I run Reclamation of 70% during the weekdays and 51% during the weekends.
Between this and collocation in the primary pools, I have 417 scratches out
of 2,480 total onsite and offsite tapes.  That's also with an average of 7
days retention, and 3 day reuse period.

Howdy Folks,

Anyone noticed you can't do decimals...  Like 96.5 or 99.9 .  I know <1% is
not going to make a difference, but hey I have found where they do and can
come in handy sometimes...  I think this would make a nice to have feature.

I think the IDEAL pct for reclamation really depends on ur system
environment(performance and tape drive usage) and personal taste.
I think  65% is very respectable #, but the way I understand reclamation is
that anything  51% is technically okay.  I don't think there would be any
folks out there using this #... maybe..

Here's one

select count(*) from volumes where pct_reclaim>95 and
stgpool_name='TAPE_DR_COPY'

James,

Do a "query  volume" and look at the  "pct util" column for the tapes
offsite.   Compare that value with the Reclamation Threshold for your
pool.   If there are a lot of tapes that meet that threshold and they
don't come back when they should then you should look to make sure the
reclamation is running when it should and if it is running to
completion.Reclamation Threshold
