Updating System Firmware

The system firmware on HP Integrity® systems is based on the Extensible Firmware Interface (EFI) specifications. You can use an EFI utility offline to verify the system firmware version installed on HP Integrity systems.

To determine the minimum recommended system firmware version for your system, see the SAS Host Bus Adapters Support Matrix at:

http://docs.hp.com/en/netcom.html

If the system firmware version installed on your system is lower than the minimum system firmware version required for the AH303A adapter to operate on that system, obtain the latest firmware updates from the Business Support Center at:

To find firmware updates, search for the model number of your server, then follow the links to download “Cross operating system (BIOS, Firmware, Diagnostics, etc.).” To install the update, follow the instructions provided in the download package.

Updating Adapter Firmware

Follow the procedures in this section to update the adapter firmware. For information on recommended firmware versions, see the SAS Host Bus Adapters Support Matrix at:

http://docs.hp.com/en/netcom.html

There are two methods to update the adapter firmware, depending on the HP-UX and SerialSCSI-00 versions installed on the server:

•In some SerialSCSI-00 bundle versions, the sasd driver updates the adapter firmware when the system boots.

•In later SerialSCSI-00 versions, the firmware is not updated by the driver. Use the sasflash EFI utility to update adapter firmware offline.

Table 1-3lists the method you must use to update the adapter firmware for each supported HP-UX and SerialSCSI-00 bundle version.
