6.1 Processor Status Sensor
The BMC provides an IPMI sensor of type processor for monitoring status information for each processor slot. If an event state
(sensor offset) has been asserted, it remains asserted until one of the following happens:
 A rearm Sensor Events command is executed for the processor status sensor.
 AC or DC power cycle, system reset, or system boot occurs.
CPU Presence status is not saved across A/C power cycles and therefore will not generate a deassertion after cycling AC power.
