If you were previously in ONIE Update mode and stopped discovery using the onie-stop command, restart discovery using
the onie-start command. This command causes the ONIE firmware updater infra to locate the firmware updater binary
image and proceed with the firmware update.
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 if you are using Dell DIAGs. Or use the
cpldupgradetool --cpldver command if you are using EDA-DIAGs.
Firmware update using USB
ONIE Discovery can locate a valid self-updater image in a USB.
1. Rename the firmware updater image so that it matches the onie-self updater image name.
For example, onie-firmware-x86_64-dellemc_<platform>_c2538-rx.x.xx.x.x-x.bin. Where <platform>
is the name of the switch and x.xx.x.x-x is the firmware version.
2. Copy the renamed image to the USB.
3. Insert the USB in the target system.
4. Boot the target system to ONIE Self-Update mode.
ONIE Discovery locates the image on the USB and starts the firmware update process.
