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.

Note
Upgrade procedures for gateway filers (gFilers) are covered in gFiler documentation. The information in this guide does not apply to gFilers.

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.

Accessing Data ONTAP man pages

Network Appliance provides Data ONTAP manual (man) pages for the following types of information. They are grouped into sections according to standard UNIX naming conventions.

Types of information	Man page section
Commands	1
Special files	4
File formats and conventions	5
System management and services	8

Man pages can be viewed in the following ways:

At the filer command line, by entering
```
man command_or_file_name
```
From the FilerView® main navigational page
In the Command Reference Guide
Note
All Network Appliance man pages are stored on the filer in files whose names are prefixed with the string "na_" to distinguish them from client man pages. The prefixed names are used to refer to filer man pages from other man pages and sometimes appear in the NAME field of the man page, but the prefixes are not part of the command, file, or services.

For more information, see the NetApp® man(1) man page.

Terminology and conventions

When the term "filer" is used, the information applies to all Network Appliance filer models, including the 900 series storage appliances and the NearStore® storage appliances.

In examples that illustrate commands executed on a UNIX workstation, the command syntax and output might differ, depending on your version of UNIX.

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, or clicking in a field in a graphical interface and typing information into it.

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.

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.
`Bold monospaced` font	Words or characters you type. What you type is always shown in lowercase letters, unless you must type it in uppercase letters.
