iLO network Failed Flash Recovery
Most firmware upgrades finish successfully. In the unlikely event of server power loss during an
iLO firmware upgrade, iLO might be recoverable when power is restored.
When the iLO starts, the startup code performs image validation on the main image. If the image
is corrupted or incomplete and it cannot be recovered automatically with the Secure Recovery
feature, iLO enters Failed Flash Recovery mode. Failed Flash Recovery activates an FTP server
within iLO. The FTP server enables you to send an image to iLO for programming. The FTP server
does not provide any other services.
This feature is available only if iLO is configured to use the Production security state.
A network client can connect to the FTP server. The user name for the connection is test, and the
password is flash. To send a firmware image to iLO, use the FTP client PUT command. After
receiving the image, iLO validates the image. If the image is a complete, signed, and valid
firmware image, the kernel begins programming the FLASH partition.
After the image is programmed into the FLASH partition, reset iLO by issuing the RESET
command to the iLO FTP server.
