When adding additional SSDs to the HPE 3PAR StoreServ 8200 with an existing RAID5 7+1 configuration, it is advisable to reconfigure the CPG (Common Provisioning Group) setsize to RAID5 5+1. This reconfiguration will allow the array to better balance the additional drives and optimize the use of available storage. After changing the setsize, running tunesys will ensure that the data is redistributed across the new set of drives, optimizing performance and availability.
