HP 3PAR VMware ESX Implementation Guide

2 Configuring the HP 3PAR StoreServ Storage for Fibre
Channel
This chapter explains how to establish a Fibre Channel connection between the HP 3PAR StoreServ
Storage and a VMware ESX host and covers HP 3PAR OS 3.1.x and 2.3.x versions. For information
on setting up the physical connection for a particular HP 3PAR StoreServ Storage, see the
appropriate HP 3PAR installation manual.
Configuring the HP 3PAR StoreServ Storage Running HP 3PAR OS 3.1.x
or OS 2.3.x
This section describes how to connect the HP 3PAR StoreServ Storage to an ESX host over an FC
network when running HP 3PAR OS 3.1.x or OS 2.3.x.
By default, the QLogic, Emulex, and Brocade drivers for the VMware ESX host support failover.
For failover support using the QLogic, Emulex, or Brocade driver, virtual volumes should be
simultaneously exported down multiple paths to the host. To do this, create a host definition on the
HP 3PAR StoreServ Storage that includes the WWNs of multiple HBA ports on the host and then
export the VLUNs to that host definition. Each ESX/ESXi host within a cluster must have its own
host definition and shared VLUNs must be exported to each of the host definitions of the cluster.
Required
The following setup must be completed before connecting the HP 3PAR StoreServ Storage port to
a device.
NOTE: When deploying HP Virtual Connect Direct-Attach Fibre Channel storage for HP 3PAR
StoreServ 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,
follow the steps for configuring the HP 3PAR StoreServ Storage ports for a fabric connection.
For more information about HP Virtual Connect, HP Virtual Connect interconnect modules, and the
HP Virtual Connect Direct-Attach Fibre Channel feature, see HP Virtual Connect documentation.

Setting Up the Ports
Before connecting the HP 3PAR StoreServ Storage to a host, the connection type and mode must
be specified. To set up the HP 3PAR StoreServ Storage ports for a direct or fabric connection,
complete the following steps for each port.
1. To determine if a port has already been configured in host mode, issue the HP 3PAR OS CLI
showport -par command. A host port is essentially a target mode port where the initiator
or host can log in to the HP 3PAR StoreServ Storage.
