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.
Step 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:
• Hardware components
• Device drivers and firmware
• System software
• UEFI firmware
• System input power or network connections
Step 2. View the light path diagnostics LEDs and event logs. The server is designed for ease of
diagnosis of hardware and software problems.
• Light path diagnostics LEDs: See
“Light path diagnostics” on page 381 for information about
using light path diagnostics LEDs.
• Event logs: See
“Event logs” on page 26 for information about notification events and
diagnosis.
• 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.
Step 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.
To download the latest version of DSA code and the Dynamic System Analysis Installation and
User's Guide, go to
http://www.ibm.com/support/entry/portal/docdisplay?lndocid=SERV-DSA.
Step 4. Check for and apply code updates. Fixes or workarounds for many problems might be available
in updated UEFI firmware, device firmware, or device drivers. To display a list of available updates
for the server, go to
http://www.ibm.com/support/fixcentral/.
Attention: Installing the wrong firmware or device-driver update might cause the server to
malfunction. Before you install a firmware or device-driver update, read any readme and change
history files that are provided with the downloaded update. These files contain important
