4. From the Configuration/Setup Utility menu, select Start Options.
5. From the Start Options menu, select Startup Sequence Options.
6. Note the device that is selected as the first startup device. Later, you must
restore this setting.
7. Select DVD-ROM as the first startup device.
8. Press Esc two times to return to the Configuration/Setup Utility menu.
9. Insert the IBM Enhanced Diagnostics CD in the CD drive.
10. Select Save & Exit Setup and follow the prompts. The diagnostics will load.
11. 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 RAID arrays not connected to the integrated SAS
controller.
v The server contains SATA or IDE hard disk drives not connected to the
integrated SAS controller.
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 140.
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 multiple error codes or light path diagnostics LEDs indicate a
microprocessor error, the error might be in a microprocessor or in a microprocessor
socket. See "Microprocessor problems" on page 123 for information about
diagnosing microprocessor problems.
If the server stops during testing and you cannot continue, restart the server and try
running 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 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. You can use the
regular keyboard test to test a USB keyboard, and you can use the regular mouse
test to test a USB mouse. You can run the USB interface test only if no USB
devices are attached. The USB test will not run if a Remote Supervisor Adapter II
SlimLine is installed.
To view server configuration information (such as system configuration, memory
contents, interrupt request (IRQ) use, direct memory access (DMA) use, device
drivers, and so on), select Hardware Info from the top of the screen.
