Installation and Setup

This chapter describes how to install and set up a SUSE Linux OS on Hitachi

Compute Blade.

Restrictions

Setting up SUSE Linux

2-2 Installation and Setup


Related document

You are required to refer to the following documents to set up an LPAR manager, install a SUSE Linux OS and a SUSE Linux Enterprise Server driver,

and so on.

- Hitachi Compute Blade 2500 Series Logical partitioning manager User Guide

- HITACHI Gigabit Fibre Channel Adapter USER’S GUIDE (SUSE Linux Enterprise Server driver Edition)

Restrictions

There are the following restrictions on LPARs with a SUSE Linux OS.

- Performing a migration execution in Shutdown mode or Concurrent Maintenance mode to LPARs with the subject OS.

- Performing an N+M Cold Standby execution to an LPAR manager where

LPARs with the subject OS exist.



Setting up SUSE Linux

The steps for setting up a SUSE Linux OS are as follows:

- LPAR manager settings

- LPAR configuration

- OS installation

- OS option settings

- Application of OS patches

Note that, for the step “OS option settings”, the procedure for SUSE Linux Enterprise Server for SAP Applications 11 SP3 and that for SUSE Linux Enterprise Server for SAP Applications 12 are respectively described below in

this section: “Setting up SUSE Linux”.

LPAR manager settings

See “Starting and Stopping LPAR manager” in the Hitachi Compute Blade 2500 Series Logical partitioning manager User Guide.

Then, enable the “Performance tuning options” parameter and confirm the

restrictions on “Performance tuning options”, seeing “Performance tuning options” in “Setting Processors and Memory Functionality” in the Hitachi Compute Blade 2500 Series Logical partitioning manager User Guide.

LPAR configuration

See “Creating LPARs” in “Creating LPARs” in the Hitachi Compute Blade 2500 Series Logical partitioning manager User Guide.

Then, see “Changing the configuration of an LPAR” in “Creating LPARs” in the Hitachi Compute Blade 2500 Series Logical partitioning manager User Guide.



OS installation

Having the LPAR recognize the Driver & Utility CD for SUSE Linux

You are able to select one way to have the LPAR recognize the Driver & Utility CD for SUSE Linux from the following two ways:

- Having the remote console recognize the ISO image of the Driver & Utility CD

Start the remote console. Next, push the “Remote CD/DVD” button on the

remote console and then have the remote console recognize the ISO image of the Driver & Utility CD in a CD/DVD drive.

- Connecting a CD/DVD drive with the Driver & Utility CD to a USB port

Connect the USB connector of a CD/DVD drive direct to a USB port on a server blade and then insert the Driver & Utility CD to the CD/DVD drive.

Changing the boot order and setting the UEFI driver

Make sure that you configure two paths so that an LU in which to install the

OS can be accessed through the two paths, in advance. See “Setting the boot order for LPARs from the Web console” in “Creating LPARs” in the Hitachi Compute Blade 2500 Series Logical partitioning manager User Guide.

Saving the LPAR manager configuration

See “Saving the LPAR manager” in “Creating LPARs” in the Hitachi Compute

Blade 2500 Series Logical partitioning manager User Guide.



Installing OS and SUSE Linux Enterprise Server driver

Once the message "Connecting Boot Devices and Adapters --" is displayed on the remote console after activating the LPAR, you are required to push the F1 key. We recommend that you read “Install driver on Linux” in the HITACHI Gigabit Fibre

Channel Adapter USER’S GUIDE (SUSE Linux Enterprise Server driver Edition) in advance. Also, you can move on to the next step smoothly by starting the remote console in advance.

(1) Activate the LPAR and then enlarge the remote console screen.

(2) From the step required to push the F1 key in “Install driver to SAN with Hitachi

Gigabit Fibre Channel Adapter” in “Install driver on Linux” in the HITACHI Gigabit Fibre Channel Adapter USER’S GUIDE (SUSE Linux Enterprise Server driver Edition), follow the procedure in the chapter.

(3) Install LAN drivers, seeing in the Hitachi Compute Blade 2500 Intel LAN Driver Instruction Manual for SUSE Linux Enterprise Server.
