4 Installation on IBM POWER

This chapter describes the installation procedure of SUSE Linux Enterprise Server on IBM POWER systems.

4.1 Hardware requirements

To run SUSE Linux Enterprise Server on POWER, your hardware must meet the minimum requirements listed below.

Supported servers

Check the database of SUSE-certified hardware to make sure that your particular hardware configuration is supported. The database is available at https://www.suse.com/yessearch/Search.jsp. SUSE Linux Enterprise Server may support additional IBM POWER systems that are not listed. For the latest information, refer to the IBM Information Center for Linux at https://www.ibm.com/support/knowledgecenter/linuxonibm/liaam/liaamdistros.htm.

Memory requirements

A minimum of 1024 MB of memory is required for a minimal installation. On machines with more than two processors, add 512 MB per CPU. For remote installations via HTTP or FTP, add another 150 MB. Note that these values are only valid for the installation of the operating system—the actual memory requirement in production depends on the system's workload. For systems running the GNOME desktop environment, a minimum of 2048 MB of memory is required and 4096  MB is recommended.

Hard disk requirements

The disk requirements depend on the type of installation selected and the usage scenario. Normally, a properly working system requires more space than the installation itself. The minimum requirements are as follows.

Installation Scope

Minimum Hard Disk Requirements

Text Mode

1.5 GB

Minimal System

2.5 GB

GNOME Desktop

3 GB

All patterns

4 GB

Recommended Minimum (no Btrfs snapshots): 10 GB

Required Minimum (with Btrfs snapshots): 16 GB

Recommended Minimum (with Btrfs snapshots): 32 GB

If the root partition is smaller than 10 GB, the installer does not offer a partitioning proposal. In this case, you need to create partitions manually. To avoid this, we recommend to have 10 GB reserved for the root partition. Increase the minimum size to 16 GB if you plan to enable Btrfs snapshots on the root volume (see Chapter 10, System recovery and snapshot management with Snapper).

Before installing SUSE Linux Enterprise Server, make sure that the server has the latest firmware. For the latest firmware, visit IBM FixCentral: https://www.ibm.com/support/fixcentral/. Select your system from the Product Group list. Additional software is available from the IBM PowerLinux Tools Repository. For more information on using the IBM PowerLinux Tools Repository, see https://ibm.co/3v6LuKp.

4.2 Installing SUSE Linux Enterprise Server for POWER

The following procedure describes how to set up an installation environment. You can skip it if you already have an installation environment ready.

Procedure 4.1: Preparing an installation environment
  1. Start an SSH session to your HMC and run the vtmenu command.

  2. Select the desired POWER server and the LPAR. If a serial console session for the chosen LPAR already exists, you need to close it first using the following command:

    rmvterm -m SERVER -p LPAR
  3. Reboot the LPAR by creating a new SSH session to the HMC and running the following command:

    chsysstate -r lpar -m SERVER -o shutdown -n LPAR --immed --restart

    Note that this command causes a hard reboot of the LPAR. To perform a soft reboot and allow the running tasks to shut down properly, omit the --immed flag on the command above.

  4. When prompted, press 1 in the serial console to open the SMS Menu.

    Choose SMS Menu
  5. Select Setup Remote IPL (Initial Program Load) by pressing 2 and Enter.

    Choose Setup Remote IPL
  6. Select the NIC Adapter for accessing your TFTP server.

  7. Select the IP version to be used (for example, IPv4).

  8. Select the protocol used to access the TFTP server (for example, 1 for BOOTP).

  9. Select IP Parameters by pressing 1 and Enter.

  10. Configure the required network parameters of the LPAR, including the IP address, the network gateway, and the network mask. In the Server IP Address, specify the IP address of your TFTP server.

    Configure network parameters
  11. Use the Esc key to return to the first screen. Select the following entries in the specified order:

    • Select Boot Options

    • Select Install/Boot Device

    • Network

    • BOOTP

  12. Select the NIC adapter specified earlier, then choose:

    • Normal Mode Boot

    • Yes

  13. When the process starts, you should see a GRUB menu containing a list of images available on the TFTP server.

4.3 Installing SUSE Linux Enterprise Server

In general, installing SUSE Linux Enterprise Server on POWER is similar to a regular installation procedure.

Procedure 4.2: SUSE Linux Enterprise Server installation
  1. In the first two steps, you are prompted to choose the desired language and keyboard and to read and agree to the product's license agreement.

  2. Next, choose the desired product registration method and complete the registration. If you register the system using the SUSE Customer Center, you are prompted to enable update repositories. Press Yes.

    Registering the product
  3. To install any modules or extensions, select each one using the arrow keys and pressing Space. Depending on what extensions and modules you select, you may be prompted to import GnuPG keys for the associated repositories.

    Selecting extensions and modules
  4. Install the desired add-on products. If you choose to install an add-on, you need to specify the installation source for it.

    Installing add-on products
  5. Specify a partition scheme for your installation. To accept the default proposal, press Next or press AltN.

    Specifying a partition scheme
  6. Choose the system role suitable for your particular scenario.

    Choosing a system role
  7. The next few screens allow you to specify the appropriate time zone, and create a user. If you choose not to create a user, you are prompted to specify a root password.

  8. In the installation summary screen, make sure the SSH service is enabled and open an SSH port. To do this, press Change, go to the Basic Firewall and SSH Configuration screen, and enable the appropriate options. Press OK.

    Configuring SSH settings
  9. Confirm the installation configuration, and press Install to start the installation process.
