Introduction
This book describes the procedure for preparing the installation of SUSE® Linux Enterprise 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 successfully on your machine.
Preparing for Installation
This part covers the preparation procedure for the installation of SUSE Linux Enterprise Server on IBM System z. Learn which basic preparations need to be performed on the LPAR and z/VM side. It guides you to the point where YaST, the
SUSE® Linux Enterprise Server installation and conguration 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
conguration using the parmle.

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.
Introduction ix
General Information and
Requirements
This chapter gives basic information about the system requirements, like supported
hardware, level of MicroCode, and software. It also covers the different installation
types, how to do an IPL for the rst installation, and information about the IOCDS.
1.1 System Requirements
This section provides a list of hardware for IBM System z supported by SUSE® Linux
Enterprise Server. Next, the level of the MicroCode (MCL) used in your IBM System z
system, which is very important for the installation, is covered. Additional software to
install and use for installation is mentioned at the end of this section.
1.1.1 Hardware
SUSE Linux Enterprise Server has run successfully on the following platforms:
• IBM eServer zSeries 800 (z800) 2066
• IBM eServer zSeries 890 (z890) 2086
1
• IBM eServer zSeries 900 (z900) 2064
• IBM eServer zSeries 990 (z990) 2084
• IBM eServer Series z9 (z9-EC) 2094
General Information and Requirements 1
• IBM eServer Series z9 (z9-BC) 2096
Memory Requirements
Different installation methods have different memory requirements during installation.
After installation is completed, the system administrator may reduce memory to the
desired size. SUSE recommends using:
512 MB
For installation from NFS, FTP, or SMB installation sources
or whenever VNC is used.
For installation under z/VM.768 MB
For installation under LPAR.1 GB
Disk Space Requirements
2 GB disk space is required for the installation of SUSE Linux Enterprise Server.
Network Connection
A network connection is needed to communicate with your SUSE Linux Enterprise
Server system. This can be one or more of the following connections or network cards:
• OSA-2 (Token Ring and Ethernet, only available on z900)
• OSA Express Ethernet (including Fast and Gigabit Ethernet)
• OSA Express High-Speed Token Ring (only available on z800, z900, z890, and
z990)
• HiperSockets or Guest LAN
• 10 GBE, VSWITCH
The following interfaces are still included, but no longer supported:
• CTC (or virtual CTC)
2 Architecture-Specic Information
• ESCON
• IP network interface for IUCV
IPL Options
For an LPAR installation, the Load from CD-ROM or Server option is the preferred
way to IPL the installation kernel and initrd (initial RAM disk). If this option is not
available and you cannot use z/VM for installing the system, you need to IPL from a
channel attached tape with the tapeipl kernel, the parmle, and the initrd. Thus, you
need access to a tape unit (3480, 3490, or 3590, for example).
1.1.2 MicroCode Level, APARs, and Fixes
This release of SUSE Linux Enterprise Server is based on the October 2005 codestream
from IBM developerWorks (http://www.ibm.com/developerworks/linux/
linux390/october2005_technical.html). The restrictions and requirements
listed at the Web site also apply for this release of SUSE Linux Enterprise Server, except
where stated differently in this manual.
It is recommended always to use the highest service level available. For installation
under VM, you need at least z/VM 4.2 with service level 0103. To use HiperSockets
under VM on z900 (2064), you need MicroCode EC E26949 level 013 or higher. For
an IPL from SCSI on z900, you need SCSI enabler MCL, feature code 9904, EC J12811.
For the installation of SUSE Linux Enterprise Server on IBM System z, the MicroCode
levels and z/VM APARs outlined in the following are required.
OSA-Express QDIO
zSeries 990
Driver 52G, EC, J12558 at level 116 or later
zSeries 890
Driver 52G, EC, J12558 at level 116 or later
zSeries 900
Driver 3G, OSA microcode level 3.0A
General Information and Requirements 3
MCLs: J11204.007 and J11204.008 (available May 3, 2002)
zSeries 900
Driver 3C, OSA microcode level 2.26
MCLs: J10630.013 and J10630.014 (available May 20, 2002)
zSeries 800
Driver 3G, OSA microcode level 3.0A
MCLs: J11204.007 and J11204.008 (available May 3, 2002)
VM/ESA and z/VM
z/VM 5.2
z/VM 5.1
z/VM 4.4
All necessary xes and enhancements included.
Level RSU 0402 is required to implement z990 Queued I/O Assist. Find more information at http://www.vm.ibm.com/perf/aip.html.
Negotiate the order of installation with your IBM support, because it might be necessary
to activate the VM APARs before installing the new MicroCode levels.
1.1.3 Software
To install SUSE Linux Enterprise Server via non-Linux–based NFS or FTP, you might
experience problems with NFS or FTP server software. Especially the Windows standard
FTP server can cause errors, so installing via SMB on these machines is generally recommended.
To connect to the SUSE Linux Enterprise Server installation system, one of the following
methods is required:
SSH with Terminal Emulation (xterm compatible)
SSH is a standard Unix tool that should be present on any Unix or Linux system.
For Windows, there is an SSH client called Putty. It is free to use and is included
4 Architecture-Specic Information
on CD 1 in the directory /dosutils/putty. Get more information about Putty
at http://www.chiark.greenend.org.uk/~sgtatham/putty/.
VNC Client
For Linux, a VNC client called vncviewer is included in SUSE Linux Enterprise
Server as part of the XFree86-Xvnc package. For Windows, a VNC client is
included in the present SUSE Linux Enterprise Server. Find it in /dosutils/
tightvnc of CD 1. Copy the tightvnc-1.2.9-setup.exe le to the hard
disk of your Windows machine and install it. Alternatively, use the VNC Java client
and a Java-enabled Web browser.
X Server
Find a suitable X server implementation on any Linux or Unix workstation. There
are many commercial X Window System environments for Windowsand Macintosh.
Some of them can be downloaded as free trial versions. A trial version of the Mocha
X Server from MochaSoft can be obtained at http://www.mochasoft.dk/
freeware/x11.htm.
TIP: Additional Information
Consult the README located in the highest directory of CD 1 of your SUSE
Linux Enterprise Server before installing SUSE Linux Enterprise Server on IBM
System z. This le completes the documentation presented in this book.
1.2 Installation Types
This section gives an overview of the different types of installation possible with SUSE
Linux Enterprise Server for IBM System z. Basically, these two types are given:
LPAR
Installation of SUSE Linux Enterprise Server using a logical partition (LPAR).
VM (z/VM)
Installation of SUSE Linux Enterprise Server as as a guest operating system within
z/VM.
Depending on the mode of installation (LPAR or VM), there are different possibilities
for starting the installation process and IPLing the installed system.
