". I guess the command in that
case is something like "amadmin no-reuse" (syntax unchecked).
IIRC that preserves the index; at least for non-rait situations.
In such a case, when the "still in use" tape gets recycled in
the tapelist and overwritten, would the index still be retained
for the "no-reuse" copy of the tape?
I'm still curious about handling of the indicies for multiple
copy situations and even for strip'ed arrangements. Suppose
one tape of a rait strip gets overwritten.
