HP 3PAR RedHat and Oracle Linux Implementation Guide

6 Configuring a Host with iSCSI
Setting Up the Switch and iSCSI Initiator
Connect the Linux host iSCSI initiator port(s) and the HP 3PAR StoreServ Storage iSCSI target ports
to the switch(es).
If you are using VLANs, make sure that the switch ports which connect to the HP 3PAR StoreServ
Storage iSCSI target ports and iSCSI initiator ports reside in the same VLANs and/or that you can
route the iSCSI traffic between the iSCSI initiator ports and the HP 3PAR StoreServ Storage iSCSI
target ports. Once the iSCSI initiator and HP 3PAR StoreServ Storage iSCSI target ports are
configured and connected to the switch, you can use the ping command on the iSCSI initiator
host to make sure it sees the HP 3PAR StoreServ Storage iSCSI target ports.
NOTE: Setting up the switch for VLAN and routing configuration is beyond the scope of this
document. Consult your switch manufacturer's guide for instructions about setting up VLANs and
routing.
The procedures in this chapter assume that you have completed the following tasks:
• Set up and configuration of the host Network Interface Card (NIC) or converged network
adapter (CNA) as Initiator port that will be used by the iSCSI Initiator software to connect to
the HP 3PAR StoreServ Storage iSCSI target ports.
• Installation of the iSCSI initiator software package.
Configuring RHEL 6 or RHEL 5 for Software and Hardware iSCSI
This section describes the procedures for setting up an RHEL software/hardware iSCSI configuration
with an HP 3PAR StoreServ Storage. Figure 3 (page 57) shows an iSCSI topology.
