2.3 Preparing an Installation on IBM POWER JS20/JS21/JS22 Blades

This section describes the preparatory steps for the installation of SUSE® Linux Enterprise Server on JS20/JS21/JS22 Blades. It covers installation using the CD-ROM drive of the BladeCenter and using the network.

2.3.1 Creating a Network Installation Source

Create a network installation source if SUSE Linux Enterprise Server should be installed over a number of partitions. This provides the advantage that no CDs need to be changed during installation. The same source can also be used for the concurrent installation of various systems. Configuration of a network installation source is described in Section 4.2.1, Setting Up an Installation Server Using YaST, (↑ Installation and Administration ).

2.3.2 Hard Disk Storage Space

Ensure that enough hard disk storage space is available for the installation of SUSE Linux Enterprise Server. It is recommended to use a dedicated hard disk.

2.3.3 Notes and Information

2.3.4 Preparing the System for Boot

Preparing to Boot from the CD-ROM Drive

Perform the steps described in this section if an installation from CD-ROM is desired.

Assign the CD-ROM drive to the Blade chosen for installation by connecting with a Web browser to a BladeCenter Management Module then logging in. After login, select the function Remote Control in the menu Blade Tasks then activate Start Remote Control. Assign the CD-ROM drive to the desired blade in the menu Change Media Tray Owner of the new window.

Then set up the CD-ROM drive as a boot device. Do this by selecting Blade Tasks then Configuration while in the BladeCenter Management Module. Then select the JS20/JS21/JS22 Blade in the section Boot Sequence. Set the entry for 1st Device on the page for Blade Boot Sequence to CDROM.

Put CD 1 in the CD-ROM drive and restart the blade.

Preparing to Boot from the Network

Perform the steps as described in this section if an installation over the network is desired.

Connect to the BladeCenter Management Module using a Web browser and log in. Set the boot device to the network by accessing the Configuration menu from the Blade Tasks page. Then select the JS20/JS21/JS22 Blade in the section Boot Sequence and set 1st Boot Device to Network — BOOTP on Blade Boot Sequence.

Rebooting and Connecting to the Console of the JS20/JS21/JS22 Blade

Reboot the JS20/JS21/JS22 Blade from the item Power/Restart of the Blade Tasks menu in the BladeCenter Management Module. A table appears, showing the power status of the blades in the Pwr column. Mark the check box of the desired blade and restart it with Power On Blade.

Connect to the BladeCenter with the command telnet bladecenter and log in.

The command env -T system:blade[bay number] determines for which JS20/JS21/JS22 Blade the subsequent commands are intended. The blades installed in the BladeCenter are listed by calling list -l 3.

                sp
        blade[13]
                sp
        mt
system> 

The command target is then determined. To work, for example, with blade number 9, enter env -T system:blade[9]. Connect with the console of the JS20/JS21/JS22 Blade over Serial over LAN (SOL) with the command console.

system> env -T system:blade[9]
OK
system:blade[9]> console

Starting the Installation

The SUSE Linux Enterprise Server boot loader starts after the system check has completed.

Config file read, 149 bytes


  Welcome to SuSE Linux (SLES-9)!

  Use  "install"     to boot the pSeries 64bit kernel
  Use  "install32"   to boot the 32bit RS/6000 kernel

  You can pass the option "noinitrd"  to skip the installer.
  Example: install noinitrd root=/dev/sda4

Welcome to yaboot version 1.3.11.SuSE
Enter "help" to get some basic usage information
boot:

Select install from the menu and press Enter.

HINT: Textmode Installation Required

Installations IBM POWER JS20/JS21/JS22 require textmode. Initiate the installation at the kernel boot prompt with the boot parameter textmode=1. During the system reboot specify linux 3 to start the system runlevel 3, which is the running system without the graphical user interface.

Serial Over LAN (SOL) installations are not affected by this limitation.

In the case of an installation over VNC, append the parameters vnc=1 and vncpassword=password to the command line for the kernel (install).

Additional Steps

Proceed as described in Section 3.0, Installation with YaST, (↑ Installation and Administration ) to begin installing the software with linuxrc and YaST.
