Can you send the same Q STG, but with the option F=D?
Code: 
q stg VTL02_W3_3Y f=d

Also use the code tag when pasting outputs. You can obtain it by pressing the # on the button bar. That will help keep the output formatting and make it easier to read.

I was looking to see if migrated files were cached, but that's only for random pool, yours is sequential. I can't explain why there is still 21.3 pct utilized, but nothing is migrated because there is 0 pct migratable.

Unless you have to run reclamation to clear the remaining space occupied by expired objects.

i can't reclaim this pool
Code: 
tsm: CWNTSM02>RECLaim STGpool VTL02_W3_3Y wait=yes
ANR2111W RECLAIM STGPOOL: There is no data to process for VTL02_W3_3Y.
ANS8001I Return code 11.
if can't be migrated to tape. can you suggest me the way to move data to tape(ACSLS).
 
What reclamation threshold did you use?

If you check the volumes in this pool that are not empty, how much data do they hold and what is their percent reclaimable?
select volume_name,pct_utilized,pct_reclaim from volumes where pct_utilized<>0 and stgpool_name='BACKUPPOOL'

Possibly, you might need to use a higher reclamation threshold.

Alternatively, you can just do a MOVE DATA to empty the pool manually.
