Error logs An overall status message will then appear. Partition merge successful If the merge was not successful, the message will indicate the failure (see "Verifying scalability and RXE cabling" on page 72). For example: Partition merge failed: No secondary SMP Exp. Modules merged The message above indicates that the secondary chassis was not seen. Partition mismatch: Expected partition 8-8, Actual partition 8-4 The message above indicates that one of the SMP Expansion Modules was not enabled. The POST error log contains the three most recent error codes and messages that the system generated during POST. The System Error log contains all messages issued during POST and all system status messages from the service processor. You can view the contents of the System Error log from the Configuration/Setup Utility program or from the diagnostic programs. Note: When troubleshooting problems with PCI-X slots, you will notice that the error logs report the PCI-X buses numerically. The numerical assignment will change depending on your configuration. Viewing error logs from the Configuration/Setup Utility program Start the Configuration/Setup Utility program; then, select Error Logs from the main menu. See "Using the Configuration/Setup Utility program" on page 14 for more information. Viewing error logs from the diagnostic programs Start the diagnostic programs; select Hardware Info from the top of the diagnostic programs screen; select System Error Log from the list that appears; then, follow the instructions on the screen. See "Starting the diagnostic programs" on page 70 for more information for more information. Light path diagnostics The server's light path diagnostics feature provides a path that can be followed in four phases to help identify the source of an error. The lights are designed to be followed in an orderly progression, depending on the error. The lights are viewed in the following order: 1. Begin on the front panel (see "Server controls and indicators" on page 4). 2. Proceed to the light path diagnostics panel (see Figure 27 on page 66). 3. Check the lights on the top of the server (see Figure 28 on page 67). 4. Look inside the server, if required. Many errors are first indicated by the illumination of the system-error light in the operator information panel on the front of the server (see "Server controls and indicators" on page 4). If the system-error light is on, one or more lights on top of and/or inside the server might also be on that can direct you to the source of the error. This section will describe how to follow this light path. Chapter 3. Diagnostics 65
