Chapter 4. Troubleshooting
This section describes the diagnostic tools and troubleshooting information that are
available to help you solve problems that might occur in the server.
If you cannot diagnose and correct a problem by using the information in this
chapter, see Appendix D, “Getting help and technical assistance,” on page 781 for
more information.

You can solve many problems without outside assistance by following the
troubleshooting procedures in this documentation and on the World Wide Web.
This document describes the diagnostic tests that you can perform, troubleshooting
procedures, and explanations of error messages and error codes. The
documentation that comes with your operating system and software also contains
troubleshooting information.
Diagnosing a problem
Before you contact IBM or an approved warranty service provider, follow these
procedures in the order in which they are presented to diagnose a problem with
your server.
Procedure
1. Return the server to the condition it was in before the problem occurred. If
any hardware, software, or firmware was changed before the problem occurred,
if possible, reverse those changes. This might include any of the following
items:
v Hardware components
v Device drivers and firmware
v System software
v UEFI firmware
v System input power or network connections
2. View the light path diagnostics LEDs and event logs. The server is designed
for ease of diagnosis of hardware and software problems.
v Light path diagnostics LEDs: See “Light path diagnostics” on page 134 for
information about using light path diagnostics LEDs.
v Event logs: See “Event logs” on page 146 for information about notification
events and diagnosis.
v Software or operating-system error codes: See the documentation for the
software or operating system for information about a specific error code. See
the manufacturer's website for documentation.
3. Run IBM Dynamic System Analysis (DSA) and collect system data. Run
Dynamic System Analysis (DSA) to collect information about the hardware,
firmware, software, and operating system. Have this information available
when you contact IBM or an approved warranty service provider. For
instructions for running DSA, see the Dynamic System Analysis Installation and
User's Guide.
