Common provisioning groups

Common provisioning groups (CPGs) are user-defined pools of storage space. When a common provisioning group is created, its properties, such as RAID type and physical drive device type, are specified. HPE Storage operating systems automatically create the underlying logical drives for the common provisioning group that have those properties.

Compaction

Unused space in a common provisioning group can be reclaimed by compacting it. Compacting using the Trim option performs a trim that reclaims space in empty logical drives. Compacting using the Full option performs an initial trim, and if possible, reclaims more space by moving data and performing a final trim.
