Hi Team,

Is there any step which can be used to monitor the reclaim stroage space after deletion of VV?

 

Regards,

Sri

@SEENIVASANP 

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 execute 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. Execute below command to get that details first,

showvvcpg <VV_name>

 

Hope this helps!

And an additional command to see what's going on:

showeventlog -debug -oneline -msg reclaim -min 1440


======================
That was not planned in this way.
