Hello,
we need help about reclamation in our tape pool (IBM 3494).
We run ADSM 3.1 on MVS server.
It seems that the reclamation processes do not run logically (we applied
the patch concerning aggregates):
as you can see below, adsm reclaims tape 3180 by writing on tape 3276,
which becomes full, then asks for tape 3323 (scratch tape).
Tape 3323 is almost immediately deleted!! and tape 3510 gets asked
Next reclamation process: adsm reclaims tape 3276 which was just written
to!!
This kind of loop continues then. We have recl=67%.
Does anybody experience the same situation?
IBM, is there a bug, will it be corrected in the awaited definitive
patch concerning the existing error in reclamation (logical spaces)?
Please help, our tape robot is going to be full in a few days!!
