11.6 BMC FW Health Sensor

The BMC tracks the health of each of its IPMI sensors and reports failures by providing a "BMC FW Health" sensor of the IPMI 2.0
sensor type Management Subsystem Health with support for the Sensor Failure offset. Only assertions will be logged into the SEL
for the Sensor Failure offset. The BMC Firmware Health sensor asserts for any sensor when 10 consecutive sensor errors are read.
These are not standard sensor events (that is, threshold crossings or discrete assertions). These are BMC Hardware Access Layer
2
(HAL) errors such as I C NAKs or internal errors while attempting to read a register. If a successful sensor read is completed, the
counter resets to zero.

11.6.1 BMC FW Health Sensor – Next Steps
1. Check the SEL for any other events around the time of the failure.
2. Take note of all IPMI activity that was occurring around the time of the failure. Capture a System BMC Debug Log as soon as you
can after experiencing this failure. This log can be captured from the Integrated BMC Web Console or by using the Intel
utility (syscfg /sbmcdl private filename.zip). Send the log file to your system manufacturer or Intel representative for failure
analysis.
3. If the failure continues around a specific sensor, replace the board with that sensor.
