Creating the Host Definition
Before connecting the ESX host to the HP 3PAR StoreServ Storage, create a host definition for each
HP 3PAR StoreServ Storage that is to be connected to a host HBA port through a fabric or a direct
connection.
1. To create host definitions, issue the HP 3PAR OS CLI createhost command with the
appropriate host name. For example:
# createhost ESXserver1 10000000C9724AB2 10000000C97244FE
2. To verify that the host has been created, issue the HP 3PAR OS CLI showhost command.
# showhost -persona
Id Name -WWN/iSCSI_Name- Port
0 ESXserver1 10000000C9724AB2 ---
10000000C97244FE ---
3. (Optional) You can create a host set using createhostset, which allows the addition of
multiple host names as a host definition set. A host set gives the convenience of exporting
storage volume to hosts which are in a cluster. The same storage volumes need to be exported
individually to each of the hosts, or they can be exported to a host set, which in turn will be
exported to each of the hosts defined in the host set.
# createhostset ESXCluster
# createhost -add ESXCluster ESXserver1
# createhost -add ESXCluster ESXserver2
# showhostset
Id Name Members
0 ESXCluster ESXServer1 ESXServer2
NOTE: See the HP 3PAR Command Line Interface Reference or the HP 3PAR Management
Console Users Guide for complete details on using the controlport, createhost, and
showhost commands.

Setting Up and Zoning the Fabric
NOTE: This section does not apply when deploying HP Virtual Connect direct-attach FC storage
for HP 3PAR storage systems, where the HP 3PAR StoreServ Storage ports are cabled directly to
the uplink ports on the HP Virtual Connect FlexFabric 10 Gb/24-port Module for c-Class
BladeSystem. Zoning is automatically configured based on the Virtual Connect SAN Fabric and
server profile definitions.
For more information about HP Virtual Connect, HP Virtual Connect interconnect modules, and the
HP Virtual Connect direct-attach feature, see HP Virtual Connect documentation and the HP SAN
Design Reference Guide. This documentation is available on the HP BSC website:

Fabric zoning controls which Fibre Channel end-devices have access to each other on the fabric.
Zoning also isolates the hostand HP 3PAR StoreServ Storage ports from Registered State Change
Notifications (RSCNs) that are irrelevant to these ports.
