Diagnostic Flowchart

The following diagnostics are available to troubleshoot faulty hardware. See Change POST Parameters for more information about each diagnostic in this chapter.

Table 35 Diagnostic Flowchart Actions 

Action No.
Diagnostic Action
Resulting Action
For more information
Check Power OK and AC Present LEDs on the server.
The Power OK LED is located on the front and rear of the chassis.

The AC Present LED is located on the rear of the server on each power supply.

If these LEDs are not on, check the power source and power connections to the server.

Run the Oracle ILOM show faulty command to check for faults.
The show faulty command displays the following kinds of faults:
  • Environmental faults

  • External I/O Expansion Unit faults

  • Predictive Self-Healing (PSH) detected faults

  • POST-detected faults

Faulty FRUs are identified in fault messages using the FRU name.

Note - If the Oracle ILOM show faulty output includes an error string such as Ext sensor or Ext FRU, it indicates a fault in the External I/O Expansion Unit.

Check the Oracle Solaris log files and Oracle ILOM system event log for fault information.
The Oracle Solaris log files and the Oracle ILOM system event log record system events, and provide information about faults.
  • Browse the Oracle ILOM system event log for major or critical events. Some problems are logged in the event log but not added to the show faulty list

  • If system messages indicate a faulty device, replace the FRU.

  • To obtain more diagnostic information, go to Action No. 4

Run Oracle VTS software.
Oracle VTS is an application you can run to exercise and diagnose FRUs. To run Oracle VTS, the server must be running the Oracle Solaris OS.
  • If Oracle VTS reports a faulty device, replace the FRU.

  • If Oracle VTS does not report a faulty device, go to Action No. 5.

POST performs basic tests of the server components and reports faulty FRUs.
Determine if the fault is an environmental or configuration fault.
Determine if the fault is an environmental fault or a configuration fault.

If the fault listed by the show faulty command displays a temperature or voltage fault, then the fault is an environmental fault. Environmental faults can be caused by faulty FRUs (power supply or fan), or by environmental conditions such as when computer room ambient temperature is too high, or the server airflow is blocked. When the environmental condition is corrected, the fault will automatically clear.

If the fault indicates that a fan or power supply is bad, you can perform a hot-swap of the FRU. You can also use the fault LEDs on the server to identify the faulty FRU (fans and power supplies).

If the FRU displayed by the show faulty command is /SYS, the fault is a configuration problem. /SYS indicates no faulty FRU has been diagnosed, but there is a problem with the system configuration.

Determine if the fault was detected in the External I/O Expansion Unit.
Problems detected in the External I/O Expansion Unit include the text string Ext FRU or Ext Sensor at the beginning of the fault description.
Determine if the fault was detected by PSH.
If the fault displayed included a uuid and sunw‐msg-‐id property, the fault was detected by the Predictive Self-Healing software.

If the fault is a PSH-detected fault, refer to the PSH Knowledge Article web site for additional information. The Knowledge Article for the fault is located at the following link:

where message-ID is the value of the sunw-msg-id property displayed by the show faulty command.

After the FRU is replaced, perform the procedure to clear PSH-detected faults.

Determine if the fault was detected by POST.
POST performs basic tests of the server components and reports faulty FRUs. When POST detects a faulty FRU, it logs the fault and if possible, takes the FRU offline. POST detected FRUs display the following text in the fault message:

Forced fail reason

In a POST fault message, reason is the name of the power-on routine that detected the failure.

Contact technical support.
The majority of hardware faults are detected by the server’s diagnostics. In rare cases a problem might require additional troubleshooting. If you are unable to determine the cause of the problem, contact your service representative for support.
