Troubleshooting Overview
Troubleshooting data communications problems may require you to
investigate many hardware and software components. Some problems
can be quickly identified and resolved. These include invalid software
installation, version incompatibilities, insufficient HP-UX resources,
corrupt configuration shell scripts, and programming or command errors.
Other problems require more investigation.
Once identified, most problems can be resolved by the programmer, user,
or node manager, using the suggestions in this chapter or the error
messages documented in the link installation manuals. However, there
may be problems that you should report to your Hewlett-Packard
support contact. This chapter includes guidelines for submitting an HP
Service Request (SR).
This section discusses the following topics:
• “Characterizing a Problem” on page 99
• “Diagnostic Tools Summary” on page 100
• “Diagnosing Repeater and Gateway Problems” on page 102
Characterizing a Problem
It is important that you ask questions when trying to characterize a
problem. Start with global questions and gradually get more specific.
Depending on the response, ask another series of questions until you
have enough information to understand exactly what happened. Key
questions to ask are as follows:
• Does the problem seem isolated to one user or program? Can the
problem be reproduced? Did the problem occur under any of the
following circumstances:
— When running a program?
— When issuing a command?
— When using a nodal management utility?
— When transmitting data?
