Preface

About this guide

This guide describes how to monitor, troubleshoot, and perform maintenance for Network Appliance^TM gFiler^TM gateways.

Audience

This guide is for support engineers who are familiar with operating systems, such as UNIX®, Windows® 95, Windows NT®, and Windows 2000, and who will be installing gFiler gateways. This guide doesn't cover basic system or network administration topics, such as IP addressing, routing, and network topology; it emphasizes the characteristics of the NetApp® gFiler.

Terminology

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.

This guide uses the following terms:

Storage subsystem refers to your disk array
Node refers to either the local or partner gFiler.
Cluster refers to local and partner nodes directly connected to each other.

Command conventions

You can enter commands on the system console or from any client that has access to the system using Telnet. In examples of 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.
