Answer 1:
Expiration (and reclamation) should happen normally based on your Reclamation 
threshold. We have two offsite copypools and we have them set for 70 and 80% 
(respectively). It seems to work well. It's not the % utilized however that 
triggers reclamation, it's the % of reclaimable space (slight difference). You 
can check this by looking at the individual volumes, or by writing a query.

Answer 2:
It sounds like you have collocation turned on. Turn that off and your tape 
consumption should go way down.

Question.
How does TSM handle the expiration of files on media stored in our offsite
storage facility??
Does it wait until all the data has expired to recall the tape back. Help!!
I have a ton of tape offsite that has less than 10% of the tape utilized.

Question 2.
When I go to DRM Offsite recovery media mountable for tapes to go offsite I
check the media with "q vol xxxxxx f=d" and the media is less than 10%
utilized so I leave them in the library to be used on the next migration but
these tape will no longer mounted to be utilized for the remainder of the
media. Is there a way to have TSM continue to mount these tapes until they
are totally utilized. Help I am going thru a ton of tapes!!!!!!
