Introduction
This book describes the procedure for preparing the installation of SUSE® Linux En-
terprise Server on IBM System z systems. It provides all information needed to prepare
the installation on the LPAR and z/VM side.
1 Structure
Basically, this manual is divided in two parts.
General Information and Requirements
This part provides information about the requirements both on the hardware and
the software side that need to be met to install SUSE Linux Enterprise Server suc-
cessfully on your machine.
Preparing for Installation
This part covers the preparation procedure for the installation of SUSE Linux En-
terprise Server on IBM System z. Learn which basic preparations need to be per-
formed on the LPAR and z/VM side. It guides you to the point where YaST, the
SUSE® Linux Enterprise Server installation and conguration tool, takes over.
Additionally, the appendix contains a chapter featuring an overview of possible network
connection types. The second chapter in the appendix focuses on automated system
conguration using the parmle.
TIP: Further Information about SUSE Linux Enterprise Server on IBM
System z
Find a short introduction to SUSE Linux Enterprise Server on IBM System z in
Start-Up Guide of which you received a printed copy. Find a detailed description
of the installation procedure and the administration of SUSE Linux Enterprise
Server in Installation and Administration, which you can nd in the local direc-
tory /usr/share/doc/manual/ or on the rst installation medium in the
directory /docu.

2 Required Background
Several assumptions have been made concerning your background knowledge when
writing this document.
• You are familiar with IBM System z terminology.
• You have a good knowledge of the IBM System z devices attached to your system,
especially its network environment.
• You have a basic understanding of handling a Linux or Unix system.
3 Documentation Conventions
The following typographical conventions are used in this manual:
•/etc/passwd: lenames and directory names
•placeholder: replace placeholder with the actual value
•PATH: the environment variable PATH
•ls,--help: commands, options, and parameters
•user: users or groups
•Alt ,Alt +F1 : a key to press or a key combination; keys are shown in uppercase
as on a keyboard
•File,File →Save As: menu items, buttons
• This paragraph is only relevant for the specied architectures. The arrows mark
the beginning and the end of the text block.
•Dancing Penguins (Chapter Penguins, ↑Reference): This is a reference to a chapter
in another book.

4Further In-Depth Information about
IBM System z
IBM has published a number of very interesting documents about their System z plat-
form. Find them either on the Internet (http://www.redbooks.ibm.com) or in
your installed system (package redbook) under /usr/share/doc/packages/
redbook.
4.1 Hardware
For a rst glance at the technical details of some systems, refer to:
• IBM eServer zSeries 990 Technical Introduction (SG24-6863)
• IBM eServer zSeries 900: Technical Guide (SG24-5975)
• Technical Introduction: IBM eServer zSeries 800 (SG24-6515)
• Linux on zSeries Fibre Channel Protocol Implementation Guide (SG24-6344)
4.2 General Documents about Linux on IBM
System z
A general coverage of Linux on IBM System z can be found in the following documents:
• Linux on IBM eServer zSeries and S/390: ISP and ASP Solutions (SG24-6299)
These documents might not reect the current state of Linux, but the principles of
Linux deployment outlined there remain accurate.

5 Acknowledgments
The history of Linux is a success story about countless developers all around the world
contributing to what originally started as a one-man show by Linus Torvalds. Thanks
to all of them for their tremendous efforts.
Especially we would like to thank all the people involved in the Linux for IBM System
z project at IBM and SUSE. Thanks to the (information) developers at SUSE and IBM,
the test team at SUSE, and all beta-testers and proofreaders at IBM. Thank you for
making SUSE Linux Enterprise Server for IBM System z possible.
