ProLiant IPMI monitoring - Possible values of Megacell Status sensor

[Felipe-c]

I am monitoring ProLiant servers via IPMI (mostly DL360 and D380 gen9 and gen10).

A server with a good storage battery returns value 4 for the Megacell Status IPMI sensor. A server with a failed battery returns 6.

Where can I find all the possible values for the Megacell Battery Sensor so I can set proper triggers in my monitoring system? Or even better, where can I  find values for all the IPMI sensors?

Thanks,

Felipe.

The Megacell status is of type 0x29 Battery. Looking at the IPMI specs, we can find the defined values.

$ ipmitool -I lanplus -U someuser -H 10.10.10.1 -P somepassword sdr get "Megacell Status" -v
Running Get PICMG Properties my_addr 0x20, transit 0, target 0x20
Error response 0xc1 from Get PICMG Properities

As described on section 42 of the following document:

Type 0x29 (discrete) has the following bitmap:

0x00 - Battery Low / Predictive Failure

0x01 - Battery Failed

0x02 - Battery Presence Detected
