Booting in ONIE Update Mode
Booting in ONIE Rescue Mode
© Copyright Lenovo 2017
ONIE update mode will install a new version of ONIE on the switch, including the
boot loader and the Linux kernel. It works similarly to the ONIE install mode,
except the discovery process will search for an ONIE image instead, and not a NOS
image.
Notes:
This will only upgrade the ONIE partition on the switch and will not affect the
NOS image. ONIE installer images that can be used with ONIE Update mode
are available at the following link:
https://github.com/lenovo/networking-onie/
The installer image is called onie-updater-powerpc-lenovo_g8272-r0.
This will also install a different version of the ONIE boot loader, which does not
support running Lenovo Network OS. If you wish to boot Lenovo NOS, you will
have to re-install it by using ONIE Install mode (for more details, see
ONIE Install Mode" on page
To boot the switch in ONIE update mode on the next reload, use the following
command from the switch CLI:
Lenovo Enterprise Network OS:
G8272(config)# boot image onie-image update
Lenovo Cloud Network OS:
G8272(config)# startup image onie-image update
Note: Upon reloading after the update process is completed, the switch will not be
able to load the Lenovo Network OS, booting into ONIE Install mode instead.
ONIE rescue and recovery mode is useful when trying to recover from a broken
NOS image. It works similarly to the ONIE install mode, except the ONIE
discovery process is disabled. ONIE will not try to find and install a NOS image.
This allows for the troubleshooting of the system.
To boot the switch in ONIE rescue mode on the next reload, use the following
command from the switch CLI:
Lenovo Enterprise Network OS:
G8272(config)# boot image onie-image rescue
Lenovo Cloud Network OS:
G8272(config)# startup image onie-image rescue
