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.
