HP 3PAR InForm OS 3.1.1 CLI Administrator's Manual

For instructions on creating domain CPGs, see “Moving a Common Provisioning Group to a
Domain” (page 99). For more information about virtual domains, see the HP 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.
◦ <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 HP 3PAR InForm
OS Command Line Interface Reference and InForm OS CLI Help.
Modifying Virtual Volumes in Domains
Domain virtual volumes can be modified just as virtual volumes in systems without domains can
be modified.
• If you are Super or Edit 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.
• If you are an Edit user belonging to a specified domain, all options for the setvv command
are available for use for virtual volumes that belong to the same specified domain.
Refer to the HP 3PAR InForm OS Concepts Guide and the setvv command in the HP 3PAR InForm
OS Command Line Interface Reference for additional information about this restriction.
• To modify a virtual volume in a domain, see “Modifying Virtual Volumes” (page 88).
Growing Virtual Volumes in Domains
Existing domain virtual volumes can be enlarged (grown) by automatically adding capacity
increments that you specify. Volumes which were created by Super or Edit users in the all domain
can only be grown by Super or Edit users in the all domain. Volumes created from CPGs by Edit
users in a specified domain can be grown by those users.
• For instructions on growing domain virtual volumes, see “Growing Virtual Volumes” (page 88).
Freeing Virtual Volume Snapshot Space in Domains
The snapshot space in virtual volumes belonging to domains can be made available just as virtual
volumes in systems without domains.
• For instructions on freeing virtual volume snapshot space, see “Freeing Virtual Volume Snapshot
Space” (page 91).
Exporting Virtual Volumes in Domains
Creating VLUN templates in domains is procedurally no different from creating VLUN templates
in systems that do not use virtual domains. If you are using virtual domains, you can export virtual
volumes in your domains. The right to perform inter-domain exports is determined by the user’s
role.
• Super and Edit users belonging to the all domain can export virtual volumes in any domain
existing in the system.
• Edit users belonging to a specified domain can only export virtual volumes to hosts
belonging to that domain.
