Introduction to the Sun Blade Storage Module M2
Maintaining the Sun Blade Storage Module M2
There are two types of CMM sensors:
Discrete sensors display information about storage module components.
Threshold sensors show analog values, such as temperature readings or voltage levels.
Discrete sensors display a single value from a set of possible values.
Discrete sensors are displayed in the following format:
/PATH/TO/SENSOR Targets: $(POSSIBLE_SUB_SENSORS) Properties: type = $(SENSOR_TYPE) class = Discrete value = $(SENSOR_VALUE) alarm_status = $(SENSOR_STATUS)
Where the following variables are used:
POSSIBLE_SUB_SENSORS: A list of sensors below this sensor. Examples include fault or warning sensors. Using the cd command, you can navigate to the sub-sensor node.
SENSOR_TYPE: The type of sensor.
SENSOR_VALUE: The sensor value.
SENSOR_STATUS: The sensor alarm status (asserted, deasserted, cleared, severity).
The storage module manages the following environmental threshold sensors internally:
Voltage (3.3V, 1.8V, 12V, 1V)
Ambient and expander temperature
Total current draw
While these sensors are not viewable through the CMM ILOM, if any of them exceed the factory thresholds the storage module fault light will illuminate and an error will be reported in the CMM ILOM event log describing the slot with the fault. If the fault exceeds the critical level, the storage module will power off. You will then need to remove the storage module and correct the fault. Once the problem has been corrected, you can power on the storage module by reinserting it into the chassis.
