Fibre Channel cards◦
◦ SAS HBA cards

• SAS controller firmware
• SAS HDD firmware
• LOM firmware
System firmware and iLO 3 firmware must be from the same release. Independent updates are not
supported. Details about a specific release are available in the associated Release Notes.
Firmware updates are available from the HP website at http://www.hp.com under "Support and
Drivers".
Identifying and troubleshooting firmware issues
Erratic system operation, or the fact that the server might not boot successfully to the UEFI Boot
Manager or to the UEFI Shell, are symptoms of possible firmware issues.
Firmware issues are relatively rare, and, therefore, look for other causes first.
If you are attempting to resolve a firmware issue, the possible failure areas are as follows:
• Unsupported firmware installation
• Corrupt firmware installation
To troubleshoot firmware issues:
1. Verify that all system and iLO firmware components are from the same release (use the iLO 3
sr command).
2. Reinstall all firmware.
IMPORTANT: If firmware reinstallation does not resolve the issue, processor or system board
replacement might be required.
Updating firmware
System firmware updates are available from the HP Business Support Center:

To update your firmware:
1. To determine the current system firmware and iLO firmware versions, use the iLO sr command.
