Q1.     TSM server expires offsite (copypool) copies together with primary
copies according to rules set in copygroups. You can see how utilization
decreases on offsite volumes after expiration run. Actually you are
looking for *reclamation* of offsite volumes. Very descriptive and short
(half page) explanation can be found in redbook "TSM Concepts" (SG24-4877,
*great book*), p. 88, "5.4.2 Reclamation of offsite volumes".
In short: verify the "Reclamation Threshold" in the output of 'q stg 
<offsite-pool> f=d' is below 100 (%).

Q2.     I cannot understand what exactly are you doing but suspect your
tapes are already marked on-their-way-to-offsite using 'move drmedia' and
thus TSM is not using them. Properly configured offsite rotation scheme
and offsite reclamation should be implemented. They can allow you to have
"10%" from yesterday to be written through reclamation together with
today's "10%". When those "20%" reach the vault previous tape will become
eligible to be brought back.
Chapter 9. "Tivoli Disaster Recovery Manager" of the same redbook may be
of big help on this topic.

        Subject:        File Expiration


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!!!!!!
