By using the below Powersell script we can update the Onboard Administrator firmware.
We need HP Powershell cmdlet to run this script and download the same from the below link.
To run this script we need Update-HPOAFirmware cmdlet.
The Update-HPOAFirmware cmdlet downloads a new flash image from the network and uses it to update the Onboard Administrator firmware. If a standby Onboard Administrator is present in the system, then this command flashes and validates its
firmware before attempting to flash the active Onboard Administrator.
A list of connection objects must be provided as a parameter. OA administrator or OA operator access is required to execute this cmdlet.
Warning. It takes several minutes to complete the operation. OA is restarted when the firmware update is complete, so the OA connection will be lost, It will be necessary to reconnect OA for the additional operations.
Download the script from the below location.
