Supermicro IPMI Reporting

[ere109]

I had a random system failure last night, after five days of uptime. The system was still "running," but had lost the boot drive and crashed. The room was HOT, and I suspect I hit some temperature threshhold that shut something down - but I never got a report. So I went into IPMI to see my temps and stats before restarting. The problem is, IPMI couldn't report anything.

The log only showed my last bootup, and the "Sensor Readings" page gave no information at all. FreeNAS does a fine job of reporting CPU temperature, and the motherboard reports that there are RAM sensors, so I'm confused why my IPMI interface wouldn't be able to report. Is there a fix, or should I be worried about something?

Very interestingly, after my reboot, several sensors, fan temperatures and voltages showed up - they were ALL blank moments ago. So this was a board crash - to my knowledge. Would high heat do this, and is there a FreeNAS setting I can configure to shutdown if I reach a certain threshhold?

Thanks.

I actually had this happen once, where the IPMI sensors all showed "NOT PRESENT".

It was when I was just putting together a new system, and I was test booting it, without the auxiliary power connector being on. I never did determine if THAT was why they showed "not present". That was on an X11SSM.

Thanks. Very interesting. I've got the main 24-pin and the aux 8-pin power connectors hooked up. My power supply doesn't have a self-reporting port, though - not that that would affect reporting on the motherboard itself.
I'm fairly certain it was a heat issue. The temps here have been in the high 90's, and my office gets about six hours of sun and no A/C, so probably 45 degree celsius ambient air... It'll be great in th winter. Not sure what to do in the summer.
