3PAR InForm OS CLI Administrator’s Manual InForm OS Version 2.2.4
7.11.4 Removing a Thinly Provisioned Virtual Volume
X To remove a TPVV, issue the removevv <VV_name> command, where <VV_name> is the
name of the TPVV being removed. The logical disks belonging to the CPG from which the
TPVV draws remain.
For a complete list of arguments that can be used with the
removevv command, see the
InForm OS Command Line Interface Reference.
7.12 Commonly Provisioned Virtual Volumes
Commonly Provisioned Virtual Volumes (CPVVs) draw snapshot administration space and
snapshot data space from the logical disks in a Common Provisioning Group (CPG). A CPVV is
no different from a standard base volume until it is used to create snapshots, which requires a
3PAR Virtual Copy license. For detailed information about CPVVs, see the 3PAR InForm
Concepts Guide.
Creating a CPVV is nearly identical to creating virtual volumes as described in 7.3 Creating
Logical Disks and Virtual Volumes on page 7.3. You can use either the
createaldvv or
createvv commands to create CPVVs with static user space or CPVVs with fully provisioned
user space, respectively.
7.12.1 Creating CPVVs with Static User Space
X To create a CPVV with static user space, issue the createaldvv -t <RAID_type>
-ssz <size> -cpg <CPG_name> <VV_name> <size>
command, where:
 -t <RAID_type> is the RAID type for the created volume, specified as r0 (RAID 0), r1
(RAID 1), or
r5 (RAID 5).
 -ssz <size> is the set size in the number of chunklets to evenly spread the RAID sets
across the drive cages.
 -cpg <CPG_name> is the name of the CPG from which the created volume will draw its
snapshot administration and data space.
 <VV_name> is the name of the virtual volume being created.
 <size> is the size of the user volume in MB, specified as an integer from 1 to 2096128
(you can also specify the size in gigabytes by following the integer with g or G)
