3PAR InForm CLI Administrator’s Manual InForm OS Version 2.3.1
7.8.1 Creating Fully-Provisioned Virtual Volumes
A fully-provisioned virtual volume has a set amount of user space that is allocated for user
data. The virtual volume’s snapshot space is allocated on demand.
 To create a group of fully-provisioned virtual volumes, issue the createvv -cnt
<number> -snp_cpg <CPG_name> <user_CPG> <VV_name> <VV_size
g|G|t|T>
command, where:
◆ <number> is the number of virtual volumes to create with the designated properties.
◆ <CPG_name> is the name of the CPG from which the created volume will draw its
snapshot space and administration space.
◆ <user_CPG> is the name of the CPG from which the created virtual volume will draw
its user space.
◆ <VV_name> is the name of the virtual volume being created.
◆ <VV_size g|G|t|T> is the size of the volume in MB, GB, or TB. If g|G|t|T is not
specified,
VV_size is the number of MBs. For example, 50g specifies 50 GBs.
For a complete list of options available for the createvv command, see the InForm OS
Command Line Interface Reference and InForm CLI Help.
NOTE: Creating virtual copies or snapshots requires the 3PAR Virtual Copy license.
Creating Thinly-Provisioned Virtual Volumes (TPVVs) requires the 3PAR Thin
Provisioning license. Contact your 3PAR sales representative for more
information.
NOTE: If the - tpvv option is not specified, the created volume is a fully-
provisioned virtual volume.
