Equivalent of "eeprom console=ttya" for Linux


Hi guys,

Trying to fix some ILO issues on a Sun server running SLes. Have tried lots of different things from the BIOS menu and the settings are not sticking.

Do you know if there is a Linux equivalent to the solaris command "eeprom console=ttya"?


regards,
Flukey

Have you tried appending "console=ttyS0" to your kernel boot options?

Thanks for reply. What exactly would that do? This is a pretty old important server so I don't want to mess anything up in the boot options. An equivalent command that I can run from the shell would be ideal.

You can specify multiple consoles in the kernel boot options, and the last one listed will be used as /dev/console. So, you could put console=ttyS0 console=tty0 and the console output would be duplicated on both the screen and the first serial port. I am not aware of any command that would be able to change the system console output to another device once the system is already booted.

I have experience with Sun equipment; perhaps if you told me the model of machine and what LOM issues you're having, I might be able to help you with that.

The vendor fixed the problem with this paticular system by replaceing the mother board so its not an issue anymore. The issue seems to be common enough with x4140 sun systems. The ILO settings don't seem to save (even after multiple boots). Since vendors do not look at systems without proof that there is something wrong in the logs, they wanted the output of the "eeprom console=ttya" command which is a solaris command.
It would still be handy to have a command that will display the same information that the eeprom command gives in case the issue comes up again.
