Creating Virtual Volumes
After you create CPGs, you can create fully-provisioned virtual volumes and Thinly-Provisioned
Virtual Volumes (TPVVs) that draw space from the CPGs. For greater administrative flexibility, you
can provision the virtual volume’s user space and snapshot space from the same or different CPGs.
If the virtual volume’s user space and snapshot space are on different CPGs, the user space remains
available to the host if the CPG containing the snapshot space becomes full. You can create many
identical virtual volumes at one time. Expiration dates can be set for virtual volumes to save space.
For information about planning for the growth of virtual volumes, see the HP 3PAR InForm OS
Concepts Guide. For information about creating CPGs, see “Common Provisioning Groups”
(page 81).
NOTE: Creating virtual copies or snapshots requires the HP 3PAR Virtual Copy Software license.
Creating Thinly-Provisioned Virtual Volumes (TPVVs) requires the HP 3PAR Thin Provisioning Software
license. Contact your HP sales representative for more information.
