7.8 Creating Virtual Volumes
After you create CPGs, you can create fully-provisioned virtual volumes and Thinly-Provisioned
Virtual Volumes (TPVVs) that draw space form 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 a 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 volume’s at one time. Expiration dates can be set for
virtual volume’s to save space.
For information about planning for the growth of virtual volumes, see the 3PAR InForm OS
Concepts Guide. For information about creating CPGs, see 7.2 Common Provisioning Groups on
page 7.4.
