From the EFI Shell> prompt, enter the exit command and the boot manager screen appears.

From the boot manager screen, select Device Manager, see Figure 2-3.

From the Device Manager screen, as shown in Figure 3-1, select iSCSI Configuration.

Enable iSCSI on the port (see Figure 3-5). If you are using DHCP to get your initiator's IP address, enable DHCP, otherwise enter the Initiator's IP address, Subnet address and Gateway. Also enter the Target Name of the iSCSI target along with the IP address of the Target. Then enter the Target Port and Boot LUN. Save your changes.

Reboot the BIOS. On reboot your iSCSI target will show up in the EFI map (fs0 in this example):

In order to boot from a Qlogic Fibre Channel disk on an SGI Altix UV 100 or SGI Altix UV 1000 system, the ProcessEfiOpRoms EFI environment variable needs to be set. Use the EFI set command, as shown in Figure 3-7.

Note: You need to reset the BIOS for the variable change to take affect.

Use the EFI drivers command to verify that the QLogic Fibre channel driver is being loaded after the EFI reset, as shown in Figure 3-8.

A disk needs to have a bootable partition in order to show up as an fs # entry in the EFI map. If it does not have a bootable partition it will show up as a blk# entry. You can use the map command to verify fs0 is booting the system from Fibre channel disk.

The EFIUtilx64.efi command can be used to configure Qlogic Fiber Channel to EFI boot. The EFIUtilx64.efi utility can be downloaded from http://www.qlogic.com/Pages/default.aspx . Figure 3-10 shows the EFIUtilx64.efi utility.

The change to the ProcessEfiOpRoms EFI environment variable is persistent as the system is rebooted. To clear it, use the set -d option, as follows:

Shell>  set -d ProcessEfiOpRoms
Shell>  reset

You can also clear the EFI variables from either the CMC or BMC, as follows:

cmc>power -c
