I would be better to mark the tape unavailable.  If you mark it read-only then 
TSM will still try to mount it for restores or reclamation.  At times we have 
need to checkout primary tapes.  When we do this we update vol acc=unav.

By the way Mark, we ARE doing backupsets of that node along with a regular
backup also, I know, I know......

Thanks :)

You could do that. You could also run a regular nightly backup (no
collocation) of the node, and then run a weekly backupset of the node.
That gives you a collocated weekly "snapshot" of the entire client.
There is no tape volume access flipping to be remembered, and you don't
have to have a special storage pool for just those 2 or 3 clients.
Backupsets' expiration periods are easy to set, so you can get rid of
those you don't need anymore.
