The configuration file for EFI boot setting has the following format:
[HBA0] ; section for each HBA
WWID=11223344 ; read-only variable
HostAdapterBiosEnable=1 ; input or current value when read from HBA
SelectBootEnable=1 ; input or current value when read from HBA
BootDeviceWWID=22334455 ; input or current value when read from HBA
BootDeviceLUN[0]=1111 ; input – default LUN; or current value when read from HBA |
The text file can be edited to insert the WWID of the boot volume and the LUN number that the HBA will boot from. The tool discovers the WWID of the HBA and writes the information to the text file. The text file will present the options in human readable format. The tool will update the hardware with the boot volume WWID and boot LUN read from the text file.
