Most of the storage administrators who manage 3PAR storage will be facing tough situations when they deal with adaptive optimization (AO) configuration, especially when you want to see the CPG wise information and growth factors.
In this article, we will try explore the CLI options and commands for collecting the CPG information associated with 3PAR StoreServ virtual volumes(vv). The commands which we are concentrating here are showvv and showvvcpg.
If you want to collect the user CPG and copy CPG information of a particular volume, use showvv command along with -cpgalloc option.
-cpgalloc option shows CPGs associated with each VV.
If you want to collect the CPG space distribution of a virtual volume after completing an adaptive optimization (AO), use showvvcpg
Eg:
The volume, esxvol1 is not part of any AO setup, hence it shows only the usr CPG and snp CPG.
Let see an example of a virtual volume(ESX_Datastore_labsvr) which takes part in adaptive optimization (AO) move.
In this, the command output shows the distribution of volume space after completing an an adaptive optimization (AO) move.
Hope this is useful. Please share your views.
In this article, we will try explore the CLI options and commands for collecting the CPG information associated with 3PAR StoreServ virtual volumes(vv). The commands which we are concentrating here are showvv and showvvcpg.
While showvv command displays the information about virtual volumes (VVs) in the system, showvvcpg command displays the Virtual Volume(VV) space distribution among CPGs in a 3PAR StoreServ storage system.
If you want to collect the user CPG and copy CPG information of a particular volume, use showvv command along with -cpgalloc option.
Eg:
mylab3par cli% showvv -cpgalloc esxvol1
Id Name Prov Type UsrCPG SnpCPG
50 esxvol1 tpvv base CPGP1_DB_FCR5_7 CPGP1_SNAP_FCR5_7
---------------------------------------------------------
-cpgalloc option shows CPGs associated with each VV.
If you want to collect the CPG space distribution of a virtual volume after completing an adaptive optimization (AO), use showvvcpg
Eg:
mylab3par cli% showvvcpg esxvol1
-----(MB)----- -New (MB)--
Name CPG Adm Snp Usr Adm Snp Usr
esxvol1 CPGP1_DB_FCR5_7 512 0 63232 0 0 0
esxvol1 CPGP1_SNAP_FCR5_7 0 1024 0 0 0 0
-------------------------------------------------------

In this, the command output shows the distribution of volume space after completing an an adaptive optimization (AO) move.
