Troubleshoot Hardware Faults

This procedure provides an example of troubleshooting hardware faults.This procedure expands upon the basic steps described in Service Troubleshooting Task List.

Use this procedure to troubleshoot hardware faults with the Oracle ILOM web interface and, if necessary, prepare the server for service.

1. Review the server module Product Notes for information about the server, problem, or hardware.

   The Product Notes contains up-to-date information about the server, including hardware-related issues.

2. Access Oracle ILOM CMM.

   The CMM provides an overview of all chassis subsystems to help you isolate the fault.

   • Open a web browser.

   • Type in the CMM SP IP address.

   • At the log-in screen, enter a login with root or administrator privileges.

3. identify the chassis subsystem that requires service.

   View the ILOM Summary screen Status section, Status section of the Summary screen for information about the following chassis subsystems:

   • Blades

   • Power

   • Cooling

   • Storage

   • I/O Modules

   In the following example, the Status section indicates that service is required on one of the blades in the blades subsystem, and the Open Problems link in the left navigation panel shows one (1) logged problem:

   
   
4. View specific information by clicking Open Problems in the left navigation panel.

   The Open Problems screen provides detailed information about the issue, such as the time the event occurred, the component, the subsystem, and a description.

   In the following example, the Open Problems screen indicates that a problem has occurred on blade 2 (BL2):

   
   
5. View the System Log.

   The System Log provides additional detailed information about the error (event), including the severity, the component or subsystem, and the date and time the event occurred.

6. Access the server module Oracle ILOM.

   The server module Oracle ILOM provides specific information about the server module and its components.

   1. Access a web browser.
   2. Type in the server module SP IP address.
   3. At the log-in screen, enter a login with root or administrator privileges.
7. View the Summary screen Status section for service required and other error indications.

   Identify the component that is in a fault state from the server module Oracle ILOM web interface.

   The Status section provides information for the following subsystems:

   • Processors

   • Memory

   • Power

   • Cooling

   • Storage

   • Networking

   • I/O Modules

   In the following example, the server module Status section shows that the Memory subsystem requires service:

   
   
8. Click the Open Problems link in the left navigation panel.

   The Open Problems screen provides detailed information about the issue, such as the time the event occurred, the component, the subsystem, and a description.

   In the following example, the Open Problems screen indicates that DIMM 8 on CPU 0 has an uncorrectable ECC fault. In this example, the hardware fault with DIMM 8 of CPU 0 on blade 2 (BL2) requires local access to the server.

   
   
9. View the System Log.

   The System Log provides additional detailed information about the error (event), including the severity, the component or subsystem, and the date and time the event occurred.

10. Replace the failed component.
    1. To prepare the server for service, see Preparing the Server Module for Component Replacement.
    2. To service components, see Servicing Server Module Components .
    3. To return the server to service, see Returning the Server Module to Operation .
11. After servicing the component, you might need to clear the fault in Oracle ILOM.

    Refer the component service procedure for more information. See Servicing Server Module Components .
