It might be related to size of reclamation stgpool and transaction size.
If reclamation have filled the reclamation pool to 75% and next set of
files in inter-server transaction is worth 20% of reclamation pool size,
you will have the pool filled to 75+20=95% before migration threshold is
passed.

Subject: Re: Tape reclaim & stgpool migration question/
Reclamation % is set to 50 on tapepool.Reclamation Threshold: 50
Migration set as High Mig Pct: 80 on SQUEnTIal ACCESS Stgpool disk with
devclass cfile.
Low Mig Pct: 0
Migration takes place but after certain retries . What I see is after dsik
stgpool reach 95% it retries with No more space in stgpool of disk pool to
which tapes are getting reclaimed.
My question is why it is not sensing 80% on sequential access disk
stgpool.
Thanks

You may have a little confusion about Reclamation and Migration.
Do 'q stg xxxpool f=d' and find 'Reclamation Threshold' which governs how
reclamation will be done.
Highmig=xx and lowmig=xx are parameters that works only for Migration of
data from one pool to another. When a stg reaches highmig #, it kicks
migration until reaches lowmig#.
Hope this helps.

All-
I recently created reclaim stgpool with upper mig to 80% and lower mig to
0%.
But the CFILE devclass stgpool that is disk when gets to 80 % migrate
level
, tapes do not stop to reclaim but it continues .What might have been
missing????
Thanks in advance
