Hot-swap hard disk drive activity LED (some models)
On SCSI hot-swap server models, each hot-swap drive has a hard disk
drive activity LED. When this green LED is flashing, it indicates that the
drive is in use.
Hot-swap hard disk drive status LED (some models)
On SCSI hot-swap server models, each hot-swap hard disk drive has an
amber status LED. If the status LED for a drive is lit continuously, it
indicates that the individual drive is faulty. The interpretation of a flashing
status LED depends on the SCSI controller that is connected to the
hot-swap drive, as follows:
When the drive is connected to an optional ServeRAID™ adapter, a slowly
flashing (one flash per second) status LED indicates that the drive is being
rebuilt. When the LED is flashing rapidly (three flashes per second), it
indicates that the controller on the adapter is identifying the drive.
Ethernet transmit/receive activity LED
This LED is on the Ethernet connector. When this LED is lit, it indicates that
there is activity between the server and the network.

Chapter 3. Diagnostics
This chapter provides basic troubleshooting information to help solve some common
problems that might occur with the server.
If you cannot locate and correct the problem using the information in this section,
see Appendix A, “Getting help and technical assistance,” on page 141 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 143.
v The server diagnostic programs are stored on the IBM Enhanced Diagnostics
CD. These programs provide the primary methods of testing the major
components of the server. 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
server 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.
Important:
v
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 99.
4. If the server is suspended and no error message is displayed, see “Error
symptoms” on page 109 and “Undetermined problems” on page 127.
5. For information about power-supply problems, see “Power checkout” on page
21.
6. For intermittent problems, check the error log; see “Diagnostic programs,
error codes, and messages” on page 14.
© Copyright IBM Corp. 2004 11
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 99.
7. Check the system-error log.
Note: The system-error log is available only with the Remote
Supervisor Adapter II.
If an error was recorded by the server, see Chapter 6,
“Symptom-to-FRU index,” on page 97.
8. Start the diagnostic programs.
9. Check for the following responses:
v One beep
v Readable instructions or the main menu
DID YOU RECEIVE BOTH OF THE CORRECT RESPONSES?
003
NO. Find the failure symptom in Chapter 6, “Symptom-to-FRU index,” on
page 97.
YES. Run the diagnostic programs (see “Diagnostic programs, error codes,
and messages” on page 14).
If you receive an error, see Chapter 6, “Symptom-to-FRU index,” on page
97.
If the diagnostic programs were completed successfully and you still
suspect a problem, see “Undetermined problems” on page 127.
12 xSeries 226 Type 8488 and 8648: Hardware Maintenance Manual and Troubleshooting Guide
Diagnostic tools overview
The following tools are available to help you diagnose and solve hardware-related
problems:
v POST error logs
The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the detection of a problem.
The POST error log contains the three most recent error codes and messages
that the server has generated during POST.
The system-error log contains all the error messages that were issued during
POST.
Note: The system-error log is available only with the Remote Supervisor Adapter
II.
See “POST error logs” for more information.
v Diagnostic programs and error messages
The server diagnostic programs are the primary method of testing the major
components of the server (see “Diagnostic programs, error codes, and
messages” on page 14).
v System board error LEDs
These LEDs can help to pinpoint the source of a hardware problem (see “System
board error LEDs” on page 17).
v Ethernet controller troubleshooting
This section provides information about Ethernet problems (see “Troubleshooting
the Ethernet controller” on page 21).
POST error logs
When you turn on the server, it performs a series of tests to check the operation of
server components and some of the options installed in the server. This series of
tests is called the power-on self-test, or POST.
If POST finishes without detecting any problems, a single beep sounds, and the first
screen of the operating system or application program appears.
If POST detects a problem, more than one beep sounds, an error message appears
on the screen, or both (see “Beep symptoms” on page 97 and “POST error codes”
on page 99).
Note: A single problem might cause several error messages. When this occurs,
work 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 not
occur the next time you run the test.
The POST error log contains the three most recent error codes and messages that
the system generated during POST.
The system-error log contains all messages that were issued during POST and all
system status messages from the service processor.
Note: The system-error log is available only with the Remote Supervisor Adapter II.
Chapter 3. Diagnostics 13
You can view the contents of the system-error log from the Configuration/Setup
Utility program or from the diagnostic programs.
Viewing error logs from the Configuration/Setup Utility program
Start the Configuration/Setup Utility program; then, select Error Logs from the main
menu (see “Starting the Configuration/Setup Utility program” on page 10).
Viewing error logs from diagnostic programs
To view error logs from the diagnostic programs, complete the following steps:
1. Start the diagnostic programs (see “Starting the diagnostic programs” on page
15.
2. Select Hardware Info from the top of the diagnostic programs screen.
3. Select System Error Log from the list that appears; then, follow the instructions
on the screen.
Note: The system-error log is available only with the Remote Supervisor
Adapter II.
Diagnostic programs, error codes, and messages
The server diagnostic programs are stored on the IBM Enhanced Diagnostics CD.
These programs are the primary method of testing the major components of the
server.
Diagnostic error messages indicate that a problem exists. They are not intended to
be used to identify a failing part. Troubleshooting and servicing of complex
problems that are indicated by error messages should be performed by trained
service personnel.
Sometimes the first error to occur causes additional errors. In this case, the server
displays more than one error message. Always follow the suggested action
instructions for the first error message that appears.
Error codes that might be displayed are listed at “Diagnostic error codes” on page
104.
Notes:
1. Depending on the server configuration, some of the error codes might not
appear when you run the diagnostic programs.
2. If diagnostic error codes appear that are not listed in the tables, make sure that
the server has the latest levels of BIOS, Remote Supervisor Adapter II, and
ServeRAID code installed.
