this is kind of what I am fighting. ... but to automate reclaiming tapepool
tapes, we have an administrative schedule that issues

        set stg tapepool rec=5

and another command to later do

        set stg tapepool rec=100

to stop it.  We do this for both the tapepool and copypool.  Right now my
problem is the copypool takes a long time and is very slow.

You can issue these by hand to get reclamation started.
