Thanks to all....I had a brain block...I was thinking our copy storage
pool was collocated, as are our primary pools,,,,,,boy, it's hard to get
back in the saddle (and stay on),,,,  :-)

DEFINITION OF BACKUP
RULES:
VEREXISTS: # of versions to keep while file exists (adjusted by
RETEXTRA)
VERDELETED: # of versions to keep on TSM when file is deleted from
client
RETEXTRA: # of DAYS to keep non current versions defined by
VEREXISTS
RETONLY: # of DAYS to keep file(s) on TSM after deleted on client
(adjusted by
VEREDELETED)

I would think you would set VEREDELETED to 1
After all , you are deleteing all the 'extra' versions after 7 days.

Yes, we reclaim copy pools. Threshhold set to 50%
setting it at 80% requires a lot of consolidation of a lot of volumes
that have only 20% empty. No wonder you have long runs that need to be
manually terminated.

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
