Upgrading a component's firmware

The Firmware Management Tool (FMT) is a CLI based tool that is used to display active firmware

versions, show recommended firmware updates, and perform firmware updates for the currently

selected server blade. You must log in to each server blade to display its firmware information.

NOTE: Some firmware applies to the system enclosure or storage and is not specific to either

server blade. Firmware updates of this type can only be flashed from server blade1 of the storage

system by default when the Check and Update Firmware script is executed. If you attempt to flash

firmware that is not specific to the server blade from server blade 2, it will not work unless you use

the -ignorerole option with the flash command.

Firmware updates are typically required after installing a software patch that includes firmware

updates for the hardware. When the patch is downloaded and installed, new firmware components

are copied to the system but are not installed automatically.

Before performing a firmware upgrade, remember the following:

• You must complete these steps on each server blade.

• You must run the Check and Update Firmware script to determine which system components

require an upgrade. The script checks for recommended firmware updates and will either

indicate if an update is required or if the firmware is current.

• Consider performing an upgrade during a scheduled maintenance period or during periods

of low user activity.

• Some hardware components cannot be upgraded until a particular component is upgraded

first. For example, if the disk enclosure I/O module component requires an upgrade, the

HP1210m controller must be upgraded first. In this case you would have to reboot the server

blade.

• The script updates the components in the sequential order of server, storage, and chassis. If

the upgrade for a component fails, the script continues with the next component upgrade.

• The script only performs upgrades on the components that require one. It does not perform

downgrades, even if a downgrade is listed as the required action. If a firmware downgrade

is necessary, contact HP Support for assistance to ensure system integrity is maintained.

IMPORTANT: Always check the firmware flash recommendation output before beginning an

update. It provides important information on how the update may impact system operation (for

example, reboot required or coordinated reboot). If a coordinated reboot is required, see

“Performing a coordinated reboot” (page 75) for more information.

To update firmware:

1. On server blade 1, select Check and Update Firmware and follow the prompts that display.

2. If the system requires an update, the following prompt is displayed:

Press Y to flash firmware now, or any other key to skip.

Enter y or Y to proceed with upgrading the firmware, or select any other key to skip the

upgrade and exit.

When you proceed with the upgrade, the following components on server blade 1 will be

upgraded:

NOTE: The component names listed match the device names that display in the FMT.

• Enclosure Management Unit (EMU)

• Expander IO Module

• Enclosure IO Module
