Chapter 3. Diagnostics

This chapter provides basic troubleshooting information to help solve some common problems that might occur with the computer.

If you cannot locate and correct the problem using the information in this section, see Appendix A, “Getting help and technical assistance,” on page 125 for more information.

General checkout

Follow the checkout procedure for diagnosing hardware problems. Review the following information before performing the checkout procedure:

v Read Appendix B, “Safety information,” on page 127. v The computer diagnostic programs are stored on the IBM Enhanced Diagnostics

CD. These programs provide the primary methods of testing the major components of the computer. If you are not sure whether a problem is caused by the hardware or by the software, you can run the diagnostic programs to confirm that the hardware is working correctly.

v When you run the diagnostic programs, a single problem might cause several

error messages. If you receive several error messages, correct the cause of the first error message. The other error messages might not occur the next time you run the diagnostic programs.

v Before running the diagnostic programs, you must determine whether the failing

computer is part of a shared hard disk drive cluster (two or more servers sharing external storage devices). If you suspect that it is part of a cluster, you can run all diagnostic programs except the ones that test the storage unit (that is, a hard disk drive in the storage unit) or the storage adapter that is attached to the storage unit. The failing server might be part of a cluster if any of the following conditions is true:

– The customer identifies the failing server as part of a cluster. – One or more external storage units are attached to the failing server and at

least one of the attached storage units is also attached to another server or unidentifiable device.

– One or more servers are located near the failing server.

v Important:

1. For servers that are part of a shared hard disk drive cluster, run one test at a time. Do not run any suite of tests, such as “quick” or “normal” tests, because this could enable the hard disk drive diagnostic tests.

2. If more than one error code is displayed, correct the first error. The other error codes might not occur the next time you run the diagnostic programs.

3. If the server is suspended and a POST error code is displayed, see “POST error codes” on page 85.

4. If the server is suspended and no error message is displayed, see “Error symptoms” on page 95 and “Undetermined problems” on page 113.

5. For information about power-supply problems, see “Power checkout” on page

22.

6. For intermittent problems, check the error log; see “Diagnostic programs and error messages” on page 16.

Complete the following steps to perform the checkout procedure:

001 IS THE SERVER PART OF A CLUSTER?

YES. Schedule maintenance for the system. Shut down all systems related

to the cluster. Run the storage test.

NO. Go to step 002.

002 IF THE SERVER IS NOT PART OF A CLUSTER:

1. Turn off the server and all external devices.

2. Check all cables and power cords.

3. Set all display controls to the middle position.

4. Turn on all external devices.

5. Turn on the server.

6. Record any POST error messages that are displayed on the screen. If an error is displayed, look up the first error in the “POST error codes” on page 85.

v Diagnostic programs

The system diagnostic programs are on a hidden partition on the hard disk. These programs are the primary methods of testing the major components of your computer. See “Diagnostic programs and error messages” on page 16 for more information.

v Symptom-to-FRU index

This index problem symptoms and steps to correct each problem. See the Chapter 6, “Symptom-to-FRU index,” on page 83 for more information.

v System-board error LEDs

An LED on the system board might also be lit to help isolate an error indicated by the system error LED on the front of the computer. See “System board error LEDs” on page 74 for more information.

Power-on self-test (POST)

When you turn on the computer, the power-on self-test (POST) performs a series of tests to check the operation of system components and some of the installed options.

If POST finishes without detecting any problems, the first window of your operating system or application program opens.

If POST detects a problem, more than one beep sounds and an error message appears on the screen.

Notes:

1. If you have set a user password, you must type the password and press Enter,

2. A single problem might cause several error messages. When this occurs, work

POST beep codes

Use the following beep code descriptions to help diagnose and solve problems that are detected during startup:

No beeps

Continuous beep

Beep codes for specific failures

when prompted, before the operating system will start.

to correct the cause of the first error message. After you correct the cause of the first error message, the other error messages usually will be resolved the next time you run the test.

If no beep occurs after the computer completes POST, see Chapter 6, “Symptom-to-FRU index,” on page 83.

The startup (boot) microprocessor has failed, or the system board or speaker subsystem might contain a failing component. If the computer continues through POST with no errors, got to “General checkout” on page 13 and run the diagnostic programs. If no video appears, the startup processor has failed.

Beep codes indicating specific system problems. For a list of beep codes, see “Beep symptoms” on page 83.

Chapter 3. Diagnostics 15

POST error messages

POST error messages can appear when a problem is detected during startup. For a complete list of POST messages, see “POST error codes” on page 85.

Diagnostic programs and error messages

Note: When using diagnostics with a USB keyboard and mouse attached, you

must first enable USB emulation. Complete the following steps to enable USB emulation:

1. Restart the computer and press F1 to start the Configuration/Setup Utility.

2. Select Devices and I/O Ports.

3. Select USB Setup.

4. Make sure that the USB keyboard and mouse are enabled.

Diagnostic error messages indicate that there is a problem; they are not intended to be used to identify a failing part. Troubleshooting and servicing complex problems that are indicated by error messages must be performed by trained service personnel.

Sometimes the first error to occur causes additional errors. In this case, the computer displays more than one error message. Always follow the suggested action instructions for the first error message that appears.

Text messages

The diagnostic text message format is as follows:

result test_specific_string

where:

result is one of the following results:

Passed

This test was completed without any errors.

Failed This test discovered an error. User Aborted

You stopped the test before it was completed.

Not Applicable

You attempted to test a device that is not present in the computer.

Aborted

The test could not proceed because of the computer configuration.

Warning

A possible problem was reported during the test (for example, a device that was to be tested is not installed).

test_specific_string

is an error code or other information about the error.

Starting the diagnostic programs and viewing the test log

The IBM Enhanced Diagnostics programs isolate problems from the computer hardware and software. The programs run independently of the operating system. This method of testing is generally used when other methods are not accessible or have not been successful in isolating a problem suspected to be hardware related.

Complete the following steps to view the test log.

Note: If you are already running the Enhanced Diagnostics program, begin with

step 4.

1. Start the Enhanced Diagnostics programs. v To start the Enhanced Diagnostics programs in a Windows operating system,

complete the following steps: a. Restart the computer and when the message To start the Product

Recovery program is displayed, quickly press F11.

b. Select System utilities. c. Select Run diagnostics to start the diagnostics programs.

v To start the Enhanced Diagnostics programs in Red Hat Linux operating

system, complete the following steps: a. Restart the computer. b. When the operating system selection menu is displayed, select IBM

Preload Recovery & Diagnostics.

c. Select Run diagnostics to start the diagnostics programs.

(Optionally, insert the IBM Enhanced Diagnostics diskette and restart the computer.)

2. Run the applicable diagnostics program and when the Diagnostic Programs screen appears, select Utility.

3. Select View Test Log from the list; then, follow the instructions on the screen. 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.

4. Save the test log to a file on a diskette or to your hard disk.

Notes:

a. To save the test log to a diskette, you must use a diskette that you have

formatted yourself; this function does not work with preformatted diskettes. If the diskette has sufficient space for the test log, the diskette can contain other data.

b. The system maintains the test-log data only while the Enhanced Diagnostics

program is running. When you end the Enhanced Diagnostics program, the test log is cleared.

For a complete list of diagnostic error messages, see “Diagnostic error codes” on page 90.

Small computer system interface (SCSI) messages

If you receive a SCSI error message when running the SCSISelect Utility program, it might be the result of any of the following problems:

v A failing SCSI device (adapter or drive) v An incorrect SCSI configuration

Chapter 3. Diagnostics 17

v Duplicate SCSI IDs in the same SCSI chain v An incorrectly installed SCSI terminator v A defective SCSI terminator v An incorrectly installed cable v A defective cable

To solve the problem, make sure that: v The external SCSI devices are turned on. External SCSI devices must be turned

on before the computer.

v The cables for all external SCSI devices are connected correctly. v The last device in each SCSI chain is terminated correctly. v The SCSI devices are configured correctly.

If the problem remains, run the diagnostic programs to obtain additional information about the failing device.

Note: If the computer does not have a SCSI hard disk drive, ignore any message

that indicates that the BIOS code is not installed.
