Re: 3par reclaim stroage space after deletion of VV
If you know the VV created from which CPG then you can check at the CPG level.
showvv -cpgalloc <VV_name> // This command will help you to understand VV created from which CPG
showspace -cpg <CPG_name> // This command will show space under "Free" Column. Note the size of "LDFree" column.
compactcpg -dr <CPG_name> // This command will help you to understand if you compact the CPG then how much approx going to reclaim.
compactcpg -f <CPG_name> // This command will actually compact the CPG. Note if space reclaim in TB then better to plan in out of office hours or in weekends. Sometimes this may create performance issue or if any other tune operation action then it will clash with that.
Again run showspace -cpg <CPG_name> // here you should see space getting reduce from "Free" column and will added back to "LDFree" Column.
If you want to monitor space from raw space level then better to check -> showpd -c -p -devtype <drive_type>
If you are using AO (Adaptive Optimization) then space monitoring will be complex. You need to first understand VV space distributed among whatall CPGs. run below command to get that details first,
showvvcpg <VV_name>
Hope this helps!

showeventlog -debug -oneline -msg reclaim -min 1440
