Firmware Update - HPE ProLiant MicroServer Gen10 Series Troubleshooting Manual

Firmware update

Update the firmware (also called "flashing the ROM") as part of regular server maintenance. In addition,
check for specific firmware updates in between regular updates to help keep the server performing optimally.
Firmware updates are created for, but are not limited to, the following reasons:
• To provide critical problem fixes that ensure system stability, such as upgrades that might prevent server
unresponsiveness and other issues that could put the system at risk.
• To correct product issues, such as ROM or processor functionality.
• To improve system performance or make the system more serviceable.
Server downtime and time spent removing, returning, and ultimately replacing hardware might be avoided by
first updating the firmware during the troubleshooting process. Many product issues that result in hardware
replacement are preventable or correctable with a firmware update. Hewlett Packard Enterprise recommends
checking for a firmware update before sending a part back to Hewlett Packard Enterprise for replacement.
On servers that have add-on options, Hewlett Packard Enterprise recommends checking for firmware
upgrades for each installed option whenever an update to the system ROM or to another option is performed.
This ensures that the entire system is running the latest updates for each component.
Multiple methods exist to update the system ROM:
• EFI tool under Embedded UEFI Shell
• Online Flash components
Product entitlement is required to perform updates.
CAUTION:
Any kind of system interruption during the firmware update results in errors that might corrupt the BIOS
settings. These errors prevent the server from booting up. To prevent these update errors, observe the
following cautions:
• Attach a UPS to the server to provide backup power to the system when updating the firmware.
• Do not perform a forced shutdown of the server.
• Do not perform a forced closure of the firmware update tool.
Updating the system ROM using the EFI tool from within the Embedded UEFI Shell
For systems configured in UEFI boot mode, use the following procedure to update the firmware.
Procedure
1. Access the System ROM Flash component for your server from the Hewlett Packard Enterprise Support
Center website (http://www.hpe.com/support/hpesc) and save the package in a USB key.
2. Copy the file to a USB device.
3. Attach the USB device to the server.
4. To access the One-Time Boot Menu option, when prompted, press the F11 key.
5. Select UEFI: Built-in EFI Shell.
6. To obtain the assigned file system volume for the USB key, enter the map -r command at the UEFI
Shell prompt.
7. Change to the file system that contains the System ROM Flash Binary file that you downloaded for your
server. Enter one of the fsx file systems available, such as fs0 or fs1, and then press the Enter key.
If no other storage devices are mounted on the system, the USB drive is fs0: on the UEFI shell.
8. To change from the current directory to the directory that contains the binary file, enter the cd command.
