1. Ensure expiration is happening - if expiration interval in 'q stat'
output is 0 there must be admin schedule for 'expi inv'.
2. 'q stg <pool with those tapes> f=d' will show you the reclamation
threshold. It usually has to be 60-70 (%). If is 100% reclamation will
never start.
3. compare the percentage in 'q vol' against the threshold from p.2 and if
necessary lower the threshold with 'upd stg <the pool> recl=<something
less>'
And do not search yourself, there are computers for that (and search
functionality in help). Just find time to read redbook SG24-4877.

Subject:        TSM 4.2, Private won't go into scratch

Hi everyone. I have a concern.
Maybe I should RTFM, but don't have enough time to search.
I have a following concern:

Magstar 3575-L12 and 40 tapes currently in slots. I backup everyday
54GB, which occupies 5 - 7 tapes. I set in backup mgmt class number of
copies to keep 2 whenever they have been deleted or not. (retain extra
and only version are set to 2 as well). I've set backup retention to 7
days.

The collocation is 'yes'
The problem is, that the tapes won't go into scratch, it looks like the
reclamation process won't start.
What should I check?
Thanks in advance...
