Fault Diagnosis Daemon Detects Unexpected Telemetry Error in Virtual Sensor (26360527)

If the server detects unexpected telemetry with a virtual sensor, the virtual sensor and /SYS will become faulted.

Use the Oracle ILOM show /System/Open_Problems command to display these faults.

In the show /System/Open_Problems output, virtual resource names end with the _VIRTUAL string. In the following example, /SYS/COOLINGZONE/DCU0/BOB/T_BOB_VIRTUAL is a virtual resource.

-> show /System/Open_Problems

Recovery: Use the fault management shell to clear the faults.

  1. Identify the UUIDs of the faulted virtual resources in the show /System/Open_Problems output.

    Virtual resources end with the _VIRTUAL string. In the preceding example, /SYS/COOLINGZONE/DCU0/BOB/T_BOB_VIRTUAL is a virtual resource and its UUID is ae862aca-8758-e6aa-d5bf-8896695fb551.

  2. Use the fault management shell to clear the faults.

    1. Start the fault management shell.

      -> start /SP/faultmgmt/shell
      Are you sure you want to start /SP/faultmgmt/shell (y/n)? y
    2. Use the fmadm faulty command to confirm the fault and UUID.

      Description : The fault diagnosis daemon (fdd) has detected unexpected
                    error telemetry and is unable to provide a diagnosis.
      
      Response    : Error reports describing the unexpected error telemetry have
                    been logged.
      
      Impact      : Automated diagnosis and response for these events will not
                    occur.
      
      Action      : Please refer to the associated reference document at
                    http://support.oracle.com/msg/ILOM-8000-56 for the latest
                    service procedures and policies regarding this diagnosis.
      
    3. Use the virtual resource's UUID to repair the fault.

      In this example, the UUID is ae862aca-8758-e6aa-d5bf-8896695fb551.

      After repairing the fault, exit the fault management shell.

      faultmgmtsp> fmadm repair ae862aca-8758-e6aa-d5bf-8896695fb551
      faultmgmtsp> exit
    4. Confirm that you faults have been repaired.

      -> show /System/Open_Problems
