Fan Sensor Events
The cooling device sensors monitor how well a fan is functioning. These messages provide status warning and failure messages for fans for a particular chassis.
Event Message | Severity | Cause |
<Sensor Name/Location> Fan sensor detected
a failure <Reading> where <Sensor Name/ Location> is the entity
that this sensor is monitoring. For example "BMC Back Fan" or "BMC
Front Fan." Reading is specified in RPM. For example, 100 RPM. | Critical | The speed of the specified <Sensor Name/Location> fan is not sufficient to provide enough cooling to the system. |
<Sensor Name/Location> Fan sensor returned
to normal state <Reading>. | Information | The fan specified by <Sensor Name/ Location> has returned to its normal operating speed. |
<Sensor Name/Location> Fan sensor detected
a warning <Reading>. | Warning | The speed of the specified <Sensor Name/Location> fan may not be sufficient to provide enough cooling to the system. |
<Sensor Name/Location> Fan Redundancy
sensor redundancy degraded. | Information | The fan specified by <Sensor Name/ Location> may have failed and hence, the redundancy has been degraded. |
<Sensor Name/Location> Fan Redundancy
sensor redundancy lost. | Critical | The fan specified by <Sensor Name/ Location> may have failed and hence, the redundancy that was degraded previously has been lost. |
<Sensor Name/Location> Fan Redundancy
sensor redundancy regained | Information | The fan specified by <Sensor Name/ Location> may have started functioning again and hence, the redundancy has been regained. |
Fan <number> RPM is less than the lower
warning threshold. | Warning | The speed of the specified fan might not provide enough cooling to the system. |
Fan <number> RPM is less than the lower
critical threshold. | Critical | The speed of the specified fan is not sufficient to provide enough cooling to the system. |
Fan <number> RPM is greater than the
upper warning threshold. | Warning | The speed of the specified fan exceeded the warning threshold. |
Fan <number> RPM is greater than the
upper critical threshold. | Critical | The speed of the specified fan exceeded the critical threshold. |
Fan <number> RPM is outside of range. | Critical | The speed of the specified fan might not provide enough cooling to the system. |
Fan <number> RPM is within range. | Information | The speed of the specified fan is operating in a normal range. |
Fan <number> is removed. | Critical | A required fan was removed. |
Fan <number> was inserted. | Information | A fan was added. |
Fan <number> is present. | Information | The total number of fans present. |
Fan <number> is absent. | Critical | A required fan is missing. |
The fans are redundant. | Information | One or more fans may have started functioning or installed and the redundancy has been regained. |
Fan redundancy is lost. | Critical | One or more required fans may have failed or removed and hence, the redundancy was lost. |
Fan redundancy is degraded. | Warning | One or more fans may have failed or removed and hence, the redundancy has been degraded. |
