HP 3PAR VMware ESX Implementation Guide

4. On your HP 3PAR StoreServ Storage array, use the controliscsiport command to
configure networking as shown in the following example:
# controliscsiport addr 10.1.1.100 255.255.255.0 -f 0:1:1
# controliscsiport addr 10.1.1.102 255.255.255.0 -f 0:1:1
# controliscsiport addr 10.1.1.101 255.255.255.0 -f 0:1:2
# controliscsiport addr 10.1.1.103 255.255.255.0 -f 0:1:2
NOTE: A maximum of 64 host iSCSI initiator ports can be connected to any one HP 3PAR
StoreServ Storage target port.
NOTE: When the host initiator port and the HP 3PAR StoreServ Storage iSCSI target port
are in different IP subnets, configure the gateway address for the HP 3PAR StoreServ Storage
iSCSI port to avoid unexpected behavior as follows:
controliscsiport gw <gw_address> [-f] <node:slot:port>
5. If you have not already done so, configure your ESX host iSCSI initiator in accordance with
“Configuring the Host for an iSCSI Connection” (page 62).
6. From your ESX host use the vmkping command to verify communication with your HP 3PAR
StoreServ Storage iSCSI target ports as shown in the following example:
# vmkping 10.1.1.100
7. From your HP 3PAR StoreServ Storage array use the controliscsiport command to verify
communication with your ESX host initiator ports as shown in the following example:
# controliscsiport ping 10.1.1.10 0:1:1
Creating the iSCSI Host Definition on an HP 3PAR StoreServ Storage Running HP 3PAR
OS 3.1.x and OS 2.3.x
Create a host definition that ties all of the connections from a single host to a host name. Before
creating a host definition, the HP 3PAR StoreServ Storage iSCSI target ports must be set up and
an iSCSI connection established. The iSCSI connection is established by following the steps in
“Setting Up the Ports for an iSCSI Connection” (page 15) and the steps in “Configuring the Host
for an iSCSI Connection” (page 62) through “Configuring the VMware SW iSCSI Initiator” (page 71)
(ESX host setup).
• ESX/ESXi uses the generic legacy host persona of 6 for HP 3PAR OS 3.1.1 or earlier.
• As of HP 3PAR OS 3.1.2, a second host persona 11 (VMware) enables asymmetric logical
unit access (ALUA).
◦ Host persona 11 (VMware) is recommended for new ESX/ESXi installations and is required
for ESX/ESXi hosts configured as part of a HP 3PAR Peer Persistence configuration.
• ESX/ESXi hosts performing HP 3PAR single volume Peer Motion is required to use 3PAR OS
3.1.3 or later and host persona 11.
• For ESX/ESXi hosts with HP 3PAR Remote Copy, see the Remote Copy Users Guide for the
appropriate host persona to use in specific Remote Copy configurations. This document is
available on the HP Storage Information Library at: www.hp.com/go/storage/docs
• Host Persona 6 will not be supported for any version of VMware ESX with 3PAR OS versions
after 3PAR OS 3.1.3 and its MUs. HP recommends that customers migrate their ESX
configurations on 3PAR to Host Persona 11 with 3PAR OS 3.1.2 or later.
