Difference between how the same volume is viewed in 3PAR v Vmware

[Beer Grill]

Hi guys

I need to understand why there is such a difference in the view of capacity in the below table from the two points of view.  I need to be able to explain to my client what is happening here.

Thanks in advance

Volume is Thin Provisioned

Compaction on the CPG is done on a daily basis .

A vSphere UNMAP was carried out on the Datastore very recently.

Hello @Beer Grill,

Can you please provide more details to explain this?
I would like to take a look at the below command outputs:

showcpg -sdg
showpd -c
showspace -cpg *

Hello @Beer Grill,

Thanks for the output. But I haven't received the below command outputs as they should have been. Here the * is * only, please don't replace with the CPG name.

Hello @Beer Grill,

What I could derive from the log outputs and numbers on the table of your original post are not matching. May I know how did you arrive at those numbers?
