When all your SuperMicro X9/X10/X11 IPMI sensors show N/A: the system is in a BIOS or boot selection screen
Posted by jpluimers on 2021/05/17
I have seen this happen on various Supermicro X9/X10/X11 systems including X9SRi-F/X9SRi-3F/X10SRH-CF/X11SPM-F boards:
I found this via:
- [WayBack] IPMI no sensor readings and already reset | iXsystems Community
- [WayBack] Supermicro X10 and X11 motherboard FAQ | iXsystems Community
All the sensors read N/A
First of all, make sure you’re not in the BIOS setup menu. IPMI monitoring of sensors isn’t available there.
If that is not the case, the procedures listed under “The CPU/PCH temperatures read N/A” may help.
The CPU/PCH temperatures read N/A
While the exact cause is unknown, the BMC may enter a faulty state, requiring a reset.
The following options were recommended to me by Supermicro:
- Start by power cycling the IPMI. This can be done from the web interface.
- If that doesn’t work, reset it to factory defaults via the web interface and power cycle it (it will not work until it is properly power cycled).
