If the condition that caused the original assertion is no longer present at the time the re-arm
occurs, then the entire sequence is as follows:
1. Failure condition occurs and Integrated BMC logs an assertion event.
2. Sensor is re-armed.
3. Integrated BMC clears sensor status and generates a de-assertion event.
4. Sensor is put into “Init in progress” state until sensor is polled again or otherwise
updated.
5. Sensor is polled and the “Init in progress” state is cleared.
If the condition that caused the original assertion is present at the time the re-arm occurs, then
the entire sequence is as follows:
1. Failure condition occurs and Integrated BMC logs an assertion event.
2. Sensor is re-armed
3. Integrated BMC clears sensor status and generates a de-assertion event.
4. Sensor is put into “Init in progress” state until sensor is polled again or otherwise
updated.
5. Sensor is polled, the failure detected, and the Integrated BMC logs an assertion event.
All auto re-arm sensors that show an asserted event status generate a de-assertion SEL event
at the time the Integrated BMC detects that the condition causing the original assertion is no
longer present and the associated SDR is configured to enable a de-assertion event for that
condition.
4.16 Processor Sensors
The Integrated BMC provides IPMI sensors for processors and associated components, such as
voltage regulators and fans. Most of these sensors are implemented on a per-processor basis.
Table 25. Processor Sensors
Sensor Type Per-Proc Socket Description
Processor Status Yes Processor presence and fault state
Processor Temperature Yes Temperature from processor itself
Processor VRD Over-temperature
Indication
Yes Discrete sensor that indicates a processor VRD has
crossed an upper operating temperature threshold
Processor Voltage Yes Threshold sensor for voltage from processor voltage
regulator
Processor Voltage Limit Fault Yes Discrete sensor that indicates a processor voltage is out
of range
Processor Fan Speed Yes Speed of processor fan (not always present)
Processor Thermal Control (ProcHot) Yes Percentage of time a processor is throttling due to
thermal conditions
CPU Population Error No Improper socket population. This means slot 1 is empty.
4.16.1 Processor Status Sensors
The Integrated BMC provides an IPMI sensor of type ‘processor’ for monitoring status
information for each processor slot. With the exception of the processor presence offset, if an
