8 Allocating Storage for Access by the ESX Host
This chapter describes the basic procedures that are required to create and export virtual volumes
so they can be utilized by the VMware ESX host. For complete details on creating and managing
storage on the HP 3PAR StoreServ Storage, consult the appropriate HP 3PAR documentation.
Creating Storage On the HP 3PAR StoreServ Storage
This section describes the general recommendations and restrictions for exporting storage from the
HP 3PAR StoreServ Storage to an ESX host.
Consult the HP 3PAR Management Console Users Guide and the HP 3PAR Command Line Interface
Reference for complete details on creating virtual volumes for a given HP 3PAR OS. In addition,
for a detailed discussion on using thinly-provisioned virtual volumes and strategies for creating
VLUNs, consult 3PAR Utility Storage with VMware vSphere.
To obtain a copy of this documentation, see the HP BSC website:

NOTE: To create thinly-provisioned virtual volumes, an HP 3PAR Thin Provisioning license is
required.
Creating Virtual Volumes for HP 3PAR OS 2.2.4 and Later
After devising a plan for allocating space for the ESX host, you need to create the required virtual
volumes on the HP 3PAR StoreServ Storage. Volumes can be fully provisioned from a CPG or can
be thinly provisioned.
Using the HP 3PAR Management Console:
1. From the Menu bar, select:
Actions→Provisioning→Virtual Volume→Create Virtual Volumes
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 -tpvv -cnt 5 TESTLUNs 5g
