Section 1.1:Documentation Conventions 5
1 Introduction
Welcome to the Official Red Hat Linux iSeries Installation Guide.
The Official Red Hat Linux iSeries Installation Guide contains useful information to assist you during
the installation of Red Hat Linux. From fundamental concepts such as installation preparation (gath-
ering 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 installation using the Red Hat Linux CD-ROMs. Once
you have completed the installation as outlined in this manual, you will have a fully functioning Red
Hat Linux desktop system.
WARNING
In order to complete the installation process, you must follow all steps as
given in Section 3.22, Installation Complete. If these steps are not appro-
priately followed, you will not have a fully functioning Red Hat Linux
iSeries installation.
1.1 Documentation 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 (like 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

6 Chapter 1:Introduction
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.
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.
Combinations of keystrokes
A combination of keystrokes is represented like this: [key]-[key]. For example:
The [Ctrl]-[Alt]-[Backspace] key combination will restart the X Window System.
Sequences of commands in Graphical User Interface (GUI) menus
If you need to type in a sequence of commands from a GUI menu, they’ll be shown similar to
the following example:
Click on Programs=>Applications=>Emacs to start the Emacs text editor.
Additionally, we use several differentstrategies to draw your attention to certain piecesof 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:
Note
Remember that Linux is case sensitive. In other words, a rose is not a ROSE
is not a rOsE.

Section 1.2:How to Use This Manual 7
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-class installation will
remove all data on hard drives assigned to the Linux logical partition
you are installing on. See Appendix C, Re-installation of Red Hat Linux
and Preserving Existing Data for information regarding saving existing
data before reinstalling, or consider a differentinstallation class that will
preserve your data.
1.2 How to Use This Manual
This manual focuses on a CD-ROM based installation, so it is ideal for users (both new and old) who
want a quick and simple installation solution. 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 who wants to perform a Red Hat Linux CD-ROM installation, and you
do not need a review of the basics, you can skip ahead to Chapter 3, 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:
http://www.redhat.com/support/docs/faqs/rhl_general_faq/FAQ.html

Section 2.3:iSeries Hardware Preparation for Installation 9
2 Steps to Get You Started
Before you install Red Hat Linux, you will need to perform the following steps:
2.1 Checking For Additional Hardware-Specific
Documentation
The installation process assumes basic familiarity with the IBM iSeries platform and makes
reference to IBM’s Configuring Linux in a Guest Partition. In general, this section assumes
that you have read the Configuring Linux in a Guest Partition document ( http://publib.boul-
der.ibm.com/pubs/html/as400/v5r1/ic2924/info/rzalm/rzalmlinuxkickoff.htm) in its entirety.
2.1.1 Additional Resources
For more information on iSeries hardware, refer to the following resources.
Useful Websites
•Configuring Linux in a Guest Partition — http://publib.boul-
der.ibm.com/pubs/html/as400/v5r1/ic2924/info/rzalm/rzalmlinuxkickoff.htm
• Linux for iSeries — http://www-1.ibm.com/servers/eserver/iseries/linux/
2.2 Where to Find Other Red Hat Linux Manuals
If your particular boxed set did not include all of the printed Red Hat Linux manuals, you can find
them online or on the Red Hat Linux Documentation CD.
To find the manuals in both HTML and PDF formats online, visit http://www.redhat.com/sup-
port/manuals.
2.3 iSeries Hardware Preparation for Installation
In order to prepare your iSeries system for installation, you should follow the instructions in the Plan-
ning to run Linux on a logical partition and Creating a logical partition to run Linux sections of the
Configuring Linux in a Guest Partition document.
The virtual LAN interface may be configured for DHCP or a static IP address. Consult your OS/400
command documentation for information on configuring the OS/400 facilities. The partition may be
configured for IPL type A, B, or *NWSSTG. If IPL type *NWSSTG is used, a 4 MB PReP Boot
(primary, active) partition is required on the first virtual disk.

10 Chapter 2:Steps to Get You Started
2.4 Do You Have Enough Disk Space?
Nearly every modern-day operating system (OS) uses disk partitions, and Red Hat Linux is no ex-
ception. When you install Red Hat Linux, you may have to work with disk partitions. If you have not
worked with disk partitions before (or need a quick review of the basic concepts) read An Introduction
to Disk Partitions in the appendix of the Official Red Hat Linux Reference Guide before proceeding.
You must ensure that Red Hat Linux has enough available disk space on the hard drive(s) for this
installation.
These disks, especially virtual disks, must be made large enough for your maximum needs before the
installation. For the iSeries, it is not necessary to share these disks with other Linux partitions or with
other operating systems. Plan your disk space accordingly for the partitions where Red Hat Linux will
be installed.
Before you start the installation process, one of the following conditions must be met:
• Your computer must have enough unpartitioned disk space for the installation of Red Hat Linux.
• You must have one or more partitions that may be deleted, thereby freeing up enough disk space
to install Red Hat Linux.
2.4.1 Installation Disk Space Requirements
Workstation-class
A workstation-class installation, choosing to install GNOME or KDE, requires at least 1.2 GB
of free space. Choosing both GNOME and KDE requires at least 1.5 GB of free disk space.
Server-class
A server-class installation requires 650 MB for a minimal installation and at least 1.2 GB of free
space if every package is selected.
Custom-class
A custom-class installation requires 300 MB for a minimal installation and at least 2.4 GB of
free space if every package is selected.
Note
To use automatic partitioning, you must have enough free disk space avail-
able (1.2 GB or more); if you do not have enough free disk space available,
this option will not appear during your installation.
