Sensor state values during boot process
The key stages of operation.
Initial power on to BMC ready state
In this stage, some indicator values might not reflect the status of the physical sensor. In some
instances, the state is not available because the sensor is not initialized; in this case, the sensor
color is gray. In other cases (typically associated with Host Boot sensors), the value of the sensor
shows the state when the system was operational. These sensors update to indicate the current
status if the display is refreshed when the system reaches the Petitboot stage of operation. Table 3
shows the affected indicators.
BMC ready to PetitBoot or Host operation state
When the system reaches the Petitboot menu stage, and you refresh the display, all of the
indicators reflect their operational state.
