Expiring and recycling are two separate tasks.  It depends on exactly
what you're trying to accomplish, but I might let them expire and simply
prevent the recycling.  That retains most of the capabilities (saveset
restores are still easy), but avoids some of the more complex  tasks.

For instance, are you going to be doing many tape rotations into/out of
the library?  If not, I might dump the volumes currently online and run
them through a quick 'nsrmm -o manual <vol>'.  (I'd save the list so it
could be quickly undone later).  If you're moving tapes around, that
becomes more complex.

If you really need to avoid the expiration, all you need to do change
the retention on at least one saveset on the volume to the point you
want. This change must be done *before* nsrim gets around to marking the
volume expired.  There you can use 'nsrmm -e <time> -S <ssid>' to give
it a new retention date.  You can't do this after it's recyclable.
