Using Oracle ILOM to Diagnose Hardware Faults
In rare cases, faults associated with uncorrectable CPU errors are not diagnosable or displayed in the controller. These faults are preserved by and observable on the Oracle Integrated Lights Out Manager (ILOM), which resides in the Service Processor (SP). Connect to Oracle ILOM to diagnose hardware faults that do not appear in the BUI.
Oracle ILOM provides options for network and serial port connectivity. Network connection is the preferred choice because the Oracle ILOM serial port does not always allow adequate means of platform data collection. Network connections are on port 215, and serial connections are on SSH port 22.
 | Caution - Failure to configure Oracle ILOM connectivity may lead to longer than necessary hardware fault diagnosis and resolution times. |
For information about using Oracle ILOM, refer to the Oracle Integrated Lights Out Manager (ILOM) Documentation Library at http://www.oracle.com/goto/ILOM/docs.
To identify the Oracle ILOM firmware version, and to log in to Oracle ILOM to view and clear CPU faults, use the following tasks:
