This guide describes how to configure, operate, and manage Dell PowerVault F720N,
F740N, and F760N filers that run Data ONTAP 5.3 software. The guide is organized in
three parts:
Chapters 1 through 19 describe how to configure, operate, and manage Dell
PowerVault 720N, 740N, and 760N filers.
Appendix A, Command Reference, provides the commands that you use to
control a filer.
Glossary provides definitions of terms, acronyms, and abbreviations used in
this guide.
$XGLHQFH
This guide is for system administrators who are familiar with operating systems that
run on the filers clients, such as UNIX, Microsoft Windows 9x, and Microsoft
Windows NT. It also assumes that you are familiar with how the Network File System
(NFS), Common Internet File System (CIFS), and Hypertext Transfer Protocol (HTTP)
protocols are used for file sharing or transfers. This guide doesnt cover basic system
or network administration topics, such as Internet Protocol (IP) addressing, routing,
and network topology; it emphasizes the characteristics of the Dell filer.
2WKHU'RFXPHQWV<RX0D\1HHG
Besides this System Administrator and Command Reference Guide, the following
documentation is included with your system:
The Getting Started document provides step-by-step instructions for setting up
your computer system.
The Quick Reference card provides the filer commands and command options.
The Installation and Troubleshooting Guide provides instructions for installing
system hardware and includes troubleshooting and diagnostic procedures for
testing your computer system.

vi
The Users Guide provides instructions for configuring and operating a new filer
that runs Data ONTAP 5.3 software.
You may also have one or more of the following documents.
NOTE: Documentation updates are sometimes included with your system to describe
changes to your system or software. Always read these updates before consulting
any other documentation because the updates often contain the latest information.
Documentation is included with any options you purchase separately from your
system. This documentation includes information that you need to configure and
install these options. Installation instructions for the options are included in the
Installation and Troubleshooting Guide.
Technical information filessometimes called readme filesmay be installed
on your root volume to provide last-minute updates about technical changes to
your system or advanced technical reference material intended for experienced
users or technicians.
7HUPLQRORJ\
This guide uses the following terms:
Filer refers to a PowerVault F720N, F740N, or F760N storage system.
System refers, at a minimum, to a filer and a connected PowerVault F700N
Disk-Array Enclosure (DAE) storage system. A tape backup device can also be a
component of the system, but is not required.
1RWDWLRQDO&RQYHQWLRQV
You can enter filer commands on either the system console or from any client com-
puter that can access the filer through telnet.
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.
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.
.H\&RPELQDWLRQV
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.
