3PAR InForm CLI Administrator’s Manual InForm OS Version 2.3.1
All arguments are identical to those specified in 7.4 Creating a Common Provisioning Group on
page 7.6. For a complete list of options available for the
createcpg command, see the InForm
OS Command Line Interface Reference and InForm CLI Help.
7.20.2 Creating Virtual Volumes in a Virtual Domain
If you are using 3PAR Virtual Domains, you can create domain-specific virtual volumes which
are accessible only by those users with privileges to that domain. You must have super or edit
level user privileges in the domain in which you are creating the virtual volume. Virtual
volumes are created by allocating resources from CPGs within a domain. A CPG must exist in
the domain in which you wish to create a virtual volume before you can create a domain-
specific virtual volume.
For instructions on creating domain CPGS, see 7.20.7 Moving a Common Provisioning Group to
a Domain on page 7.28. For more information about 3PAR Virtual Domains, see the 3PAR
InForm OS Concepts Guide.
 To create a virtual volume within a domain, issue the createvv <usr_CPG> <VV_name>
<VV_size
g|G|t|T> command, where:
◆ <usr_CPG> is the name of the CPG from which the created virtual volume’s user space
is drawn.
◆ <usr_CPG> is the name of the domain-specific CPG from which the created virtual
volume’s user space is drawn. For instructions on creating domain CPGs, see 7.20.7
Moving a Common Provisioning Group to a Domain on page 7.28.
◆ <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.
7.20.3 Modifying Virtual Volumes in Domains
Domain virtual volumes can be modified just as virtual volumes in systems without domains
can be modified. However, some restrictions apply to domain virtual volume modification.
■ If you are super or edit level user belonging to the all domain, all virtual volume
modification options for the
setvv command are available for use and you can modify any
virtual volume in the system.
