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.

Table 1. Fan Sensor Events
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.
