Fibre Channel Host Bus Adapters Offline Driver and Firmware Updates

The Extensible Firmware Interface (EFI) is an Itanium-based preboot environment used to update the EFI

driver and firmware on the adapter. EFI can be used in either command-line interface mode or batch mode.

The following example demonstrates the use of the efiutil command-line interface stored on a CD to update

an EFI driver:

1. From the EFI prompt, enter the map -r command.

2. Enter the cd command to change to the directory containing efiutil.

3. Enter the efiutil command to get to the command line interface for efiutil.

4. Choose the adapter you want to update as shown below:

efiutil> adapter

Adapter Index number [0]?

<n>

Where:

<n> represents the adapter index you want to update.

5. To update the EFI driver, enter the following command:

efiutil> efi_write=

6. To update the card firmware, enter the following command:

efiutil> risc_fw_write=

7. After the update process is complete, reset the system by entering the following command:

fsx:\>

reset
