The Preboot menu provides the ability to recover the Oracle ILOM firmware image by updating (flashing) the SP firmware.
Normally, if the host is running, you can update the SP using the Oracle ILOM CLI or the web interface.
If the host is powered off and the SP firmware image becomes corrupted (making the server SP inaccessible using Oracle ILOM), you can use the following procedure to update it using the Preboot menu.
Before You Begin
To update the SP firmware, you must have the correct .pkg file, and a TFTP server that your server's SP can access over a network connection.
The .pkg file is part of the firmware package. For information about getting firmware packages, see Getting Server Module Firmware and Software.
For more information, refer to Accessing the Preboot Menu.
Preboot> net config
Preboot> net dhcp
This configures a DHCP network.
You need to be connected to a network that has access to the TFTP server.
Preboot> net ping tftpIPaddress
where tftpIPaddress is the IP address of a TFTP server.
This checks to see if the TFTP server is accessible over the network.
Preboot> net flash tftpIPaddress path/ ILOM-version-server.pkg
tftpIPaddress is the IP address of a TFTP server
path is the path to the file relative to /tftpboot
version is the version of SP firmware
server is the name of your server
Preboot> net flash 126.96.36.199 images/ILOM-3_0_x_x_rxxxx-Sun_Fire_X4800M2.pkg
This downloads and flashes the firmware image. After a series of messages, the Preboot prompt appears.
The Preboot menu exits and service processor reboots.
