A couple of weeks ago I was given the opportunity to take on the TSM admin
role :-)

I was wondering if anyone reclaims copy storage pools. Currently, we
execute a schedule to reclaim space from our copy storage pool using the upd 
stgp copypool recl=80 command, this is scheduled for 15:00. Then we have a 
schedule to set the
threshold back to 100%, using the upd stgp copypool recl=100 command at 18:00, 
but that doesn't work. We usually cancel it manually
after 23:00.  I took TSM classes about 4 years ago, and my book recommends
leaving the threshold 100%, meaning no reclamation will occur. Once all
offsite volumes go into an empty status we can bring them back.

Our versions info - versions data exists, versions data deleted, retain
extra versions, and retain only version are all set to 7. Wouldn't the
tape empty after 7 days?

Thanks,
Debbie
