4 Allocating Storage for Access by the HP-UX Host
Creating Storage on the HP 3PAR StoreServ Storage
This section describes the general steps and commands that are required to create the virtual
volumes (VVs) that can then be exported for discovery by the HP-UX host.
For additional information, see the HP 3PAR Command Line Interface Administrator’s Manual. For
a comprehensive description of HP 3PAR OS commands, see the HP 3PAR Command Line Interface
Reference. See the HP Support Center to obtain a copy of this documentation.
Creating Virtual Volumes
Virtual volumes are the only data layer visible to hosts. After devising a plan for allocating space
for host servers on the HP 3PAR StoreServ Storage, create the virtual volumes.
After devising a plan for allocating space for the HP-UX host, you need to create the required
virtual volumes on the HP 3PAR StoreServ Storage.
You can create volumes that are provisioned from one or more common provisioning groups
(CPGs). Volumes can be fully provisioned from a CPG or can be thinly provisioned. You can
optionally specify a CPG for snapshot space for fully-provisioned volumes.
Using the HP 3PAR OS Management Console:
1. From the menu bar, select:
Actions→Provisioning→Virtual Volume→Create Virtual Volume
2. Use the Create Virtual Volume wizard to create a base volume.
3. Select one of the following options from the Allocation list:
• Fully Provisioned
• Thinly Provisioned
Using the HP 3PAR OS CLI:
To create a fully-provisioned or thinly-provisioned virtual volume, issue the following HP 3PAR OS
CLI command:
# createvv [options] <usr_CPG> <VV_name> [.<index>] <size>[g|G|t|T]
Here is an example:
# createvv -cnt 5 TESTLUNS 5G
NOTE: To create thinly-provisioned virtual volumes, an HP 3PAR Thin Provisioning license is
required.
Consult the HP 3PAR Management Console User’s Guide and the HP 3PAR Command Line Interface
Reference for complete details on creating volumes for the HP 3PAR OS version that is being used
on the HP 3PAR StoreServ Storage.

NOTE: The commands and options available for creating a virtual volume may vary for earlier
versions of the HP 3PAR OS.
