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 call 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 130 for

information about using light path diagnostics LEDs.

v Event logs: See “Event logs” on page 141 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 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 your approved warranty service provider. For instructions for running

DSA, see the Dynamic System Analysis Installation and User's Guide.
