Preface

The Netra 440 Server Diagnostics and Troubleshooting Guide is intended to be used by experienced system administrators. It includes descriptive information about the Netra trademark 440 server and its diagnostic tools, and specific information about diagnosing and troubleshooting problems with the server.

Before You Read This Book

This book assumes that you are familiar with computer network concepts and terms, and have advanced familiarity with the Solaris trademark Operating System (Solaris OS).

To use the information in this document fully, you must have thorough knowledge of the topics discussed in the Netra 440 Server System Administration Guide (817-3884-xx).

How This Book Is Organized

The first part of this book is organized a bit differently from others with which you may be familiar. Each chapter contains either conceptual or procedural material, but not both. Turn to the conceptual chapters to get the background information you need to understand the context of the tasks you must perform. Turn to the procedural chapters for quick access to step-by-step instructions with little or no explanatory material.

The chapters in the second part of this book, as well as the Appendix, contain a mixture of procedural and conceptual material.

To help you locate information quickly, the first page of each chapter contains a list that summarizes the topics covered in that chapter. Reference material appears as needed at the end of each chapter.

This book is divided into two parts. Part I covers diagnostic tools.

Chapter 1, a conceptual chapter, provides an overview of the diagnostic tools available for use with the Netra 440 server.

Chapter 2, a conceptual chapter, provides detailed information about the uses and capabilities of the various diagnostic tools and explains how they are related to each other.

Chapter 3, a procedural chapter, provides instructions for isolating failed parts.

Chapter 4, a procedural chapter, provides instructions for monitoring the system.

Chapter 5, a procedural chapter, provides instructions for exercising the system.

Part II of this book covers troubleshooting.

Chapter 6, a conceptual and procedural chapter, explains the troubleshooting options available to you and provides instructions for implementing troubleshooting options.

Chapter 7, a conceptual and procedural chapter, explains troubleshooting approaches and provides instructions for troubleshooting hardware problems.
