Linux iSCSI Boot Setup
Linux iSCSI boot is supported on Red Hat Enterprise Linux 5.5 and later and
SUSE Linux Enterprise Server 11 (SLES 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.
To set up Linux iSCSI boot:
1. For driver update, obtain the latest QLogic 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 through 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
RHEL 6.2, installation through 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 or DVD driver.
5. Reboot the system.
The system will connect to iSCSI target, and then will boot from the CD or
DVD drive.
6. For SUSE 11.x, choose installation and type with iscsi=1 netsetup=1 at
the boot option. If driver update is required, choose YES for the F6 driver
option.
7. At the networking device prompt, choose the required network
adapter port, and then click OK.
8. At the configure TCP/IP prompt, configure the way the system acquire
IP address, and then click OK.
9. If static IP was chosen, you must enter IP information for iSCSI initiator.
10. (RHEL) Choose to “skip” media testing.
11. Continue installation as needed. A drive will be available at this point. After
file copying is done, remove the CD or DVD and reboot the system.
12. 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.
