Preface

Introduction

This guide describes how to upgrade NetApp® storage systems to the latest release of Data ONTAP® firmware and software. It covers all storage system models that run Data ONTAP 7.1 and higher; see the Data ONTAP 7.1 Release Notes for more information about supported storage systems.

Note
Upgrade procedures for gateway filer (V-Series, formerly known as gFiler^TM) systems are covered in V-Series documentation. The information in this guide does not apply to V-Series systems.

Audience

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

Accessing Data ONTAP man pages

Data ONTAP manual (man) pages are available 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 storage system command line, by entering
```
man command_or_file_name
```
From the FilerView® main navigational page
In Commands: Manual Page Reference, Volumes 1 and 2
Note
All Data ONTAP man pages are stored on the storage system 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 storage system 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 man(1) man page.

Terminology

Storage systems that run Data ONTAP are sometimes referred to as filers, storage appliances, appliances, or systems. The name of the graphical user interface for Data ONTAP, FilerView, reflects one of these common usages.

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.

FilerView as an alternative to commands

Tasks you perform as a Data ONTAP administrator can be performed by entering commands at the storage system console, in configuration files, or through a Telnet session or a Remote Shell connection.

Another method of performing many common tasks is to use the FilerView® graphical management interface for viewing and managing storage system from a Web browser. FilerView comes with every storage system, is easy to use, and includes Help that explains Data ONTAP features and how to work with them in FilerView.

For more information about accessing a storage system with FilerView, and about FilerView Help, see the System Administration Guide.

Command conventions

In examples that illustrate commands executed on a UNIX workstation, 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.
`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.
