this documentation and on the World Wide Web.
This document describes the diagnostic tests that you can perform, troubleshooting procedures, and 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 a Lenovo-approved warranty service provider, perform the following steps 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 action might involve 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, event logs, and error codes.
The following items are
available to help you diagnose hardware and software problems easily:
•
Light path diagnostics LEDs
(see “Light path diagnostics” on page 53)
•
Event logs
•
Software or operating-system error codes
(see the documentation or tips on the
manufacturer's Web site)
Step 3.
Run Lenovo Dynamic System Analysis (DSA) and collect the 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 on how to run 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

Step 4.
Check for and apply code updates.
