Introduction
Welcome to the Official Red Hat Linux for S/390 Installation Guide.
The Official Red Hat Linux for S/390 Installation Guide contains useful information to assist you
during the installation of Red Hat Linux. From fundamental concepts such as installation preparation
(gathering information about your current system) to the step-by-step installation procedure, this book
will be a valuable resource as you install Red Hat Linux.
This manual will walk you through a typical S/3901installation. Once you have completed the instal-
lation as outlined in this manual, you will have a fully functioning Red Hat Linux system.
Document Conventions
When you read this manual, you will see that certain words are represented in different fonts, type-
faces, sizes and weights. This highlighting is systematic; different words are represented in the same
style to indicate their inclusion in a specific category. The types of words that are represented this way
include the following:
command
Linux commands (and other operating system commands, when used) are represented this way.
This style should indicate to you that you can type in the word or phrase on the command line
and press [Enter] to invoke a command. Sometimes a command contains words that would be
displayed in a different style on their own (e.g., filenames). In these cases, they are considered
to be part of the command, so the entire phrase will be displayed as a command. For example:
Use the cat testfile command to view the contents of a file, named testfile, in the
current working directory.
filename
Filenames, directory names, paths and RPM package names are represented this way. This style
should indicate that a particular file or directory exists by that name on your Red Hat Linux
system. Examples:
The .bashrc file in your home directory contains bash shell definitions and aliases for your
own use.
The /etc/fstab file contains information about different system devices and filesystems.
The /usr/share/doc directory contains documentation for various programs.
Install the webalizer RPM if you want to use a Web server log file analysis program.
1S/390 and zSeries hardware systems are commonly referred to as the mainframe.

vi Introduction
application
This style should indicate to you that the program named is an end-user application (as opposed
to system software). For example:
Use Netscape Navigator to browse the Web.
[key]
A key on the keyboard is shown in this style. For example:
To use [Tab] completion, type in a character and then press the [Tab] key. Your terminal will
display the list of files in the directory that start with that letter.
[key]-[combination]
A combination of keystrokes is represented in this way. For example:
The [Ctrl]-[Alt]-[Backspace] key combination will restart the X Window System.
text found on a GUI interface
A title, word or phrase found on a GUI interface screen or window will be shown in this style.
When you see text shown in this style, it is being used to identify a particular GUI screen or an
element on a GUI screen (e.g., text associated with a checkbox or field). Examples:
On the GNOME Control Center screen, you can customize your GNOME window manager.
SelecttheRequirePasswordcheckbox if you wouldlikeyour screensavertorequireapassword
before stopping.
top level of a menu on a GUI screen or window
When you see a word in this style, it indicates that the word is the top level of a pulldown menu.
If you click on the word on the GUI screen, the rest of the menu should appear. For example:
Under Settings on a GNOME terminal, you will see the following menu items: Preferences,
Reset Terminal,Reset and Clear, and Color selector.
If you need to type in a sequence of commands from a GUI menu, they will be shown like the
following example:
Click on Programs=>Applications=>Emacs to start the Emacs text editor.
button on a GUI screen or window
This style indicates that the text will be found on a clickable button on a GUI screen. For ex-
ample:
Click on the Back button to return to the Web page you last viewed.
computer output

Section 0.1:Document Conventions vii
When you see text in this style, it indicates text displayed by the computer on the command line.
You will see responses to commands you typed in, error messages and interactive prompts for
your input during scripts or programs shown this way. For example:
Use the ls to display the contents of a directory:
$ls
Desktop axhome logs paulwesterberg.gif
Mail backupfiles mail reports
The output returned in response to the command (in this case, the contents of the directory) is
shown in this style.
prompt
A prompt, which is a computer’s way of signifying that it is ready for you to input something,
will be shown in this style. Examples:
$
#
[stephen@maturin stephen]$
leopard login:
user input
Text that the user has to type, either on the command line, or into a text box on a GUI screen, is
displayed in this style. In the following example, text is displayed in this style:
To boot your system into the text based installation program, you will need to type in the text
command at the boot: prompt.
Another example, with the word root displayed as something the user needs to type in:
If you need to log in as root when you first log into your system, and you are using the graphical
login screen, at the Login prompt, type root. At the Password prompt, type in the root
password.
Additionally, we use several differentstrategies todraw yourattention to certain pieces of information.
In order of how critical the information is to your system, these items will be marked as a note, a
caution, or a warning. For example:

viii Introduction
Note
Remember that Linux is case sensitive. In other words, a rose is not a ROSE
is not a rOsE.
CAUTION
Do not do routine tasks as root — use a regular user account unless you need
to use the root account to administer your system.
WARNING
If you choose not to partition manually, a server installation will remove
all existing partitions on all installed hard drives. Do not choose this
installation class unless you are sure you have no data you need to save.
How to Use This Manual
This manual focuses on VM and LPAR-based installations. It will help you prepare your system, walk
you through the installation, and assist you in the configuration of Red Hat Linux.
If you are an experienced user and you do not need a review of the basics, you can skip ahead to
Chapter 2, Installing Red Hat Linux to begin the installation process.
Tip
Refer to the Red Hat Frequently Asked Questions for answers to questions
and problems that may occur before, during, or after the installation. You
will find the FAQ online at:

Section 0.2:How to Use This Manual ix
We Need Feedback!
If you spot a typo in the Official Red Hat Linux for S/390 Installation Guide, or if you have thought of
a way to make this manual better, we would love to hear from you! Please submit a report in Bugzilla
( http://www.redhat.com/bugzilla/) against the component rhl-ig-s390.
Be sure to mention the manual’s identifier:
