System Event Log Messages for IPMI Systems 59
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.
<Sensor Name/Location>
voltage sensor detected a
warning <Reading>.
Warning Voltage of the monitored
entity
<Sensor Name/Location>
exceeded the warning
threshold.
<Sensor Name/Location>
voltage sensor returned to
normal <Reading>.
Information The voltage of a previously
reported
<Sensor Name/Location> is
returned to normal state.
Table 3-3. 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.
