Preface

Introduction

This guide describes how to upgrade Network Appliance^TM filers to the latest release of Data ONTAP^TM firmware and software. It covers all filer models.

Audience

This guide is for system administrators who are familiar with operating systems that run on the filer's clients, such as UNIX®, Windows 95^TM, Windows NT®, and Windows® 2000. It assumes that you know how to use a Web browser.

Terminology

When the term "filer" is used, the information applies to all Network Appliance filer models, including the FAS900 and R100 series of storage appliances.

This guide uses the term "type" to mean pressing one or more keys on the keyboard. It uses the term "enter" to mean pressing one or more keys and then pressing the Enter key.

Where you enter commands

You can enter filer commands either on the system console or from any client computer that can access the filer through a Telnet session.

Command conventions

In examples that illustrate commands executed on a UNIX workstation, this guide uses the command syntax of SunOS 4.1.x. The command syntax and output might differ, depending on your version of UNIX.

Keyboard conventions

When describing key combinations, this guide uses the hyphen
(-) to separate individual keys. For example, "Ctrl-D" means pressing the "Control" and "D" keys simultaneously. Also, this guide uses the term "Enter" to refer to the key that generates a carriage return, although the key is named "Return" on some keyboards.

Typographic conventions

The following table describes typographic conventions used in this guide.

Convention	Type of information
Italic font	Words or characters that require special attention. Placeholders for information you must supply. For example, if the guide says to enter the `arp -d` hostname command, you enter the characters "arp -d" followed by the actual name of the host. Book titles in cross-references.
`Monospaced` font	Command and daemon names. Information displayed on the system console or other computer monitors. The contents of files.
