Hi Andrei
My question is that I set MB_P12V "upper critical" is 13.23, "upper non critical" is 12.6, etc .
When I login web page, I can see the setting what I want.
But when I use “Ipmitool sensor” command, the response is wrong. Like below
MB P12V | 7.215 | Volts | ok | na |6.386 | 6.723 | 7.429 | 7.829 | na
I am not sure am I miss something.
Thanks
Paul
