Chapter 3. Diagnostics

This section provides basic troubleshooting information to help you solve some common problems that might occur with the blade server.

If you cannot locate and correct the problem using the information in this chapter, see Appendix A, “Getting help and technical assistance,” on page 107 for more information.

Checkout procedure

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

vRead the safety information beginning on page 109.

vThe IBM Enhanced Diagnostics programs test the major components of the blade server: the processor board, the input/output (I/O) board, Ethernet controller, video controller, RAM, keyboard, mouse (pointing device), serial ports, and hard disk drives. You can also use them to test some external devices. If you are not sure whether a problem is caused by the hardware or by the software, you can use the diagnostics programs to confirm that the hardware is working correctly. The diagnostics programs are stored in the upgradeable read-only memory (ROM). IBM Director provides a real-time diagnostics program that tests the major components of the blade server while the server operating system is running. The diagnostics can be downloaded from http://www.ibm.com/pc/support/.

vWhen 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.

vImportant:

1.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.

2.If the server is suspended and a POST error code is displayed, see “POST error codes” on page 79.

3.If the server is suspended and no error message is displayed, see “Error symptoms” on page 87 and “Undetermined problems” on page 101.

4.For information about power-supply problems, see “Power error messages” on page 97.

5.For intermittent problems, check the error log; see “POST error logs” on page 23 and “Diagnostic programs and error messages” on page 25.
