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. -- Jon H.
