6 Troubleshooting HP APA

This chapter contains a diagnostic map to help you solve problems that might occur when you use HP APA. Use this chapter with the appropriate HP and third-party switch documentation to solve as many problems as possible at your level.

Operation

Network problems can occur for a number of reasons. The diagnostic map in this chapter help you to isolate the problem. The following figure explains how to use the diagnostic map:

The left-hand column asks questions about the status of specific events that occur as you use the system.

The right-hand column diagnoses negative responses to those questions.

After you isolate the problem, the map refers you to other chapters for instructions on using the various problem solving tools and utilities. The map also refers you to other manuals for more complete diagnostic information for particular devices and software products.

You might experience problems that are not documented in this manual when you use the HP APA software with other products. See the documentation for the other products for additional information.

Getting Started

Before you start troubleshooting, ensure that the communications hardware is ready for use. Verify the following:

•The system's physical cable connections (the Ethernet connection and the transceiver connection) are properly installed. See the documentation for your system and the NIC.

•Event logging is enabled in order to monitor network events. For information about the Network Tracing and Logging (NetTL) tool, see “nettl Tracing and Logging Tool” (page 90). For information about logging messages to syslog, see “Logging Messages to the syslog.log File” (page 63).

Also see the product release notes for up-to-date information on known problems.
