Reporting Diagnostic Failures at System Startup

After U-Boot completes the diagnostic test, the test output and a final status of the U-Boot test appears on your screen. If a hardware failure is detected by U-Boot, the failure is reported in the test output. To view samples of the U-Boot test outputs, see Sample U-Boot Test Output.

Note - For troubleshooting purposes, a -Failed or -Passed status of the last U-Boot test performed on the server is also stored in the SP environmental variables. To view a sample output of the environmental variables showing the status of the U-Boot test, see Example 4.

When troubleshooting your system, note that the symptoms of a diagnostic failure can vary depending on whether the diagnostics at startup have failed on the server SP or host. For additional details about how to determine where the diagnostics failed at startup and possibly locate additional information about the failure, see the following table.

Component

Failure Status and Symptoms

Server SP

(U-Boot)

When the component failure is detected on the server SP, the failure is typically reported in the following locations:
– U-Boot test results
For sample output of U-Boot test results, see Sample U-Boot Test Output .
– ILOM event log.
For details about how to access this log, refer to the information about the ILOM event log in the Oracle Integrated Lights Out Manager 3.0 User’s Guide.
– Fault Management tab in the ILOM web interface
For more details about access and use of fault management, refer to the information about ILOM fault management in the Oracle Integrated Lights Out Manager 3.0 User’s Guide. To determine which faults you must manually clear on your server, refer to the platform ILOM Supplement Guide for your server.
If a component failed to start, the Service Action Required LED on the front panel of the server illuminates.
If the U-Boot diagnostic test failed, the server SP will not start.

Server Host (BIOS POST)

When the component failure is detected on the server host, the failure is typically reported in the following locations:
– Fault Management tab in the ILOM web interface
For more details about access and use of fault management, refer to the information about ILOM fault management in the Oracle Integrated Lights Out Manager 3.0 User’s Guide. To determine which faults you must manually clear on your server, refer to the platform ILOM Supplement Guide for your server.
– ILOM event log.
For details about how to access this log, refer to the information about the ILOM event log in the Oracle Integrated Lights Out Manager 3.0 User’s Guide.
If a component failed at startup, the Service Action Required LED on the front panel of the server illuminates.
If the BIOS POST detected a fatal error, the host operating system will not start.
