Using the diagnostic diskette
Do the following to start the IBM Enhanced Diagnostics using the diagnostics
diskette, do the following:
1. Turn off your server and any peripheral devices.
2. Insert the IBM Enhanced Diagnostics diskette into the diskette drive.
3. Turn on all attached devices; then, turn on the server.
4. Follow the instructions on the screen.
5. Place the IBM Enhanced Diagnostics CD in the CD-ROM drive. The diagnostics will
load. Follow the instructions on the screen to run the diagnostics.
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 records data about system failures and other pertinent information. 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 4.
1. Insert the IBM Enhanced Diagnostics CD.
2. Turn on the system and watch the screen.
If the system is on, shut down your operating system and restart the system.
3. If a power-on password is set, the system prompts you for it. Type in the
appropriate password; then, press Enter.
4. Run the appropriate diagnostics program and when the Diagnostic Programs
screen appears, select Utility.
5. Select View Test Log from the list that appears; then, follow the instructions on
the screen.
6. You can save the test log to a file on a diskette or to your hard disk drive.
Note: The system maintains the test-log data while the system is powered on.
When you turn off the power to the server, the test log is cleared.
Diagnostic error message tables
For descriptions of the error messages that might appear when you run the diagnostic
programs, see “Diagnostic error codes” on page 89. If diagnostic error messages
appear that are not listed in those tables, make sure that the server has the latest levels
of BIOS, Advanced System Management Processor, ServeRAID, and diagnostics
microcode installed.
Power checkout
Power problems can be difficult to troubleshoot. For instance, a short circuit can exist
anywhere on any of the power distribution busses. Usually a short circuit will cause
the power subsystem to shut down because of an overcurrent condition.
A general procedure for troubleshooting power problems is as follows:
