Boot into ONIE
Issue
I already have Cumulus Linux running but I want to boot back into ONIE for troubleshooting/installation issues.
You use ONIE (the Open Network Install Environment) to install Cumulus Linux on open networking switches.
Environment
- Cumulus Linux, all versions
Resolution
Log in to your switch via the console.
Reboot the switch:
cumulus@switch~:# sudo reboot
Press any key when you see the following prompt:
Hit any key to stop autoboot: 0
ARM switches only: The switch now boots into U-Boot.
switch-> version U-Boot 2013.01.01-g1f891da (Sep 23 2013 - 18:31:29) ONIE 1.6.5 powerpc-linux-gcc (GCC) 4.7.2 GNU ld (GNU Binutils) 2.22 switch-> switch->
To boot into ONIE install mode, type the following commands:
-> setenv onie_boot_reason install -> run bootcmd
Install mode automatically starts trying to install a switch binary (like Cumulus Linux). If it keeps booting into Cumulus Linux and you just want to get to the ONIE prompt, use rescue mode instead:
-> setenv onie_boot_reason rescue -> run bootcmd
Select ONIE from the GRUB menu, then press Enter to access the ONIE console.
