Preface

Introduction

This guide describes how to use NetApp® storage appliances, such as FAS800 or FAS900 Series Enterprise Servers, or filers and in a SAN environment, how to create and manage LUNs and initiator groups (igroups), and how to monitor SAN protocols.

Audience

This guide is for system administrators who are familiar with operating systems such as UNIX® and Windows 2000®, that run on the filer's clients. It also assumes that you know how to configure the filer and you know how Network File System (NFS), Common Internet File System (CIFS), and Hypertext Transport Protocol (HTTP) are used for file sharing or transfers and how FCP and iSCSI are used for block sharing or transfers. This guide doesn't cover basic system or network administration topics, such as IP addressing, routing, and network topology.

Terminology

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

This guide uses the following terms:

Enter refers to pressing one or more keys and then pressing the Enter key.
LUN refers to a logical unit number, which represents a logical unit of storage.
LUN ID refers to the numerical identifier for a LUN.
Type refers to pressing one or more keys on the keyboard

Command conventions

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

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.
`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.
