IY46601: UESENSOR SHOWS NO ENVIRONMENTAL SENSORS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Executing /usr/lpp/diagnostics/bin/uesensor -l returns the
  message "There are no environmental sensors on this system."
  However, the system may or may not have environmental sensors.
  
  In some cases, firmware chooses not to expose the
  environmental sensors to the operating system.  Of course, if
  any of the environmental sensors indicated a value out of
  normal operating range, then an error would get reported to
  the operating system and AIX diagnostics would analyze and
  report the error.
  

Local fix

• Executing /usr/lpp/diagnostics/bin/uesensor -l returns the
  message "There are no environmental sensors on this system."

Problem summary

  report the error.
  

Problem conclusion

• Change /usr/lpp/diagnostics/bin/uesensor in
  devices.chrp.base.diag to output the message "This function
  is not supported on this system." whenever firmware is not
  exposing any environmental sensors to the operating system.
