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:
There are two types of CMM 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 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:
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”.
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:
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:
There are two network express module (NEM) slots available in the chassis. NEMs are numbered from 0 to 1.
These sensors report whether the NEMs are present.
These sensors report the state of any multi-fabric NEMs that are installed in the chassis.
These sensors report whether any multi-fabric NEMs have failed.
There are two power supply modules in the chassis. Each power supply module contains two power supplies or “sides” for the Sun Blade 6000 chassis and three power supply sides for the Sun Blade 6048 chassis. Power supply modules are numbered from 0 to 1 and power supply sides are numbered from 0 to 1.
Reports the presence of the power supply module.
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.

These threshold sensors report the ambient temperature of the power supply modules.
These threshold sensors report the power supply module 12V voltage reading.
These threshold sensors report the power supply module 3_3V voltage reading.
These threshold sensors report the power supply module 3_3V current rating.
Reports a power supply module 3_3V sensor fault.
This state indicates that a power supply 3_3V fault has not occurred. |
|||
This state indicates that a power supply 3_3V fault has occurred. |
Reports that ambient temperature reaches the following range: 50o to 60o C.
Reports presence of a power supply temperature error.
This state indicates that a power supply temperature fault has not occurred. |
|||
This state indicates that a power supply temperature fault has occurred. |
Reports presence of a power supply fan error.
This state indicates that a power supply fan fault has not occurred. |
|||
This state indicates that a power supply fan fault has occurred. |
These threshold sensors report the speed of the two fans in the power supply.
Reports the state of a power supply side.
This state indicates that a power supply side fault has not occurred. |
|||
This state indicates that a power supply side fault has occurred. |
These threshold sensors report the power supply side 12V voltage reading.
Reports a power supply side fault.
This state indicates that a power supply side fault has not occurred. |
|||
This state indicates that a power supply side fault has occurred. |
Reports a power supply side 12V voltage sensor fault.
Reports a power supply side 12V voltage sensor fault.
Reports that power supply side 12V output current exceeds 240A for 100 msec.
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.
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.
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.
These sensors report fan module failure status.
The Sun Blade 6000 chassis has 10 blade slots for server or storage modules (blade modules) and blade slots are numbered from 0 to 9.
The Sun Blade 6048 chassis has 12 blade slots for server or storage modules (blade modules) and blade slots are numbered from 0 to 11.
These sensors report whether server modules are present in the specified slots.
These sensors report the state of the server modules.
These sensors report whether there is a fault on the server module.
These sensors report the virtual power for the server modules. This sensor should match the /SYS/VPS sensor reading on the server module. Slots are numbered from 0 to 9 for Sun Blade 6000 and 0 to 11 for Sun Blade 6048.
This sensor is only available on some server modules, and only if the server module is running ILOM 3.0. Otherwise, BLn/VPS will report "no reading". Refer to the server module documentation to determine whether or not this sensor is available.
The following sensors are for the Sun Blade 6000 and Sun Blade 6048 chassis.
This sensor reports if any blade is requesting full fan speed due to high temperature.
This state indicates that no blade is requesting full fan speed. |
|||
This state indicates that one ore more blades is requesting full fan speed. |
T_AMB reports ambient air temperature based on available power supply inlet air temperature readings. This sensor is for monitoring only; no threshold is defined.
Reports power supply oversubscription state.
Power supplies are not oversubscribed; blade modules are allowed to turn on. |
|||
Power supplies are oversubscribed; some blade modules might not turn on. |
