Troubleshooting the Server and Restoring ILOM Defaults |
This chapter introduces the diagnostic tools you can use to troubleshoot or monitor the performance of your server. It also includes information about how to restore the service processor (SP) password and serial connection defaults in Oracle Integrated Lights Out Manager (ILOM), as well as how to restore your ILOM SP firmware.
Note - Oracle integrated Lights Out Manager formerly was called Sun Integrated Lights Out Manager. |
The server and its accompanying software and firmware contain many diagnostic tools and features that can help you:
Oracle provides a suite of diagnostic tools, each of which has its own specific strengths and applications. For more information about which tool might be best to use for your purpose, and where to locate information about these tools, see:
Oracle provides a wide selection of diagnostic tools for use with your server. These tools range from the SunVTS software, a comprehensive validation test suite, to log files in ILOM that might contain clues helpful in identifying the possible sources of a problem, and the fault management function in ILOM that enables you to identify a faulted component as soon as the fault occurs.
The diagnostic tools range from standalone software packages, to firmware-based tests like power-on self-test (POST), U-Boot tests, or Pc-Check tests, to hardware LEDs that tell you when the system components are operating.
TABLE 7-1 summarizes the variety of diagnostic tools that you can use when troubleshooting or monitoring your server.
TABLE 7-2 identifies where you can find more information about Oracle diagnostic tools.

You can use the Preboot Menu utility installed on your server to make changes to some of the ILOM settings while ILOM is not currently running. The Preboot Menu also enables you to reset ILOM to its default settings, as well as restore the SP firmware image on your system.
For more information about how to use the Preboot Menu Utility, see these sections:
To access the Preboot Menu, you must reset the SP and interrupt the boot process. You can interrupt the ILOM boot process by either:
For details about the requirements for this local access method, see Prerequisites for Accessing the Preboot Menu.
For details about the requirements for this remote access method, see Prerequisites for Accessing the Preboot Menu.
Some Preboot Menu settings must be configured first, and until they are, you must use the Locate button method to access the Preboot Menu.
For detailed instructions for accessing the Preboot Menu from a local or remote connection, see the following sections:
Ensure that the applicable requirements are met prior to accessing the Preboot Menu from either a local or remote connection.
You must connect a terminal or computer running terminal emulation software to the server.
