We have had a similar problem with a ATL library for our main frame
recently which we are currently upgrading.
The best carts to remove we found were carts that were 100% full or
close to this percentage and mark these carts as unavailable.

Subject: silo slots filling up quickly

Folks,

Unfortunately our library is running out of slots very quickly and we
are
not
gaining many scratch tapes even though we are very aggressive with
reclamation.

I have been relocating tapes to an external rack giving the condition:

wherestatus=Full and days=120

However, the system has recently been asking for many of these
tapes to be inserted back into the library for reclamation.

Does anyone have any advice on which tapes that are the best to
remove from the active silo into a storage rack?

Thanks again!
