6 Allocating Storage for Access by the SUSE 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 (VV) that can then be exported for discovery by the SUSE host. For additional information,

see the HP 3PAR Command Line Interface Administrator’s Manual, which is available on the HP

SC website:

Creating Virtual Volumes

Virtual volumes (VVs) are the only data layer visible to hosts. After devising a plan for allocating

space for the SUSE host, you need to create the required VVs 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 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.

These documents are available on the HP SC website:

HP Support Center

NOTE: The commands and options available for creating a virtual volume may vary for

earlier versions of the HP 3PAR OS.
