For SAN boot with a SLES operating system, kernel parameter withiscsi=1
should be passed during installation.
Since this driver is based on Open-iSCSI, attempting to perform a SAN-boot
without these dependencies will fail.
To install the iSCSI driver:
1. Download the appropriate driver kit from the Emulex website.
2. Log in as “root” to a terminal, and unpack the tarball:
tar xzf elx-be2iscsi-dd-.tar.gz
3. Change to the directory that is extracted:
cd elx-be2iscsi-dd-/
4. Run the elx_iscsi_install.sh script with no options to install the driver kit:
./elx_iscsi_install.sh
5. Once the elx_iscsi_install script has finished running successfully:

For an iSCSI boot case, you must reboot the system now to load the driver.

For all other iSCSI cases, the Emulex iSCSI driver is loaded, and devices that are
connected to the system are accessible. Reboot the system now to enable the
newly added driver options in the ramdisk. You can also reboot the system
later.
Uninstalling the iSCSI Driver Kit
Note: You must run the uninstall script that shipped with the version of the driver kit
you want to remove.
To uninstall the iSCSI driver:
1. Log in as “root”.
2. If possible, exit all applications that use iSCSI-attached drives, then unmount the
drives. If you cannot exit all applications that use iSCSI-attached drives, the
uninstall works properly, but you must reboot after the uninstallation is complete.
3. Run the elx_iscsi_install.sh script with the “--uninstall” option:
./elx_iscsi_install.sh --uninstall

To configure SLES 11 SPx to boot from an FC-attached disk device other than
/dev/sda, see the Emulex Boot for the Fibre Channel Protocol User Manual, which is
available on the Emulex website.
