Installation Overview

Installation Overview

This book contains reference, installation, configuration, and administration information for the IBM ServeRAID-3H adapter, ServeRAID-3L adapter, and ServeRAID controllers.
In addition to this book, you might need to refer to your IBM server documentation for Safety information, connector locations, and for adapter and hard disk drive installation instructions.

The information that you will need to install or configure your IBM ServeRAID subsystem depends on the type of ServeRAID adapter or controller you are using and your familiarity with RAID technology.

A typical installation and configuration of an IBM ServeRAID subsystem consists of the following steps:

1.  Learn about RAID technology.

    The 'Understanding RAID Technology' section in this chapter contains general information about RAID technology.
    If you already are familiar with the IBM implementation of RAID technology, you might want to start your installation with step 2.

2.  Install the ServeRAID-3H or ServeRAID-3L adapter.

    Chapter 2, 'Installing and Cabling the Adapter' provides information about the standard features of the ServeRAID-3H  and ServeRAID-3L adapters, and installation and cabling instructions for the adapters.
    You will not need the information in this chapter if you are using a ServeRAID controller on an  IBM Netfinity or PC Server system board.

3.  Use the ServeRAID Configuration Programs to configure your disk arrays.

    Chapter 3, 'Using the Configuration Programs' explains how to use the IBM ServeRAID Configuration Program and the IBM  ServeRAID Mini-Configuration Program.
    You can refer to the information in this chapter or the online information in the configuration program  when configuring one or more devices attached to a ServeRAID adapter or controller.

     -Attention- The default setting for the stripe-unit size is 8 KB.  If you want to use a different setting, be sure to change the stripe-unit size before you store data in the  logical drives.
    After you store data in the drives, you cannot change the stripe-unit size without destroying data in the  logical drives. (See 'Interleave Depth and Stripe-Unit Size' and 'Using the Menu Bar' for more information.)

   •  If you are configuring a ServeRAID-3H Ultra2 SCSI Adapter or a ServeRAID-3L Ultra2 SCSI Adapter,
      see Chapter 3, 'Using the Configuration Programs' for instructions.
   •  If you are configuring an IBM ServeRAID controller that came as a standard feature on an IBM Netfinity  or PC Server system board, see the installation instructions and CDs provided with your server for information  about starting the configuration programs for the server.

4.  Install your operating system, ServeRAID device drivers, and ServeRAID utility programs.

    You can skip this step if you are installing multiple ServeRAID adapters and you already installed your operating system  and the most current versions of the ServeRAID device drivers and utility programs.

   •  To install these files for a ServeRAID-3H Ultra2 SCSI Adapter or a ServeRAID-3L Ultra2 SCSI Adapter, see the  information provided with your operating system and Chapter 4, 'Installing Device Drivers and Utility Programs'  for instructions.
   •  To install these files for an IBM ServeRAID controller that came as a standard feature on an IBM Netfinity or  PC Server system board, see the installation instructions and CDs provided with your server for instructions.
      After you install the device drivers and utility programs, refer to  Chapter 5, 'Starting and Using the Utility Programs'.
