Diagnostics

Server problems can be caused by hardware, software, or a user error.
An example of a user error is pressing the wrong key on the keyboard.

The following tools are available to help identify and resolve hardware-related problems:

Diagnostic programs
Power-on self-test (POST)
POST beep codes
Error messages
Troubleshooting charts
System error log
Option diskettes

Diagnostic Programs: The server diagnostic programs are stored on electrically erasable programmable read-only memory (EEPROM).
These programs are the primary method of testing the major components of the server and some external devices.

Also, if you cannot determine 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 properly.

Note: When you run the diagnostic programs, a single problem might cause several error messages.
When this occurs, work to correct the cause of the first error message.
After the cause of the first error message is corrected, the other error messages might not occur the next time you run the test.

Power-On Self Test (POST): 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.

POST does the following:

Checks the operation of some basic I/O function card, processor board, and I/O board operations
Checks the memory
Compares the current server configuration with the stored server configuration information
Configures PCI adapters
Starts the video operation
Verifies that drives (such as the diskette, CD-ROM, and hard disk drives) are connected properly

If you have a power-on password or administrator password set, you must type the password and press Enter before POST will continue.

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 and an error message appears on the screen.

Note: A single problem might cause several error messages.
When this occurs, work to correct the cause of the first error message. After the cause of the first error message is corrected, the other error messages usually will not occur the next time you run the test.

POST Beep Codes: POST generates beep codes to indicate successful completion or the detection of a problem.

One beep indicates the successful completion of POST.
More than one beep indicates that POST detected a problem.
For more information, see 'Beep Symptoms'.

Error Messages: 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 indicated by error messages should be performed by trained service personnel.

Hardware error messages that occur can be text, numeric, or both.
Messages generated by the software generally are text messages, but they also can be numeric.

POST Error Messages: POST error messages occur during startup when POST finds a problem with the hardware or detects a change in the hardware configuration.
For a list of POST errors, see 'POST Error Codes'.

System Monitoring Messages: System monitoring messages occur as the Advanced Remote Management Controller monitors critical system functions.
For a list of codes, see 'System Management Codes'.

Diagnostic Error Messages: Diagnostic error messages occur when a test finds a problem with the server hardware.
These error messages are alphanumeric and they are saved in the Test Log.
For a list of diagnostic error codes, see 'Diagnostic Error Codes'.

Software-Generated Error Messages: These messages occur if a problem or conflict is found by an application program, the operating system, or both.
Messages are generally text messages, but they also can be numeric.
For information about these error messages, refer to the documentation that comes with the software.

System Error Log: The system error log contains all error and warning messages issued during POST and all system status messages from the Advanced Remote Management Controller (system management adapter).
See 'System Error Log' for information about how to view the system error log.

Option Diskettes: An optional device or adapter can come with an Option Diskette.
Option Diskettes usually contain option-specific diagnostic test programs or configuration files.
If the optional device or adapter comes with an Option Diskette, follow the instructions that come with the option. Different instructions apply depending on whether the Option Diskette is startable or not.
