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:

WARN - oracle_ibswitch:dm01sw-iba0.oracle.com:Sensors:AggregateSensors
oracle.sysman.emSDK.agent.fetchlet.exception.FetchletException: Can't get query descriptor or execution descriptor

WARN - oracle_ibswitch:dm01sw-iba0.oracle.com:Sensors:VoltageSensors

WARN - oracle_ibswitch:dm01sw-iba0.oracle.com:Sensors:TemperatureSensors

WARN - oracle_ibswitch:dm01sw-iba0..oracle.com:Sensors:FanSpeedSensors

 The switch name - dm01sw-iba0.oracle.com - will reflect your environment.
