We keep our reclamation threshold at 100% and schedule reclamation to run
at off-peak times by reseting the reclamation threshold to 60%. A setting
of 60 will move all the data off of volumes with %util of 40 or less,a
setting of 90 will reclaim volumes of 10% util or less..etc. We also will
do small reclamations during the day by doing a Q VOL and finding volumes
with a low (1-10%) utilization and changing the Reclamtion threshold..UPD
STG STORAGEPOOL RECL=## to reclaim just those volumes,both onsite and
offsite.

Subject: ADSM OFFSITE media data
I have ADSM V3.1.01 set up to run a copy of my main tape storage
pool to a Copy storage pool on a daily basis. This is then set as
ACCESS=OFFSITE and taken to our remote safe.
When I run Q VOL against these offsite tapes, I notice that some
tapes are 0.8% utilised.
My understanding of the way ADSM manages these tapes is that at
some point it should recopy the data on these tapes and set the
tapes as Empty and ready to return.
Is there some parameter which decides at what point these files are
copied and the tapes Freed ?
Is it based on percentage of tape used or on the number of files on
the tapes ?
NB. I am not using DRM and would like to avoid it if at all possible
!
