HP 3PAR RedHat and Oracle Linux Implementation Guide

To set up a hardware iSCSI host definition, see “Setting Up Hardware iSCSI for RHEL 6 or RHEL
5” (page 60).
NOTE: If multiple initiator ports are used, add the following to /etc/sysctl.conf:
net.ipv4.conf.all.arp_filter = 1
NOTE: To be able to establish an iSCSI Initiator connection/session with the iSCSI target port
from the host, you must create a host definition entry, create the iSCSI host definition, and configure
the HP 3PAR StoreServ Storage iSCSI target port(s).
For details, see “Creating the Software iSCSI Connection in RHEL 6 or RHEL 5 Using the iscsiadm
Command” (page 79).
To get the software iSCSI initiator name, issue the following command on the host:
# cat /etc/iscsi/initiatorname.iscsi
Initiator Name=iqn.1994-05.com.redhat:a3df53b0a32dS
To get the hardware iSCSI initiator name for Emulex CNAs, press Ctrl-S through the BIOS, the
hbacmd utility, or the ocmanager UI:
# hbacmd GetInitiatorProperties 28-92-4a-af-f5-61
Initiator login options for 28-92-4a-af-f5-61:
Initiator iSCSI Name: iqn.1990-07.com.emulex:28-92-4a-af-f5-61
See “iSCSI Commands” in the OneCommand™Manager Command Line Interface Version 6.1
User Manual, which is available at the following website:
Emulex
1. To configure 10 G iSCSI on the host, Use the Emulex OneCommand Manager command
/usr/sbin/ocmanager/hbacmd or the QLogic QConvergeConsole Manager command
/opt/QLogic_Corporation/QConvergeConsoleCLI/qaucli to find the MAC address
for the 10 Gb CNA, and then assign an IP address to the 10 Gb NIC port.
NOTE: Currently, hardware iSCSI is supported only on the following models: only HP
NC551/553/FlexFabric 554/CN1100E support hardware iSCSI
• HP NC551
• HP NC553
• HP FlexFabric 554
• HP CN1100E
