If you are going for a quick fix, downing the drives would work just
fine. Nothing wrong with that. If you are looking for a more interactive
way to do things, you can use robtest to manually move tapes around.

Again, robtest is probably the simplest way to manually move tapes
around in the library.

These types of questions are easy only if you already know the answers
;-)
