3.Issue the HP 3PAR OS CLI showport -iscsicommand to check the current settings of the iSCSI ports:

#showport -iscsi

4.Issue the HP 3PAR OS CLI controliscsiport command to set up the IP address and netmask address of the iSCSI target ports.

#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: Make sure the IP switch ports where the HP 3PAR StoreServ Storage iSCSI target port(s) and iSCSI initiator host are connected are able to communicate with each other by using the vmkping command on the ESX host. (The VMware ESX host iSCSI initiator must be configured to perform this operation in accordance with “Configuring the Host for an iSCSI Connection” (page 65).)

To verify that the ESX host can see the HP 3PAR StoreServ Storage, use the vmkpingcommand:

#vmkping 10.1.1.100

To verify that the HP 3PAR StoreServ Storage can see the ESX host, issue the following command:

#controliscsiport ping 10.1.1.10 0:1:1

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 OS target port are in different IP subnets, the gateway address for the HP 3PAR OS port should be configured in order to avoid unexpected behavior.

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 18) and the steps in “Configuring the Host for an iSCSI Connection” (page 65) through “Configuring the VMware iSCSI Initiator” (page 72) (ESX host setup).
