Diagnostic programs, messages, and error codes The diagnostic programs are the primary method of testing the major components of the server. As you run the diagnostic programs, text messages and error codes are displayed on the screen and are saved in the test log. A diagnostic text message or error code indicates that a problem has been detected; to determine what action you should take as a result of a message or error code, see the table in "Diagnostic error codes" on page 145. Running the diagnostic programs To run the diagnostic programs, complete the following steps: 1. If the server is running, turn off the server and all attached devices. 2. Turn on all attached devices; then, turn on the server. 3. When the prompt F2 for Diagnostics appears, press F2. If you have set both a power-on password and an administrator password, you must type the administrator password to run the diagnostic programs. 4. From the top of the screen, select either Extended or Basic. 5. From the diagnostic programs screen, select the test that you want to run, and follow the instructions on the screen. When you are diagnosing hard disk drives, select SCSI Attached Disk Test for the most thorough test. Select Fixed Disk Test for any of the following situations: v You want to run a faster test. v The server contains SATA or IDE hard disk drives. For help with the diagnostic programs, press F1. You also can press F1 from within a help screen to obtain online documentation from which you can select different categories. To exit from the help information, press Esc. To determine what action you should take as a result of a diagnostic text message or error code, see the table in "Diagnostic error codes" on page 145. If the diagnostic programs do not detect any hardware errors but the problem remains during normal server operations, a software error might be the cause. If you suspect a software problem, see the information that comes with your software. A single problem might cause more than one error message. When this happens, correct the cause of the first error message. The other error messages usually will not occur the next time you run the diagnostic programs. Exception: If there are multiple error codes or diagnostics LEDs that indicate a microprocessor error, the error might be in a microprocessor or in a microprocessor socket. See "Microprocessor problems" on page 131 for information about diagnosing microprocessor problems. If the server stops during testing and you cannot continue, restart the server and try to run the diagnostic programs again. If the problem remains, replace the component that was being tested when the server stopped. The keyboard and mouse (pointing device) tests assume that a keyboard and mouse are attached to the server. If no mouse or a USB mouse is attached to the server, you cannot use the Next Cat and Prev Cat buttons to select categories. All other mouse-selectable functions are available through function keys.
