3 Installation on IBM POWER #
This chapter describes the procedure for preparing the installation of SUSE® Linux Enterprise Server on IBM POWER systems.
3.1 Requisitos #
Uma instalação padrão requer, no mínimo, 512 MB de RAM. A instalação de um sistema padrão com a área de trabalho do GNOME requer pelo menos 3,5 GB de espaço livre no disco rígido; a instalação completa requer aproximadamente 8,5 GB.
3.1.1 Requisitos de hardware #
O sistema operacional SUSE® Linux Enterprise Server pode ser operado em servidores IBM POWER8. Para orientá-lo durante a fase de planejamento, os requisitos mínimos são apresentados aqui.
Para ter certeza de que determinada configuração do computador vai funcionar, verifique o banco de dados do hardware certificado pelo SUSE. Há uma lista de hardwares certificados em http://www.suse.com/yessearch/Search.jsp.
O SUSE Linux Enterprise Server pode suportar outros sistemas IBM POWER que não estejam na lista a seguir. Para obter as informações mais recentes, consulte o Centro de Informações da IBM para Linux em http://www.ibm.com/support/knowledgecenter/linuxonibm/liaam/liaamdistros.htm.
Encontre um firmware atualizado em IBM FixCentral (http://www.ibm.com/support/fixcentral/). Selecione seu sistema na lista de grupos de produtos. O software adicional está disponível no IBM PowerLinux Tools Repository. O IBM Tools Repository também é chamado de Repositório YUM. Para obter mais informações sobre como usar o IBM PowerLinux Tools Repository, consulte https://ibm.biz/Bdxn3N.
3.1.1.1 Servidores IBM POWER8 baseados em processador #
Todos os servidores POWER8 compatíveis com PowerKVM são suportados.
8247-21L (IBM Power® System S120L)
8247-22L (IBM Power System S220L)
8284-22A (IBM Power System S2200)
8286-41A (IBM Power System S1400)
8286-42A (IBM Power System S2400)
3.2 Preparation #
This section describes the preparatory steps that must be taken before the actual installation of SUSE Linux Enterprise Server. The installation procedure depends on the system used. The following methods are supported:
If SUSE® Linux Enterprise Server needs to be installed on several systems or partitions, it is recommended you create a network installation source. The same source can also be used for the concurrent installation on several partitions or several systems. The configuration of a network installation source is described in Seção 8.1, “Configurando um servidor de instalação usando YaST”.
3.2.1 Installation on Servers with IBM PowerKVM using Kimchi #
This section covers the preparatory steps for installing on IBM PowerLinux systems with PowerKVM. It explains the installation from an ISO image with the Kimchi Web interface. Kimchi is a tool for administrating IBM PowerKVM.
This section assumes you have PowerKVM running on your IBM PowerLinux server. If PowerKVM is not preinstalled see “Configuring IBM PowerKVM on Power Systems” at http://www.ibm.com/support/knowledgecenter/linuxonibm/liabp/liabpkickoff.htm for installing and setting up PowerKVM.
3.2.1.1 Creating a SUSE Linux Enterprise Server Template with Kimchi #
Templates are the installation source for PowerKVM guests. You can create a template, edit an existing template, or clone a template. To clone a template from an existing guest, that guest must be deactivated.
In the Web browser, enter the URL of the PowerLinux server where PowerKVM is running, for example
https://POWERLINUX_IP:8001
(replace POWERLINUX_IP with the IP address of your system).Click the
tab to activate the page.Click the green plus sign (
) to create the SUSE Linux Enterprise Server template.On the
dialog, select from the following options:Select to scan storage pools for installation ISO images available on the system.
Select to specify a path to a local image file.
Select to specify a remote location for an installation ISO image.
Select the ISO file that you want to use to create a guest and click
.To configure the newly created template, click
› , and change the default values as required by your workload.
For more information, see “Setting up a template using Kimchi” at http://www.ibm.com/support/knowledgecenter/linuxonibm/liabp/liabpkimchitemplate.htm.
3.2.1.2 Installing SUSE Linux Enterprise Server as a Guest with Kimchi #
In the Web browser, enter the URL of the PowerLinux server where PowerKVM is running, for example
https://POWERLINUX_IP:8001
(replace POWERLINUX_IP with the IP address of your system).Click the
tab to activate the page.Click the green plus sign (
) to create the SUSE Linux Enterprise Server guest.Enter a
for the SUSE Linux Enterprise Server guest.Choose the SUSE Linux Enterprise Server template created in Seção 3.2.1.1, “Creating a SUSE Linux Enterprise Server Template with Kimchi” and click .
After the guest is created, it is ready to be started. Click the red power button to start the SUSE Linux Enterprise Server guest. Alternatively, select
› .Click Seção 10.3.1.2, “Conectando-se ao programa de instalação”.
› , and connect your VNC viewer to the installation process as outlined in
To create multiple guests of a similar type, select
from the menu of an existing guest.Now you can continue with the default installation via VNC as described in Seção 6.3, “Etapas da instalação”.
3.2.2
Installation on Servers with IBM PowerKVM using
virt-install
#
Alternatively to installing with Kimchi, use the
virt-install
command line tool to install on servers with
IBM PowerKVM. This is especially useful you need to install multiple
virtual machines on IBM PowerLinux Server
systems. virt-install
allows many installation scenarios;
in the following a remote installation scenario via VNC and PXE boot is
outlined. For more information about virt-install
, see
Section 9.2, “Installing from the Command Line with virt-install
”.
Prepare a repository with the installation sources and PXE boot enabled target system as described in Seção 10.1.3, “Instalação remota por VNC: inicialização PXE e Wake on LAN”.
On the command line, enter something similar as follows (adjust the options according to your needs and matching your hardware):
virt-install --name server_sle12 --memory 4096 --vcpus=2 --pxe \ --graphics vnc --os-variant sles11 \ --disk pool=default,size=3000,format=qcow2,allocation=1G,bus=virtio \ -w mac=MAC_ADDRESS,model=spapr-vlan
It will use VNC graphics, and it will automatically launch the graphical client. Complete the installation as described in Seção 6.3, “Etapas da instalação”.
3.2.3 Installation in a Partition Using IVM #
This guide helps you install SUSE Linux Enterprise Server on a Power Systems server partition using the Integrated Virtualization Manager (IVM) Web interface. Before starting the installation, make sure the following requirements are met:
the Linux on Power system is powered on
the Virtual I/O server is installed
the IVM is initially configured
Open a Web browser window, and connect using the HTTP or HTTPS protocol to the IP address that was assigned to the IVM during the installation process (for example, https://IP_ADDRESS). The Welcome window is displayed.
Log in as the user

, providing the password that you defined during the installation process. The IVM interface is displayed.Select
.Click
to provide Ethernet connectivity among the partitions.When the Virtual Ethernet is initialized, click Apply.
If your installation requires external networking, create a virtual Ethernet bridge.
Select the
tab.Select the physical adapter to bridge and proceed with

Next, create a partition, following these steps:
In the IVM Web interface, click
› .Enter a name for the partition. To advance to the next step, click
on this and the following steps.Specify memory for your partition. If you have created a shared memory pool, your partitions can share memory. Otherwise, select
.Specify the number of processors and the processing mode for the partition.
Specify a virtual Ethernet for the partition. If you do not want to configure an adapter, select
for the virtual Ethernet.Create a new virtual disk or assign existing virtual disks and physical volumes that are not currently assigned to a partition.
Verify the
