About This Book

The AIX 5L Version 5.2 Operating System Installation: Getting Started guide provides system administrators with information about how to install and configure the AIX operating system on a standalone system using a CD–ROM device. The two methods described in this book are the new and complete overwrite installation method and the migration installation method. This publication is also available on the ”Hypertext Library for AIX 5.1”

CD-ROM that is shipped with the operating system.

For complete conceptual and task information about installing AIX, see the AIX 5L Version

5.2 Installation Guide and Reference.

Who Should Use This Book

This book provides system administrators with information about performing an AIX installation using the CD–ROM device. The two methods described in this book are the new and complete overwrite installation method and the migration installation method.

Highlighting

The following highlighting conventions are used in this book:

Bold

Italics

Monospace

Identifies commands, subroutines, keywords, files, structures, directories, and other items whose names are predefined by the system. Also identifies graphical objects such as buttons, labels, and icons that the user selects.

Identifies parameters whose actual names or values are to be supplied by the user.

Identifies examples of specific data values, examples of text similar to what you might see displayed, examples of portions of program code similar to what you might write as a programmer, messages from the system, or information you should actually type.

Case–Sensitivity in AIX

Everything in the AIX operating system is case–sensitive, which means that it distinguishes between uppercase and lowercase letters. For example, you can use the ls command to list files. If you type LS, the system responds that the command is ”not found.” Likewise, FILEA,

FiLea, and filea are three distinct file names, even if they reside in the same directory. To avoid causing undesirable actions to be performed, always ensure that you use the correct case.

Chapter 1. Introduction to Base Operating System

Installation

This guide provides an overview of the necessary steps to complete an installation of the

AIX 5.2 Base Operating System (BOS).

The BOS installation program first restores the run–time bos image, then installs the appropriate filesets, depending on whether you are installing from a graphical or an ASCII system. The installation program automatically installs required message filesets and devices filesets, according to the language you choose and the hardware configuration of the installed machine.

You can use the following methods for installing AIX:

New and Complete Overwrite

This method installs AIX 5.2 on a new machine or completely overwrites any BOS version that exists on your system.

Migration This method upgrades from AIX 4.2 or later versions of the BOS to AIX 5.2.

A migration installation preserves most file systems, including the root volume group, logical volumes, and system configuration files. It overwrites the /tmp file system.

Preservation This method replaces an earlier version of the BOS but retains the root volume group, the user–created logical volumes, and the /home file system. It overwrites the /usr, var, tmp, and / (root) file systems. Product

(application) files and configuration data are lost. For information about preservation installation, see the AIX 5L Version 5.2 Installation Guide and

Reference.

The table below shows the differences in the installation steps between the new and complete ovewrite installation and the migration methods.

Electronic License Agreements

AIX 5.2 ships with software license agreements and are viewable electronically. If a product has an electronic license agreement, it must be accepted before software installation can continue. In the case of initial BOS installation, you can view and accept license agreements in a license agreement dialog after the installation has occurred, but before the system is

available for use as part of Configuration Assistant (graphical consoles) or Installation

Assistant (ASCII consoles).

The Base Operating System (BOS) has a license agreement, but not all software packages do. When you agree to the license agreement for BOS installation, you are also accepting all license agreements for any software installed automatically with the BOS. Some software, such as the GNOME or KDE desktops, can be optionally installed during BOS installation; the appropriate licensing information for such software is displayed separately.

For more information on license manipulation, see the AIX 5L Version 5.2 Installation Guide and Reference.

AIX 5L Release Notes.

2. Make sure your hardware installation is complete, including all external devices. See the documentation that came with your system unit for installation instructions.

3. If the system is currently installed, make a backup copy of your system software and data if you are installing over an existing version of AIX. For instructions on how to create a system backup, refer to the Creating System Backups section in the AIX 5L Version


4. If your system needs to communicate with other systems and access their resources, make sure you have the following information before proceeding with installation:

Network Interface Adapter

Host Name

IP Address

Network Mask

Nameserver

Domain Name

Chapter 3. Migration Installation

Use the following steps to migrate your current version of the operating system to AIX 5.2.

•


•

Step 2. Boot from the AIX Product CD on page 3-2

•

Step 3. Verify Migration Installation Settings and Begin Installation on page 3-2

•

Step 4. Verify System Configuration after Installation on page 3-3

For more information on Migration Installation, refer to the Migration Installation section in the AIX 5L Version 5.2 Installation Guide and Reference.

Refer to the Network Installation Management (NIM) section in the AIX 5L Version 5.2

Installation Guide and Reference, if you are performing a network installation of AIX.

Attention: This procedure requires shutting down and reinstalling the base operating system. Whenever you reinstall any operating system, schedule your downtime when it least impacts your workload to protect yourself from a possible loss of data or functionality.

Before you perform a migration installation, ensure you have reliable backups of your data and any customized applications or volume groups. For instructions on how to create a system backup, refer to Creating System Backups in the AIX 5L Version 5.2 Installation

Guide and Reference.


1. Ensure that the root user has a primary authentication method of SYSTEM. You can check this condition by typing the following command:

# lsuser –a auth1 root If needed, change the value by typing the following command:

# chuser auth1=SYSTEM root

2. Before you begin the installation, other users who have access to your system must be logged off.

3. Verify that your applications will run on AIX 5.2. Also, check if your applications are binary–compatible with AIX 5.2. If your system is an application server, verify that there are no licensing issues. Refer to your application documentation or provider to verify on which levels of AIX your applications are supported and licensed.

4. Verify that all currently installed software is correctly entered in the Software Vital

Product Database (SWVPD), by using the lppchk command. To verify that all filesets have all required requisites and are completely installed, type the following:

# lppchk –v

5. Check that your hardware microcode is up–to–date.

6. All requisite hardware, including any external devices (such as tape drives or

CD/DVD–ROM drives), must be physically connected and powered on. If you need further information, refer to the hardware documentation that accompanied your system.

7. Use the errpt command to generate an error report from entries in the system error log.

To display a complete detailed report, type the following:

# errpt –a

8. There must be adequate disk space and memory available. AIX 5.2 requires 128 MB of memory and 2.2 GB of physical disk space. For additional release information, see the

AIX 5.2 Release Notes.
