Sensor status
You can check the sensor status to quickly determine the general health of the system without using the
event codes.
To view the sensor status, use the following command:
openbmctool -U <username> -P <password> -H <BMC IP address or BMC host name> fru status
To view the sensor status and any corresponding event codes, use the following command:
openbmctool -U <username> -P <password> -H <BMC IP address or BMC host name> fru status -v
Sensors that have a status of present and functional do not require a service action. Sensors that have a
status of present and not functional require a service action.
Some occurrences of errors in the system might not appear in the sensor status. After you view the sensor
status, look for event codes to determine whether a service action is required.
