Sensors

This chapter contains ILOM sensor information for both the Sun Blade 6000 and Sun Blade 6048 chassis. The information in this section is specific for ILOM 3.0.

For sensor information for previous versions of ILOM, see the Integrated Lights Out Manager (ILOM) Administration Guide for the Sun Blade 6000 Modular System for Sun Blade 6000 and the Sun Blade 6048 Modular System Service Manual for the Sun Blade 6048.

This chapter contains the following sections:


Types of Sensors

There are two types of CMM sensors:

Discrete Sensors

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)

Where the following variables are used:

Threshold Sensors

Threshold sensors display analog readings, such as temperature or voltage levels, and can display associated thresholds for that reading. These can be configured to generate system events when they exceed specified thresholds.

In general, these sensors are displayed in the following format:


/PATH/TO/SENSOR
    Targets:
        $(POSSIBLE_SUB_SENSORS)
    Properties:
        type = $(SENSOR_TYPE)
        class = Threshold 
        value = $(SENSOR_VALUE) $(SENSOR_UNITS)
        upper_nonrecov_threshold = $(UNR_THRESH) $(SENSOR_UNITS)
        upper_critical_threshold = $(UC_THRESH) $(SENSOR_UNITS)
        upper_noncritical_threshold = $(UNC_THRESH) $(SENSOR_UNITS)
        lower_noncritical_threshold = $(LNC_THRESH) $(SENSOR_UNITS)
        lower_critical_threshold = $(LC_THRESH) $(SENSOR_UNITS)
        lower_nonrecov_threshold = $(LNR_THRESH) $(SENSOR_UNITS)

If the CLI has no access to threshold values, for example if a component is not present, the corresponding sensor is displayed as “0.000”.


Displaying Sensors

All sensors are located in the /CH namespace. To display the sensors using the CLI, separate the fields into targets and navigate using the cd and show commands.

For example, the speed for fan 0 in fan module 3 can be viewed by entering:

-> show /CH/FM3/F0/TACH



Note - If the chassis slot does not contain a server module, or if a power supply is not present, the corresponding target might not appear. For example, if slot 3 is empty, the target BL3 might not appear.



Sensor Information

All sensors listed in this section can be accessed through the ILOM CLI or web interface by placing /CH in front of the sensor path shown here. For example, to access the NEMn/PRSNT, use the path /CH/NEMn/PRSNT.



Note - The Reading value in column 1 of each table is used by impitool to represent the State shown in column 2.


The following sensors are described in this section:

NEM Sensors

There are two network express module (NEM) slots available in the chassis. NEMs are numbered from 0 to 1.

PSn/IN_POWER
These threshold sensors report the input (AC) power to the power supplies in Watts.

The power sensors are only accurate when the chassis is drawing a significant amount of power. Under low power conditions, the chassis cannot accurately measure power, so it will report "no reading". Typically, accurate power cannot be reported if the Sun Blade 6000 chassis is drawing less than 1500 Watts or if the Sun Blade 6048 chassis is drawing less than 2200 Watts.

PSn/OUT_POWER
These threshold sensors report the output (DC) power from the power supplies in Watts.

The power sensors are only accurate when the chassis is drawing a significant amount of power. Under low power conditions, the chassis cannot accurately measure power, so it will report "no reading". Typically, accurate power cannot be reported if the Sun Blade 6000 chassis is drawing less than 1500 Watts or if the Sun Blade 6048 chassis is drawing less than 2200 Watts.

VPS

VPS is the virtual power sensors and reports the total power used by the chassis (typically the sum of PS0/IN_POWER and PS1/IN_POWER).

The power sensors are only accurate when the chassis is drawing a significant amount of power. Under low power conditions, the chassis cannot accurately measure power, so it will report "no reading". Typically, accurate power cannot be reported if the Sun Blade 6000 chassis is drawing less than 1500 Watts or if the Sun Blade 6048 chassis is drawing less than 2200 Watts.

Fan Sensors

The Sun Blade 6000 chassis contains six fan modules and the Sun Blade 6048 chassis contains eight fan modules. Each module contains two fans. Fan modules are numbered from 0 to 5 for Sun Blade 6000 and 0 to 7 for Sun Blade 6048. Fans are numbered from 0 to 1.

FMn/Fn/TACH

These sensors report individual fan speeds. All fan speed sensors are configured to generate the same events and all faults are handled in the same way. They are not monitored when the chassis is powered off.
