7.10
Removing Virtual Volumes
3PAR InForm OS CLI Administrator’s Manual InForm OS Version 2.2.4
 <N:S:P> is the location of the target port used to export the virtual volume.
 <host_name> is the name of the host to which the virtual volume was exported.
For information on arguments which can optionally be specified with the
removevlun
command, refer to the InForm OS Command Line Interface Reference.
7.9 Removing Virtual Volumes
X To remove a virtual volume and its unused underlying logical disks, issue the removevv
<VV_name>
command, where <VV_name> is the name of the virtual volume being
removed.
X If you wish to remove the virtual volume, but retain all of the volume’s underlying logical
disks, issue the
removevv -keepld <VV_name> command.
For a complete list of arguments that can be used with the
removevv command, see the
InForm OS Command Line Interface Reference.
7.10 Common Provisioning Groups
A common provisioning group (CPG) creates a "virtual pool" of logical disks that allows up to
64 volumes to share the CPG's resources and allocate space on demand.
NOTE: While it is possible for a CPG to have up to 64 volumes, it is strongly
recommended that no more than 32 volumes be associated with a single CPG. The
reasons for limiting this are as follows:
 Virtual volumes in the same CPG can share the same logical disk. In the unlikely
event that the logical disk is damaged (due to multiple simultaneous disk
failures, for example), all the volumes associated with that logical disk will be
unavailable.
 Virtual volume performance may suffer from too much interleaving within the
logical disks.
