Display system environmental sensors (CHRP)

Edit online
This Service Aid displays the environmental sensors implemented on a CHRP system. The information displayed is the sensor name, physical location code, literal value of the sensor status, and the literal value of the sensor reading.
Note: Runs on CHRP systems units only.

The sensor status can be any one of the following:

  • Normal

    The sensor reading is within the normal operating range.

  • Critical High

    The sensor reading indicates a serious problem with the device. Run diagnostics on sysplanar0 to determine what repair action is needed.

  • Critical Low

    The sensor reading indicates a serious problem with the device. Run diagnostics on sysplanar0 to determine what repair action is needed.

  • Warning High

    The sensor reading indicates a problem with the device. This could become a critical problem if action is not taken. Run diagnostics on sysplanar0 to determine what repair action is needed.

  • Warning Low

    The sensor reading indicates a problem with the device. This could become a critical problem if action is not taken. Run diagnostics on sysplanar0 to determine what repair action is needed.

  • Hardware Error

    The sensor could not be read because of a hardware error. Run diagnostics on sysplanar0 in problem determination mode to determine what repair action is needed.

  • Hardware Busy

    The system has repeatedly returned a busy indication, and a reading is not available. Try the Service Aid again. If the problem continues, run diagnostics, on sysplanar0 in problem determination mode to determine what repair action is needed.

This Service Aid can also be run as a command. The command can be used to list the sensors and their values in a text format, list the sensors and their values in numerical format, or a specific sensor can be queried to return either the sensor status or sensor value.

The command can be run by entering one of the following: 

/usr/lpp/diagnostics/bin/uesensor -l | -a
/usr/lpp/diagnostics/bin/uesensor -t token -i index [-v]
Flags
Item Description
-l List the sensors and their values in a text format.
-a List the sensors and their values in a numerical format. For each sensor, the following numerical values are displayed as: 

<token> <index> <status> <measured value> <location code>
-t token Specifies the sensor token to query.
-i index Specifies the sensor index to query.
-v Indicates to return the sensor measured value. The sensor status is returned by default.
Examples
  1. Display a list of the environmental sensors: 
    
/usr/lpp/diagnostics/bin/uesensor -l

    
Sensor Token = Fan Speed
Status = Normal
Value = 2436 RPM
Location Code = F1

Sensor Token = Power Supply
Status = Normal
Value = Present and operational
Location Code = V1

Sensor Token = Power Supply
*Status = Critical low
Value = Present and not operational
Location Code = V2
  2. Display a list of the environmental sensors in a numerical list: 
    
/usr/lpp/diagnostics/bin/uesensor -a

    
3 0 11 87 P1
9001 0 11 2345 F1
9004 0 11 2 V1
9004 1 9 2 V2
  3. Return the status of sensor 9004, index 1: 
    
/usr/lpp/diagnostics/bin/uesensor -t 9004 -i 1

9
  4. Return the value of sensor 9004, index 1: 
    
/usr/lpp/diagnostics/bin/uesensor -t 9004 -i 1 -v
