As well the the 'FanSpeedSensors' metric the following other sensor metrics are known to see this as well:
AggregateSensors
VoltageSensors
TemperatureSensors
Symptoms
You will see warning messages for the ibswitch in the Enterprise Manager under Monitoring ==>> Metrics Issues you will see the Oracle Infiniband Switch reporting errors on the Metrics for:
FanSpeedSensors
AggregateSensors
VoltageSensors
TemperatureSensors
If you check the gcagent.log, usually under <AGENT_INST>/sysman/log directory, you will see messages as follows in the agent log gcagent.log:
