8. Configure one port of network adapter to connect to iSCSI Target (see how to setup iSCSI target in corresponding
section).
9. Connect to iSCSI Target.
10. Use DD command to copy local hard drive to iSCSI Target.
11. When DD is done, execute sync command a couple of times, logout then login to iSCSI Target again.
12. Run fsck command on all partitions created on iSCSI Target.
13. Change to /OPT/bcm/bibt folder and run the iscsi_setup.sh script to create the initrd images. Option 0 will create non-
offload image and option 1 will create offload image. Iscsi_script.sh script will create the non-offload image only on
SuSE 10 as offload is not supported on SuSE 10.
14. Mount the /boot partition on the iSCSI Target.
15. Copy the initrd images you created in step 13 from your local hard drive to the partition mounted in step 14.
16. On the partition mounted in step 14, edit grub menu to point to the new initrd images.
17. Unmount the /boot partition on the iSCSI Target.
18. (Red hat Only) To enable CHAP, you need to modify the CHAP section of the iscsid.conf file on the iSCSI Target. Edit
iscsid.conf file with one or two way CHAP information as desired.
19. Shut down system and disconnect local hard drive. Now you are ready to iSCSI boot into iSCSI Target.
20. Configure iSCSI Boot Parameters including CHAP parameters if desired (see corresponding sections).
21. Continue booting into iSCSI Boot image and choose 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 iSCSI
Boot Parameters section, you have to boot the offload image. SuSE 10.x and SLES 11 do not support offload.
Remote DVD installation
Installation using the remote DVD method can only be performed through the non-offload path. After completing the
installation, the system can be setup to boot from either the non-offload or offload paths as described in the procedure below.
Starting with Red Hat 6.2 and SLES 11.2, installing through the offload path will be supported.
1. Get the latest Broadcom Linux driver CD.
2. Configure iSCSI Boot Parameters for DVD direct install to target by disabling Boot from target option on network
adapter.
3. To set to the non-offload path, set HBA Boot Mode to
Disabled
in the NVRAM Configuration.
4. Change 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. Red Hat 5.5 - Type "linux dd" at "boot:" prompt and press enter
b. Red Hat 6.0
c. SuSE 10
d. SuSE 11.1 choose "installation" and type withiscsi=1 netsetup=1 at boot option and choose YES for F6 driver
option.
8. Follow the instructions to load the driver CD.
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. (Red hat) 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 system.
14. When system reboot, enable "boot from target" in iSCSI Boot Parameters and continue with installation until it is done.
15. Update iscsi initiator if needed. You need to remove existing one first.
