I still don't get it why there is no free space showing in the cpg?when I delete data on VV, shouldn't free space be shown in cpg?
Eventually it will, but it isn't instant. What you see under Usr Used is what the 3PAR knows to be the total of all 16kB blocks in the VV which isn't all zeros. That is where the Usr Rsvd should end up when all the space is reclaimed. If you delete a VV it will be rather instant, but when deleting content within a VV there is a lot of background tasks/defragmentation (not sure on the details here) that is needed to free that space.
Just to feed my curiosity. How much space is reclaimed per 24 hours? And how many physical drives (and of what type) do you got in the system? I've seen large 7400-4n do 1+TB a day, but also seen very small 7200s doing low double-digit GB per day.
