3. Install a Linux operating system over the iSCSI LUN. For more information refer to
the Emulex Driver for Linux User Manual, which is available on the Emulex website.
For iSCSI boot, you will need the following information:
For RHEL operating systems:
a. When running the vmlinuz command, include the dd parameter to indicate that
a driver update will be done.
b. When prompted for the type of device your installation involves, choose
“Specialized Storage Devices”.
c. When prompted to select the drives on which you will install the operating
system or any drives you want to automatically mount to the system, select the
iSCSI target device on the “Other SAN Devices” tab.
For SLES operating systems:
a. Set withiscsi=1 to indicate that a driver update will be done.
b. When prompted, click Configure iSCSI Disks to perform target login.
Note: You may need to run certain iscsiadm commands to load the disk after the
iSCSI driver is installed. See the iscsiadm documentation for additional
information.
4. Once Linux is installed, install the MPIO software and reboot the system.
5. After rebooting, ensure that the boot LUN is detected by the MPIO driver. Perform
either of the following steps:

To see if the multipath is running, type:
# /sbin/multipath
-or-

To see if the multipath daemon is running, type:
# ps -aelf | grep multipathd
6. If multipath is running, you can view the current multipath topology. To view the
current multipath topology, type:
# /sbin/multipath -l
7. Reboot your system and log into the iSCSISelect utility by pressing when
prompted.
8. Use the iSCSISelect utility to add an additional boot path to the same iSCSI LUN. To
do this, follow these steps:
a. Follow the steps for the “Linux and Citrix Servers” on page 1573 to set up the
second path.
b. When you get to the Add/Ping iSCSI Target menu, make sure you set a valid
ISID Qualifier before adding your target. For more information on the ISID
Qualifier, see “Setting an ISID Value” on page 1616.
c. After you have logged into the target, from the iSCSI Target Configuration
menu, set the Boot Target option for the second target to Yes.
d. Press to display the LUNs behind the target.
