Diagnosing the Problem
This chapter covers the steps that you are recommended to take when an error occurs.
Going through a structured set of tasks helps you to isolate the problem quickly.
IMPORTANT: This guide provides information for multiple servers. Some of the hardware or
software information may not apply to your specific server. You may need to modify some of
the examples or procedures in this guide for your work environment. Refer to your
server-specific user documentation for information on procedures, hardware options, software
tools, and operating systems supported by, and specific to, your server.
The following sections are outlined in this chapter:
• Developing a Troubleshooting Plan
• Preparing to Troubleshoot the Server
• Gathering Information
• Locating Troubleshooting Information
• Contacting HP
Even if you are experienced in troubleshooting, consider skimming through this
chapter before using the remainder of the book and the documentation that shipped
with your server. Otherwise refer to “Locating Troubleshooting Information” in this
chapter, which points you to the appropriate section of this guide.
WARNING: To avoid potential problems, ALWAYS read the warnings and
cautionary information in your server-specific user documentation before
removing, replacing, reseating, or modifying system components.

Developing a Troubleshooting Plan
Evaluate all of the information and symptoms to:
• Identify the problem.
— Prepare the server for diagnosis and familiarize yourself with appropriate
troubleshooting methods using the following section, “Preparing to
Troubleshoot the Server.”
— Collect the facts related to the problem you want to troubleshoot using the
“Gathering Information” section later in this chapter.
— If the problem has not been identified after following the procedures in this
guide, refer to the “Contacting HP” section of this chapter.
• Plan your solution to each problem.
— Identify all steps necessary for implementation of each solution.
— Balance the time and cost required for implementing each solution against
the likelihood of resolving the problem.
— Gather the documentation that shipped with your server. Server-specific user
documentation is also located on the following website:
www.compaq.com/support/servers
Select your server, and then look in the Manuals section.
— Compile a master plan to be sure that you manipulate one variable at a time.
• Identify and collect all tools, such as a Torx screwdriver, electrostatic discharge
(ESD) wrist strap, and software utilities, necessary to troubleshoot the problem.
• Troubleshoot the problem using the information in this guide. Record each action
you take and list the results.
• Test your actions to be sure that the problem is truly resolved.
• Perform preventive steps to stop the problem from recurring. Refer to Chapter 6,
“Error Prevention,” for prevention information.
IMPORTANT: Familiarize yourself with the appropriate warnings for your server by referring
to your server-specific user documentation.

Preparing to Troubleshoot the Server
Before troubleshooting, follow the steps to prepare the server for diagnosis. Also,
read the proper troubleshooting procedures to increase troubleshooting effectiveness.
Preparing the Server for Diagnosis
Before troubleshooting the server:
1. Record any error messages displayed by the system.
2. Remove all diskettes and CDs from the media drives.
3. Power down the server and peripheral devices. Always perform an orderly server
shutdown if possible. This means that you must:
a. Exit the applications.
b. Exit the operating system.
c. Power down the server.
4. Disconnect any peripheral devices not required for testing (any devices not
necessary to power up the server). Do not disconnect the printer if you want to
use it to log error messages.
At this point, you can attempt to boot the server using the steps provided in your
server-specific user documentation to determine if the server is starting as it should.
First, however, read through the proper troubleshooting procedures in the “Using a
Troubleshooting Methodology” section.
Using a Troubleshooting Methodology
As you follow the troubleshooting steps in this guide and your server-specific user
documentation, use the methods described in Table 1-1. When troubleshooting, some
results are obvious, such as error messages or significant changes in functionality.
Other changes may not be as obvious, requiring you to check system logs for new
events recorded after the change was made.
After familiarizing yourself with these troubleshooting methods, follow the steps
outlined in “Gathering Information” in this chapter to troubleshoot your server.

Table 1-1: Troubleshooting Methodology
What to Check Troubleshooting Method
What are the results of each
troubleshooting step?
Look for and record new
symptoms, such as error
messages or informational
messages.
Were the results logical,
consistent, and expected?
Did anything change? If so, what? Check system logs. Look for any
type of change, no matter how
insignificant.
Was any functionality gained or
diminished?
Look for functionality changes to
judge the effectiveness of each
troubleshooting step.
Were any errors made in
implementing a step?
Look for and record any mistakes
made while executing a step.
Was more than one variable changed
at a time?
To be sure that the specific cause
of the problem is isolated, be sure
that during each step only one
variable is changed at a time.
Were any steps skipped or completed
out of order?
Place checkmarks against the
steps as they are executed, and
circle the steps not executed. Look
for skipped steps or steps
executed out of order.
Were any steps accidentally added?
Were any steps added intentionally to
complete or correct another step?
If steps had to be added in order
to proceed, record why, and note
the preceding step.

Gathering Information
If you encounter a problem with your server, follow the guidelines in this section and
record your findings in a notebook. Having these details available reduces
troubleshooting time. This information also helps the authorized service provider to
diagnose and solve your problem, if their assistance is used.
Preliminary Information
Before troubleshooting your specific server problem, collect the following
information:
• What events preceded the failure? After which steps does the problem occur?
• What has been changed between the time the server was working and now?
• Did you recently add or remove hardware or software? If so, did you remember
to change the appropriate settings in the server setup utility, if necessary?
• Was the server recently installed or moved?
• Has the server exhibited problem symptoms for a period of time?
• If the problem occurs randomly, what is the duration or frequency?
To answer these questions, the following information may be useful:
• Run the Survey Utility and compare what has changed (for servers running the
Microsoft Windows NT, Linux, or Novell NetWare operating system).
• Refer to your software and hardware records for information.
After collecting this information, refer to the appropriate section in this chapter:
• When the Server Does Not Start
• When the Self-Tests Fail
