Booting in ONIE Mode
Booting in ONIE Install Mode
© Copyright Lenovo 2017
After you activate ONIE, you can boot the switch in ONIE mode. ONIE offers four
modes for booting, each providing a different operation:
ONIE install mode
ONIE rescue mode
ONIE uninstall mode
ONIE update mode
There are three ways to boot the switch in an ONIE mode:
using the Command Line Interface (CLI):
Lenovo Cloud Network OS:
– startup image onie-image install
– startup image onie-image rescue
– startup image onie-image uninstall
– startup image onie-image update
using the Grub Menu that appears during startup (for more details, see
Grub Menu" on page
using the BIOS Menu (for more details, see
Note: For the NE2572, the CLI commands for booting in different ONIE modes
display an error if secure boot is not disabled on the switch. To disable secure boot,
see
"ONIE Activation" on page
The following pages describe the four ONIE modes and how the CLI commands
can be used to boot the switch in each mode.
This mode is used to install a NOS using ONIE. The ONIE install mode boots the
ONIE kernel and file-system and executes the ONIE discovery process. The
discovery process uses a number of different mechanisms to find a NOS installer
program.
Once a NOS installer is found, it is downloaded and executed. The installer loads
the Network OS on the switch, updates required ONIE environment variables, and
reboots the switch.
The switch now runs its newly installed Network OS and behaves like a regular
switch. The user can, at any point, reboot and run the ONIE installer again to
install another Network OS.
The Lenovo ONIE installer image, which installs the different Lenovo Network
Operating Systems, is called onie-installer-x86_64-lenovo_ne2572-r0,
