Suppressing boot progress bar from LOM boot screen

Kaspars_Zibarts — Wed, 04 May 2022 19:34:58 GMT

I have lost my notes.. does anyone remember how to disable the progress bar when booting from LOM and seeing actual boot sequence log? Played with couple of GRUB parameters but still no joy

I‘m not sure, but normal Linux console switch should work Ctrl+Alt+Fn to change the displayed screen.

Thanks! Tried but didn't work 😞 will keep digging as I need to get boot sequence log from a remote node 😞

@Kaspars_Zibarts something to play this morning.... 8)

change "console=serial" to "console=CURRENT" in the needed line in /boot/grub/grub.conf

To get more messages remove the "quiet"

hope this helps

I was about to write it here haha Thanks! I did my own entry in grub boot list (/boot/grub/grub.conf)

BTW - interesting part with changing only "console=serial" to "console=CURRENT" was that I lost connectivity on regular serial port after boot.

So I think the options given in "debug on" mode are quite good to have both serial and terminal with keyboard

console=tty1 console=CURRENT kgdboc=kbd,ttyS0

Yes, that's correct with "console=CURRENT" only you'll loose both the RJ45 serial console and the USB serial console.

Thanks @Wolfgang really appreciated!

Next challenge with the LOM Java terminal is to copy text output.. 🙂 can record video of course but having plain text would be nice. Funny challenges when GW is too far away and all you have is LOM

@Wolfgang I was that close to squash the comment as a spam 🙂
