Getting started

NOTE: For common troubleshooting procedures, the term "server" is used to mean servers and server blades.

This guide provides common procedures and solutions for the many levels of troubleshooting a ProLiant server—from the most basic connector issues to complex software configuration problems.

To understand the sections of this guide and to identify the best starting point for a problem, use the following descriptions:

•Common problem resolution (on page 15)

Many server problems are caused by loose connections (on page 15), outdated firmware ("Updating firmware" on page 15), and other issues. Use this section to perform basic troubleshooting for common problems.

•Problem diagnosis

When a server exhibits symptoms that do not immediately pinpoint the problem, use this section to begin troubleshooting. The section contains a series of flowcharts that provide a common troubleshooting process for troubleshooting ProLiant servers. The flowcharts identify a diagnostic tool or a process to solve the problem.

•Hardware problems (on page 32)

When the symptoms point to a specific component, use this section to find solutions for problems with power, general components, system boards, system open circuits and short circuits, and external devices.

•Software problems (on page 49)

When you have a known, specific software problem, use this section to identify a solution to the problem.

•Software tools and solutions (on page 54)

Use this section as a reference for software tools and utilities.

•HP resources for troubleshooting (on page 69)

When additional information becomes necessary, use this section to identify websites and supplemental documents that contain troubleshooting information.

•Error messages

Use this section to locate a complete list of ADU error messages (on page 73), POST error messages and beep codes (on page 92), event list error messages (on page 124), HP BladeSystem infrastructure error codes (on page 127), and Port 85 codes and iLO messages (on page 131).
