Part I. Installation on x86,
AMD64, Intel EM64T, and
Itanium Processor Family

1
Installation Considerations
This chapter encompasses all the decisions that need to be made before installing SUSE®
Linux Enterprise Server on x86, AMD64, Intel EM64T, and Itanium hardware. Find
the current hardware and software requirements for installing SUSE Linux Enterprise
Server on x86, AMD64, Intel EM64T, and Itanium in the Architecture-Specic Infor-
mation manual, which is contained on the rst CD or DVD as a printable PDF in the
/docu directory.
1.1 Installation Type
SUSE Linux Enterprise Server is normally installed as an independent operating system.
With the introduction of Xen, it is also possible to run multiple instances of SUSE
Linux Enterprise Server on the same hardware. However, the controlling Domain-0
installation for Xen is done like a typical installation with some additional packages.
The installation of Xen guests is described in Installation and Administration, which
is available in the installed system as well as on the rst CD or DVD.
1.2 Boot Methods
Depending on the hardware used, the following boot methods are available for the rst
boot procedure prior to the installation of SUSE Linux Enterprise Server:
Installation Considerations 3

Table 1.1 Boot Options
UseBoot Option
The simplest booting method. The system requires a locally-
available CD-ROM or DVD-ROM drive for this.
CD or DVD drive
Find the images required for creating boot disks on the rst CD
or DVD in the /boot directory. See also the README in the
Floppy or USB
disks
same directory. Booting from a USB memory stick is only pos-
sible if the BIOS of the machine supports booting from it.
Must be supported by the BIOS or by the rmware of the system
used. This option requires a boot server in the network. This
task can be handled by another SUSE Linux Enterprise Server.
PXE or bootp
SUSE Linux Enterprise Server can also be booted from hard
disk. For this, copy the kernel (linux) and the installation
Hard disk
system (initrd) from the /boot/loader directory of the
rst CD or DVD onto the hard disk and add an appropriate entry
to the boot loader.
1.3 Installation Source
When installing SUSE Linux Enterprise Server, the actual installation data must be
available in the network, on a hard disk partition, or on a local CD-ROM or DVD. To
install from the network, you need an installation sever. To make the installation data
available, set up any computer in a Unix or Linux environment as an NFS, HTTP, or
FTP server. To make the installation data available from a Windows computer, release
the data with SMB.
The installation source is particularly easy to select if you congure an SLP server in
the local network. For more information, see Section 4.2, “Setting Up the Server
Holding the Installation Sources” (Chapter 4, Remote Installation, ↑Installation and
Administration).
4Start-Up Guide

1.4 Installation Target
Most installations are to a local hard disk. Therefore, it is necessary for the hard disk
controllers to be available to the installation system. If a special controller, like a RAID
controller, needs an extra kernel module, provide a kernel module update disk to the
installation system.
Other installation targets may be all kinds of block devices that provide sufcient disk
space and speed to run an operating system. This includes network block devices like
iSCSI or SAN. It is also possible to install on network le systems that offer the
standard Unix permissions. However, it may be problematic to boot these, because they
must be supported by the initramfs before the actual system can start. Such instal-
lations are useful if there is a need to start the same system in different locations or if
you intend to use Xen features like domain migration.
1.5 Different Installation Methods
SUSE Linux Enterprise Server offers several different methods for controlling installa-
tion:
• Installation on the console
• Installation via serial console
• Installation with AutoYaST
• Installation via SSH
• Installation with VNC
By default, the console is used. If you have a large number of similar computers to install,
it is advisable to create an AutoYaST conguration le and make this available to the
installation process. See also the documentation for autoyast2 in Chapter 5, Auto-
mated Installation (↑Installation and Administration).

Installation Procedure
This chapter offers an overview of the steps required for the complete installation of
SUSE® Linux Enterprise Server in the required mode. Find detailed information about
the preparations for installing SUSE Linux Enterprise Server on x86, AMD64, Intel
EM64T, and Itanium in the Architecture-Specic Information manual, which is available
as a printable PDF in the /docu directory on the rst CD or DVD. Reference contains
a full description of how to install and congure the system with YaST.
2.1 Booting from a Local
Interchangeable Drive
CD-ROM and oppy drives and USB memory sticks can be used for installation pur-
poses. Adjust your computer to your needs:
1. Make sure that the drive is entered as a bootable drive in the BIOS.
2. Insert the boot medium in the drive and start the boot procedure.
3. The boot menu of the CD, DVD, oppy, or USB disk allows transferring different
parameters to the installation system. See also Section 4.4.3, “Using Custom
Boot Options” (Chapter 4, Remote Installation, ↑Installation and Administration).
If the installation should be performed over the network, specify the installation
source here.
4. If unexpected problems arise during installation, use safe settings to boot.
Installation Procedure 7

2.2 Installing over the Network
An installation server is required to perform the installation by using a network source.
The procedure for installing this server is outlined in Section 4.2, “Setting Up the
Server Holding the Installation Sources” (Chapter 4, Remote Installation, ↑Installation
and Administration).
If you have an SLP server, select SLP as the installation source in the rst boot screen.
During the boot procedure, select which of the available installation sources to use.
If the CDs or DVDs are available in the network, use these as an installation source. In
this case, specify the parameter install=<URL> with suitable values at the boot
prompt. Find a more detailed description of this parameter in Section 4.4.3, “Using
Custom Boot Options” (Chapter 4, Remote Installation, ↑Installation and Administra-
tion).
2.3 Controlling Installation Remotely
There are three options for controlling installations from a remote computer: installation
via SSH, installation over serial console, and installation via VNC. These possibilities
are described in the Architecture-Specic Information manual. Find this manual on the
rst CD or DVD as a printable PDF in the /docu directory.

Part II. Installation on IBM
POWER

3
Installation Considerations
This chapter summarizes all decisions to make before starting an installation of SUSE®
Linux Enterprise Server on IBM POWER hardware. The current hardware and software
requirements for installing SUSE Linux Enterprise Server on IBM POWER devices
are listed in the Chapter 1, Requirements (↑Architecture-Specic Information), provided
as a printable PDF document in the directory /docu on the rst CD.
3.1 Types of Installation
SUSE Linux Enterprise Server offers two different types of installation on IBM
POWER: an installation on the entire system and an installation in a logical partition
(LPAR).
iSeries
Linux can only be installed in an LPAR on this type of machine. The installation
on iSeries requires a telnet connection that allows control over the installation
process throughout its course. An installation server in the network qualies as a
good source of installation.
pSeries
Linux can be installed on the entire system here. On IBM pSeries p630, p655, p670,
and p690, it is also possible to install Linux in an LPAR. You can also start these
two systems without partitioning and install on the entire system (full system par-
tition). A CD-ROM drive, DVD drive, or an installation server in the network can
be used as the installation source.
Installation Considerations 11

eServer i5/p5, System i5/p5, OpenPower
Linux can be installed on the entire system (unmanaged mode) or on an LPAR. A
CD-ROM drive, DVD drive, or an installation server in the network can be used
as the installation source.
JS20 Blade, JS21 Blade
Linux can only be installed on the entire system—on a blade—on this type of ma-
chine. A CD-ROM drive, DVD drive, or an installation server in the network can
be used as the installation source.
IntelliStation, ATX Workstation and Server
Linux can only be installed on the entire system. A CD-ROM drive, DVD drive,
or an installation server in the network can be used as the installation source.
3.2 IPL Options
Depending on the hardware used and on the chosen type of installation, the following
options for the initial IPL are available for installing SUSE Linux Enterprise Server:
Table 3.1 IPL Options
UseIPL Option
Simplest booting procedure. The system requires a locally
available CD-ROM or DVD drive for this.
CD or DVD drive
SUSE Linux Enterprise Server can also be booted from the
network. This requires copying the appropriate kernel
Network
(suseboot/inst64 or ISERIES64) from the rst CD to
a boot server. Booting from network can be selected in the
rmware or with i5/OS.
3.3 Installation Source
For installing SUSE Linux Enterprise Server, the installation les must be available in
the local network or on a locally provided CD-ROM or DVD. Provide a network source
12 Start-Up Guide

by setting up a Linux or Unix system as an HTTP, NFS, or FTP server. It is also possible
to share the installation les over SMB from a computer running Windows.
Conguring an SLP server in the local network simplies selection of an installation
source. This is described in Section 4.2.1, “Setting Up an Installation Server Using
YaST” (Chapter 4, Remote Installation, ↑Installation and Administration).
3.4 Installation Targets
SUSE Linux Enterprise Server can be installed on different types of mass storage media
on IBM Power.
iSeries
• DASD (hard disk)
• IBM iSeries virtual disk
pSeries
• DASD (hard disk)
• SAN over Fiber Channel
eServer i5/p5, System i5/p5, OpenPower
• DASD (hard disk)
• Virtual SCSI
• SAN over Fiber Channel
JS20 Blade, JS21 Blade
• Local hard disk
IntelliStation, ATX Workstation and Server
• Local hard disk
Installation Considerations 13

3.5 Connecting to the Installation
System
SUSE Linux Enterprise Server offers a selection of four different ways of connecting
to the installation system: SSH, VNC, serial console, and screen console. The versions
of the SSH, VNC, or terminal software vary depending on the operating system running
on the workstation initiating the connection to the installation system.
It is advisable to create an AutoYaST conguration le if many identical partitions or
machines need to be installed. It can then drive the installation process. Refer to the
documentation for AutoYaST in Section 5.2, “Rule-Based Autoinstallation” (Chapter 5,
Automated Installation, ↑Installation and Administration).
