ONIE-based firmware update
NOTE:
Always update the ONIE operating system first. After this update finishes, update the firmware, such as the BIOS,
CPLD, FPGA, and so forth.
NOTE:
The output examples are for reference only. Your output may vary.
You can update the firmware by using any of the following methods:
● Firmware update invoked manually from ONIE
● Firmware update using the USB
● Firmware update staging from NOS
● Firmware update staging from ONIE
WARNING:
Do not power cycle or power off your switch when you upgrade the CPLD image.
WARNING:
The FW-updater program updates the switch as needed.
NOTE:
Upgrading the CPLD may take up to 10 minutes.
NOTE:
After you have successfully upgraded, the FW-updater program power-cycles the switch.
Firmware update invoked manually from ONIE
Manually invoke the firmware update from the ONIE prompt using the onie-self-update command.
NOTE:
This method allows you to update the firmware components in one step without requiring a system reboot.
However, this method is not supported for platforms supporting the multistage reboot sequence.
1. Boot into Rescue mode.
2. Copy the firmware update binary to the target using the onie-self-update command.
This step starts the firmware update process.
ONIE:/ # onie-self-update onie-firmware-x86_64-VENDOR_MACHINE -r0.bin
Verify firmware update
After you have updated the firmware, verify that all components—BIOS and CPLD, are running the correct version.
● To check the BIOS version, use the dmidecode -s system-version command. The BIOS version also displays during
system bootup.
● To check the CPLD version, use the showSystemInfo command at the DCLI prompt.
Firmware update using Discovery
This method is the preferred mode for updating the firmware in Fully Automatic mode.
Using the Discovery feature to update your firmware is the best option for data centers. Boot your system in ONIE Update
mode. Do this using the automation tool you have on your system to avoid logging in to each system to select onie-update
as the next boot mode. After the systems boot to ONIE Update mode, the Discovery feature locates the ONIE firmware binary.
Copy the binary to any TFTP, FTP, or HTTP server reachable over your network.
NOTE:
Be sure to rename the ONIE firmware binary the same name as the onie-self-updater image name. ONIE Discovery
in Self-Update mode locates the ONIE self-update image, and while processing the image, determines that it is the firmware
updater image. In this order, ONIE looks for these default updater file names:
1. onie-updater-<arch>-<vendor>_<machine>-r<machine_revision>
2. onie-updater-<arch>-<vendor>_<machine>
3. onie-updater-<vendor>_<machine>
4. onie-updater-<arch>
