iSCSI Protocol: Broadcom NetXtreme II® Network Adapter User Guide

file:///C|/Users/Nalina_N_S/Documents/NetXtremeII/English/iscsi.htm[9/5/2014 3:45:06 PM]

Linux iSCSI boot is supported on Red Hat Enterprise Linux 5.5 and later and SUSE Linux Enterprise Server 11 SP1 and later in
both the offload and non-offload paths. Note that SLES 10.x and SLES 11 have support only for the non-offload path.

1. For driver update, obtain the latest Broadcom Linux driver CD.
2. Configure the iSCSI Boot Parameters for DVD direct install to target by disabling the Boot from target option on the

network adapter.

3. Configure to install via the non-offload path by setting HBA Boot Mode to Disabled in the NVRAM Configuration.

(Note: This parameter cannot be changed when the adapter is in Multi-Function mode.). Note that, for RHEL6.2 and
SLES11SP2 and newer, installation via the offload path is supported. For this case, set the HBA Boot Mode to Enabled
in the NVRAM Configuration.

4. Change the boot order as follows:

a. Boot from the network adapter.
b. Boot from the CD/DVD driver.

5. Reboot the system.
6. System will connect to iSCSI target, then will boot from CD/DVD drive.
7. Follow the corresponding OS instructions.

a. RHEL 5.5 — Type "linux dd" at "boot:" prompt and press enter
b. SuSE 11.X — Choose installation and type withiscsi=1 netsetup=1 at the boot option. If driver update is

desired, choose YES for the F6 driver option.

8. If driver update is desired, follow the instructions to load the driver CD; otherwise skip this step.
9. At the "networking device" prompt, choose the desired network adapter port and press OK.

10. At "configure TCP/IP prompt", configure the way the system acquire IP address and press OK.
11. If static IP was chosen, you need to enter IP information for iscsi initiator.
12. (RHEL) Choose to "skip" media testing.
13. Continue installation as desired. A drive will be available at this point. After file copying is done, remove CD/DVD and

reboot the system.

14. When the system reboots, enable "boot from target" in iSCSI Boot Parameters and continue with installation until it is

done.

At this stage, the initial installation phase is complete. The rest of the procedure pertains to creating a new customized initrd
for any new components update:

1. Update iscsi initiator if desired. You will first need to remove the existing initiator using rpm -e.
2. Make sure all runlevels of network service are on:

chkconfig network on

3. Make sure 2,3 and 5 runlevels of iscsi service are on.

chkconfig -level 235 iscsi on

4. For Red Hat 6.0, make sure Network Manager service is stopped and disabled.
5. Install iscsiuio if desired (not required for SuSE 10).
6. Install linux-nx2 package if desired.
7. Install bibt package.
8. Remove ifcfg-eth*.
9. Reboot.

10. For SUSE 11.1, follow the remote DVD installation workaround shown below.
11. After the system reboots, log in, change to the /opt/bcm/bibt folder, and run iscsi_setup.sh script to create the offload

and/or the non-offload initrd image.

12. Copy the initrd image(s), offload and/or non-offload, to the /boot folder.
13. Change the grub menu to point to the new initrd image.
14. To enable CHAP, you need to modify iscsid.conf (Red Hat only).
15. Reboot and change CHAP parameters if desired.
16. Continue booting into the iSCSI Boot image and select one of the images you created (non-offload or offload). Your

choice should correspond with your choice in the iSCSI Boot parameters section. If HBA Boot Mode was enabled in the
