EMC QLogic manual Unload 5D

Configuring an EMC Boot Device

If a system contains of mixture of detected and undetected adapters, any existing

EFI drivers loaded by EFI should be unloaded using the EFI Shell drivers, and unload commands. If you have not previously installed EFI boot code to your QLogic HBA, skip this section.

1.Type drivers at the EFI shell prompt to display the list of loaded EFI drivers. You will see an entry (or entries) similar to the following:

5D	0000011E	B	X	X	1	HP 2 Gb Fibre Channel Driver	PciRom	Seg=00000000
5D	00000140	D	X	X	1	- Qlogic Fibre Channel Driver	PciRom	Seg=00000000

2.The first column (in this example, 5D) is the driver handle for the HBA. To unload the EFI boot code driver, use the unload command:

unload 5D

3.After all instances of the QLogic EFI boot code driver are unloaded, proceed to the next section.

To flash the HBA with the latest EFI boot code, copy the files from the EFI boot code package to a floppy disk. If your system does not have a floppy drive, a USB pen drive can be used instead. If your system is already booted to the EFI shell, insert the floppy or USB pen drive and type exit to exit the EFI shell. From the boot options menu, select EFI Shell [Built-in]to go back into the EFI shell. This will cause the EFI shell to re-discover disk devices and will locate the floppy or pen drive.

When you enter the EFI shell, the device map should be displayed. If it does not display, type map at the shell> prompt to display the list of detected devices. Disk devices that are accessible by the EFI shell are listed as FS devices. Switch to the device containing the EFI boot code. This is accomplished by typing the name of the device and a colon. For example, if the EFI boot code is on fs1, type fs1: and press ENTER to switch to that device. If your HBA does not have EFI boot code already installed, you must use the EFIUTIL.EFI driver utility in order to flash the board. At the command prompt, type EFIUTIL and press ENTER. This will load the QLogic EFI utility and display a efiutil> prompt. The following commands assume that the EFI boot package files are all located in the same directory as the EFIUTIL.EFI program.
