Applies to SUSE Linux Enterprise Server for SAP Applications 11 SP4

2 Default Installation Scenarios

After planning the installation with downloading the software and checking the minimal hardware requirements, there are three default installation scenarios:

2.1 Planning the Installation

Plan the installation with downloading the software and checking the minimal hardware requirements.

2.1.1 Download and Installation Preparations

  1. Download the DVD 1 ISO image of SUSE® Linux Enterprise Server for SAP Applications 11 (electronic media kit).

  2. Burn the image onto a physical DVD and ensure that it is bootable. Alternatively, you might use a virtual CD-ROM device for installation into a virtual machine.

2.1.2 Hardware Requirements

CPU

64bit (x86_64).

Hard Disk

For the Installation with Wizard, at least 10 GB hard disk space for the system volume plus space for the swap partition and 200 GB for the data partition are required.

2.2 Booting the Installation Medium

Different scenarios are available to install SUSE Linux Enterprise Server for SAP Applications 11. Select the preferred installation scenario from the DVD boot menu.

Note
Note: Installing on the POWER Architecture

Since version 11 SP4, SUSE Linux Enterprise Server for SAP Applications supports the POWER architecture. On POWER, you perform a SUSE Linux Enterprise Server standard installation as outlined in the SLES Deployment Guide. Then you finish the installation of the product with the SAP Product Installation.

On POWER, Installation with Wizard is not available.

DVD Boot Menu

SLES for SAP Applications — Installation (see Section 2.3, “SLES for SAP Applications — Installation)

A standard SLES installation prepared for installing SAP applications later. You can install SAP applications with 3rd party installation routines.

This scenario is suitable for experienced administrators who want to install SUSE Linux Enterprise Server for SAP Applications according to their own plan. The default package selection is already adapted to SAP installations.

SLES for SAP Applications — Installation with Wizard (see Section 2.4, “SLES for SAP Applications — Installation with Wizard)

This is a guided installation of the operating system and an SAP application. After the installation of the operating system the SAP Installation Wizard will start for installation of a validated SAP solution.

SLES for SAP Applications — Installation with External Profile (see Section 2.5, “SLES for SAP Applications — Installation with External Profile)

This installation is driven by a user-provided AutoYaST profile. There are no SUSE-provided SAP optimizations.

This scenario is suitable for experienced users who are familiar with AutoYaST and want to deploy their own AutoYaST profiles to install SUSE Linux Enterprise Server for SAP Applications.

Rescue System

Starting a minimal Linux system without a graphical user interface. For more information, see the Administration Guide, Chapter 34, Common Problems and Their Solutions; find the Administration Guide at https://documentation.suse.com/sles/11-SP4/.

Memory Test

Testing the system RAM using repeated read and write cycles. For more information, see the Administration Guide Chapter 34, Common Problems and Their Solutions.

2.3 SLES for SAP Applications — Installation

The first part is a standard manual SUSE Linux Enterprise Server installation; for details about such a SLES installation, see the SLES Deployment Guide, Chapter 6, Installation with YaST. In addition, the SAP Application Server Base (sap-loc and sapconf) pattern will be installed by default and basic settings will be configured.

You will be prompted for all common installation settings, like partitioning of storage devices, network, or software packages.

2.4 SLES for SAP Applications — Installation with Wizard

This is a guided installation of the operating system with optimized settings for SAP applications.

During this installation scenario, the following installation and configuration steps will take place and interactive settings are required or possible.

2.4.1 Data Required for Installing the System (with Wizard)

The following data is required for the SUSE Linux Enterprise Server part of the installation (required per physical server):

Hostname

Domain

IP address

Subnet mask

Domain searchlist (DNS)

IP for name server

IP for gateway

Master password for the system installation (root password)

The following data is required for the SAP part of the installation (required per SAP system):

SAP System ID of the system to be built up

Virtual hostname (*)

Virtual IP address for SAP service (*)

Virtual netmask (*)

Instance number of the SAP system

Solution Manager key for the SAP system (*)

System T-Shirt Sizing (S, M, L, or customer-specific size) (*)

Database Log Mode (*)

(*) not required for TREX.

2.4.2 Selecting SLES for SAP Applications — Installation with Wizard from the DVD Boot Menu

From the DVD boot menu (see Figure 2.1, “DVD Boot Menu”), select SLES for SAP Applications — Installation with Wizard. The installation process loads and configures a Linux system with all requirements for an SAP installation. To view the boot messages and copyright notices during this process, press Esc. On completion of this process, the YaST installation program starts and displays the graphical installer, which will run mostly automatically.

2.4.3 Preparing System for Automated Installation

After analyzing your computer, the next YaST pop-up dialog will let you specify the volume configuration. Here you configure the volume for the system and swap space. The data volume comes later, after you select the SAP Application.

System Volume Configuration
Figure 2.2: System Volume Configuration

If there is just one hard disk, keep it as the system volume device and set the size of the system volume (and the swap space) in GB in the lower field and confirm it; see Figure 2.2, “System Volume Configuration”.

Tip
Tip: Size of the System Volume

Normally, at least 10 GB is required for the system volume. The swap space depends on the available main memory (RAM). For more information, see the SAP Note 1597355: https://launchpad.support.sap.com/#/notes/1597355.

If there is more than one hard disk, select the right one as the system volume device and set the size of the system volume (and the swap space) in GB in the lower fields and confirm it. For more information about partitioning, see Chapter 3, Background Information on Partitioning.

Warning
Warning: Deleting Data

If you confirm the storage volume configuration, all existing data on the hard disk will be deleted. If you do not want this to happen, turn off the system.

After confirmation, YaST performs the software installation. Packages are installed one by one, so you can see the progress.

2.4.4 Password for the System Administrator root

When all packages are installed, the basic installation is finished, and the system is rebooted for initial configuration, you will be prompted to enter a Password for the System Administrator root; see Figure 2.3, “Password for root User”.

Password for root User
Figure 2.3: Password for root User

root is the name of the superuser, or the administrator of the system. Unlike regular users (who may or may not have permission to access certain areas or execute certain commands on the system), root has unlimited access to change the system configuration, install programs, and set up new hardware. The root account should only be used for system administration, maintenance, and repair. Logging in as root for daily work is rather risky: a single mistake could lead to irretrievable loss of system files.

For verification purposes, the password for root must be entered twice. Do not forget the root password. Once entered, this password cannot be retrieved.

The root password can be changed any time later in the installed system. To do so, run YaST and start Security and Users › User and Group Management.

Warning
Warning: The root User

The root user has all the permissions needed to make changes to the system. To carry out such tasks, the root password is required. You cannot carry out any administrative tasks without this password.

2.4.5 Hostname, Domain Name, and IP Address

The next dialog starts with the network configuration; see Figure 2.4, “Hostname, Domain Name, and IP Address”.

Hostname, Domain Name, and IP Address
Figure 2.4: Hostname, Domain Name, and IP Address

The Hostname is the computer’s name in the network. The Domain Name is the name of the network. A hostname and domain are proposed by default. If your system is part of a network, the hostname has to be unique in this network, whereas the domain name has to be common to all hosts on the network.

Also enter the IP Address and Netmask for this host. The IP address must be unique and the netmask has to be common to all hosts on the network.

2.4.6 Domain Name Service (DNS) and Time Server (NTP)

The next dialog continues with the network configuration; see Figure 2.5, “Domain Name Service (DNS) and Time Server (NTP)”.

Domain Name Service (DNS) and Time Server (NTP)
Figure 2.5: Domain Name Service (DNS) and Time Server (NTP)

For Domain Name Service (DNS) configuration, enter the Domain Searchlist and the IP Address of DNS Server plus the IP address of the Default Gateway of your network.

Also enter the address of the NTP Server to synchronize automatically via Network Time Protocol (NTP).

2.4.7 Registration

To get technical support and product updates, you need to register and activate your product with the Novell Customer Center; see Figure 2.6, “Registration”. This dialog provides assistance for doing so. Find detailed information about Novell Customer Center at http://www.novell.com/documentation/ncc/.

Registration
Figure 2.6: Registration

Enter your E-Mail Address and Registration Code for the product. If you provide the registration code now, operating system updates will be installed automatically during the installation of the system.

2.4.8 System Configuration Settings

After confirming the registration data, the system will be configured with the supplied settings.

No user action is required at this stage.

Warning
Warning: Firewall Disabled

This wizard-based installation scenario disables the firewall (SuSEfirewall2) completely.

If needed, you can activate the firewall after the installation. If you activate the firewall after the installation, you must open all required ports manually. For more information about required ports, see Section 5.3.2, “Ports Configuration”.

2.4.9 SAP Product Installation

After an automatic reboot and applying previously supplied configuration settings, you are prompted to continue with the SAP Product Installation using the SAP Installation Wizard. The SAP Installation Wizard will install the SAP application from the SAP media kits you received from SAP.

Tip
Tip: SAP Product Installation Default Settings

The SAP Product Installation default settings are specified and documented in /etc/sysconfig/sap-installation-wizard. You can change them according to your needs.

Procedure 2.1: SAP Product Installation
  1. Select Create SAP file systems and start SAP product installation and confirm the pop-up (see Figure 2.7, “SAP Product Installation”) if you want to continue with the installation right away.

    Otherwise, it is possible to just prepare the SAP product installation with Only create SAP Business One file systems, do not install SAP products now, or completely interrupt the installation process at this point with Finish wizard and proceed to OS login and resume it after a system restart.

    Important
    Important: Creating SAP Business One File Systems Only Works On Hardware Certified for Business One

    To use the functionality Only create SAP Business One file systems, do not install SAP products now, your hardware needs to be certified for Business One. Additionally, follow the hardware setup instructions in SAP Note 1944415: Hardware Configuration Guide and Software Installation Guide for SUSE Linux Enterprise Server with SAP HANA and SAP Business One (https://launchpad.support.sap.com/#/notes/1944415).

    Otherwise, this option will not create a new file system and the installation workflow ends at this point.

    SAP Product Installation
    Figure 2.7: SAP Product Installation
    Tip
    Tip: Resuming SAP Installation after System Restart

    To resume the SAP installation with the wizard, start YaST and select the SAP Product Installer (Computer, then in the YaST Control Center click Miscellaneous › SAP Product Installer; see Figure 2.8, “YaST Control Center: SAP Product Installer”). The functionality is the same, but the layout of the dialogs is different; the left progress pane is only displayed when continuing with the installation without a restart.

    The following screen shots document the installation with the SAP Product Installer that runs after a restart of the system.

    YaST Control Center: SAP Product Installer
    Figure 2.8: YaST Control Center: SAP Product Installer
  2. In the next dialog provide the Location of the SAP Installation Master; see Figure 2.9, “SAP Installation Wizard: SAP Installation Master Location”. The location can either be a local source or a remotely provided installation source.

    Local Source
    • a directory (dir:// and /path/to/dir/)

    • a locally connected hard disk (device:// and devicename/path/to/dir/on/device)

    • a USB mass storage (usb:// and /path/to/dir/on/USB)

    • a CD-ROM (cdrom://)

    A Remotely Provided Installation Source
    • NFS (nfs:// and server_name//path/to/dir/on/server)

    • SMB (smb:// and [username:password@]server_name//path/to/dir/on/server[?workgroup=workgroup_name])

    —select the corresponding option from the pull-down list on the left.

    Tip
    Tip: Remote Location Specification

    If you want to install from an NFS source, you must enter the name of the server and the complete path to the media data. For more information about setting up a remote installation server, see Chapter 4, Remote Installation from a Network Server.

  3. Only in the case of a NetWeaver installation, in the next dialog you must select the Installation Mode such as SAP Standard System, SAP Standalone Engines, etc. and the Database such as IBM DB2, MaxDB, etc. you want to deploy. In the case of a B1 or HANA installation, such a selection does not exist. See Figure 2.10, “SAP Installation Wizard: Installation Mode and Database”. Click Help for information.

    SAP Installation Wizard: Installation Mode and Database
    Figure 2.10: SAP Installation Wizard: Installation Mode and Database

    Enable Preparation for autoinstallation, if you only want to enter the installation parameters, but not perform the actual installation now. In this case, the installer will copy the product images to /data/SAP_CDs and prepare an installation environment for every product as follows:

    /data/SAP_INST/0/Instmaster
    /data/SAP_INST/1/Instmaster
    /data/SAP_INST/2/Instmaster
    ...

    If you later actually want to run the auto installation, set SAP_AUTO_INSTALL="yes" in /etc/sysconfig/sap-installation-wizard. If you then click the SAP Product Installer in the YaST Control Center to run the auto installation, all settings will be displayed and offered for optional fine-tuning (NetWeaver) or the parameters are written to the AutoYaST files in the /data/SAP_INST/number directories, where you can modify them according to your needs (HANA/B1).

  4. In case of a NetWeaver installation you now select a SAP Product. The offerings of available products depend on the media set and installation master you received from SAP; for example, see Figure 2.11, “SAP Installation Wizard: SAP Products”.

    SAP Installation Wizard: SAP Products
    Figure 2.11: SAP Installation Wizard: SAP Products
  5. For example, select SAP NetWeaver 7.4 and click Next. Now the relevant part of the SAP media will be copied to the hard drive of the machine for the following SAP installation (after copying, see the contents of /data/SAP_CDs; the layout is explained later in this chapter). This is repeated for all necessary SAP media, with some additional simple questions.

  6. You are asked to provide the Location of the SAP Medium and if additional media are needed, you can also add them afterwards; see (here you see the list of already copied or linked SAP media). Click Help for information.

    SAP Installation Wizard: Additional SAP Media
    Figure 2.12: SAP Installation Wizard: Additional SAP Media
  7. Then you can optionally copy a Supplement or 3rd-Party Medium. For more information about a Supplement Media, see Section 5.4.1, “Supplement Media”.

  8. At this point, all data (product images) required for the SAP installation is selected and copied to /data/SAP_CDs, one directory per medium, e.g.:

    /data/SAP_CDs:
    742-KERNEL-SAP-Kernel-742
    742-UKERNEL-SAP-Unicode-Kernel-742
    RDBMS-MAX-DB-LINUX_X86_64
    SAP-NetWeaver-740-SR2-Installation-Export-CD-1-3
    SAP-NetWeaver-740-SR2-Installation-Export-CD-2-3
    SAP-NetWeaver-740-SR2-Installation-Export-CD-3-3

    /data/SAP_CDs is the default directory as specified in the /etc/sysconfig/sap-installation-wizard configuration file.

  9. In the following configuration dialogs, enter the details for the SAP installation.

    First, specify the System T-Shirt-Sizing.

    SAP System Parameters: T-Shirt-Sizing
    Figure 2.13: SAP System Parameters: T-Shirt-Sizing
  10. In Figure 2.14, “SAP Virtual Network Settings”, then enable and enter the virtual network settings, if needed. For details, see the online help on the left.

    SAP Virtual Network Settings
    Figure 2.14: SAP Virtual Network Settings
  11. Now all installation data (media and settings) is available to the wizard, and the final deployment of the SAP system can take place with the SAP installer (SAPinst).

    SAP Installer (SAPinst): Defining Parameters
    Figure 2.15: SAP Installer (SAPinst): Defining Parameters

Note: Installation Progress

Depending on your machine, it takes a while until the SAPinst tool shows up.

After the SAP installer has finished, you will see a short summary of the installation data.

2.5 SLES for SAP Applications — Installation with External Profile

This installation is driven by a user-provided AutoYaST profile and there is no wizard support. This scenario is suitable for experienced users who are familiar with AutoYaST and want to deploy their own AutoYaST profiles to install SUSE Linux Enterprise Server for SAP Applications. For more information about AutoYaST profiles, see the SLES AutoYaST Guide (the AutoYaST Guide comes with the product or is available from http://documentation.suse.com/sles/11-SP4/).

In order to use a user-provided AutoYaST profile, select Install SLES for SAP Applications — Installation with External Profile from the DVD Boot Menu. Within the boot options, change the autoyast=usb:/// parameter to the location of a user-provided AutoYaST profile, or enter the location when YaST asks for it in the next dialog.

You can also reference the SAP specific pattern, the HA and WebYaST components and SAP-specific IBM Java in your AutoYaST profile and then install it during this installation scenario. As everything else, these components are not preselected and you must include this yourself in your autoyast.xml file.

2.5.1 About AutoYaST

AutoYaST is a system for installing one or more SUSE Linux systems automatically and without user intervention. AutoYaST installations are performed using an AutoYaST profile with installation and configuration data. That profile can be created using the AutoYaST configuration interface and can be provided to YaST during installation in different ways.

For more information about AutoYaST, see the SUSE Linux Enterprise Server 11 AutoYaST Guide (the AutoYaST Guide comes with the product or is available from http://documentation.suse.com/sles/11-SP4/).

2.5.2 Partitioning with AutoYaST

For standard systems find pre-defined partitioning settings in /usr/share/YaST2/include/sap-installation-wizard/. These could serve as examples if you want to create your custom partitioning scripts.

For background information on partitioning, see Chapter 3, Background Information on Partitioning.
