They are reclaimed the same as physical volumes.  Just like physical
volumes, they need to be 100% empty before they return space and can be
reused.
The reclamation process will move the data off eligible volumes (volumes
under the reclamation threshhold) in order to make them 100% empty.

Make sure you are running reclamation on both the storage pool on the
source server as well as the storage pool on the target server.

Re: [ADSM-L] Does Move Data recover space on virtual volumes?






Joerg,
The nut of the problem, if I have this right, is that virtual volumes
aren't reclaimed the same way as physical volumes. They have to be 100%
reclaimable before they return any space. Their pct_utilization does go
down, but the empty space in them is locked until they are completely
empty.

Expiration finishes every day here, now that we are on TSM 6.2.  And, we
run reclamation assertively on all storage pools. Collocation is set to
'NO'.

With my best wishes,
Keith
