Diagnostics
15
Notes:
a. If the server stops during testing and you cannot continue, restart the server
and try running the diagnostic programs again.
b. The keyboard and mouse (pointing device) tests assume that a keyboard and
mouse are attached to the server.
c. If you run the diagnostic programs with no mouse attached to the server, you
will not be able to navigate between test categories using the Next Cat and
Prev Cat
buttons. All other functions provided by mouse-selectable buttons
are also available using the function keys.
d. You can run the USB interface test and the USB external loopback test only if
there are no USB devices attached.
e. You can view server configuration information (such as system configuration,
memory contents, interrupt request (IRQ) use, direct memory access (DMA)
use, device drivers, and so on) by selecting Hardware Info from the top of the
screen.
When the tests have completed, you can view the Test Log by selecting Utility from
the top of the screen.
If the hardware checks out OK but the problem persists during normal server
operations, a software error might be the cause. If you suspect a software problem,
refer to the information that comes with the software package.
Viewing the test log
The test log will not contain any information until after the diagnostic program has
run.
Note: If you already are running the diagnostic programs, begin with step 3..
To view the test log:
1. Turn on the server and watch the screen.
If the server is on, shut down the operating system and restart the server.
2. When the message
F2 for Diagnostics
appears, press F2.
If a power-on password is set, the server prompts you for it. Type in the
appropriate password; then, press Enter.
3. When the Diagnostic Programs screen appears, select Utility from the top of the
screen.
4. Select View Test Log from the list that appears; then, follow the instructions on
the screen.
The system maintains the test-log data while the server is powered on. When you
turn off the power to the server, the test log is cleared.
Diagnostic error messages
For descriptions of the error messages that might appear when you run the diagnostic
programs, see “Diagnostic error codes” on page 115. If diagnostic error messages
appear that are not listed in those tables, make sure that the server has the latest levels
of BIOS, ServeRAID, and diagnostics microcode installed.
