HP 3PAR VMware ESX Implementation Guide

4. On your HP 3PAR StoreServ Storage array, issue 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, the gateway address for the HP 3PAR StoreServ Storage iSCSI port
should be configured in order to avoid unexpected behavior by issuing controliscsiport
gw <gw_address> [-f] <node:slot:port>.
5. If you haven’t already done so configure your ESX host iSCSI initiator in accordance with
“Configuring the Host for an iSCSI Connection” (page 64).
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. Prior to
creating a host definition using the following steps, the HP 3PAR StoreServ Storage iSCSI target
ports must have been set up and an iSCSI connection/session must be established. The iSCSI
connection/session 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 64)
through “Configuring the VMware SW iSCSI Initiator” (page 73) (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), which enables asymmetric
logical unit access (ALUA) is available.
◦ 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.
