Installation Overview

This chapter describes the type of instructions provided in this guide and the hardware and software requirements for installing AFS(R).

Before beginning the installation of your cell's first machine, read this chapter and the material from the IBM AFS Administration Guide listed in Recommended Reading List. It is also best to read through Installing the First AFS Machine before beginning the installation, so that you understand the overall scope of the installation procedure. Similarly, before installing additional server or client machines it is best to read through Installing Additional Server Machines and Installing Additional Client Machines.

If you are already running a version of AFS, consult the upgrade instructions in the IBM AFS Release Notes or contact the AFS Product Support group before proceeding with the installation.

The Procedures Described in this Guide

This guide describes two types of installation procedures: initial procedures (such as installing the first AFS machine or incorporating AFS into the kernel) and as-needed procedures (such as installing additional server machines or client machines).

Required Initial Procedures

You must perform the following basic procedures to start using AFS.

Incorporating AFS Into the Kernel

You must incorporate AFS modifications into the kernel of every AFS file server and client machine. Depending on the operating system, you either use a program for dynamic kernel loading, build a new static kernel, or can choose between the two. For your convenience, the instructions for incorporating AFS into the kernel appear in full in every chapter where you need to use them.

Installing the First AFS Machine

You install the first AFS machine in your cell to function as both an AFS server and client machine. You can disable the client functionality after completing the installation, if you wish.

The first server machine in a cell performs several functions:

After you install server and client functionality, you complete other procedures specific to the first machine, including setting up the top levels of your cell's AFS filespace.

As-needed Procedures

Upgrading the Operating System

Upgrading the operating system requires you to take several steps to protect data and AFS-modified binaries from being lost or overwritten. For guidelines, see About Upgrading the Operating System.

Installing Additional File Server Machines

See Installing an Additional File Server Machine.

Configuring or Decommissioning Database Server Machines

See Installing Database Server Functionality and Removing Database Server Functionality.

Installing Additional AFS Client Machines

See Installing Additional Client Machines.

Building AFS from Source Code

See Appendix A, Building AFS from Source Code.

Recommended Reading List

To develop the best understanding of the overall scope of an installation procedure, read through the entire chapter or section that describes it before performing any actions.

In addition, familiarity with some basic AFS concepts can make the installation more efficient, because you understand better the purpose of the steps. The following is a prioritized list of material to read before installing the first AFS machine. At minimum, read the first chapter of the IBM AFS Administration Guide. Then continue your reading in the indicated order, as extensively as you can. It is more important at this point to read the conceptual material in each section than the instructions.

You must comply with the following requirements to install AFS successfully.

Login Identity

Log into the machine you are installing as the local superuser root. When instructed, also authenticate with AFS as the administrative user admin.

General Requirements

File Server Machine Requirements

Client Machine Requirements

Supported System Types

The IBM AFS Release Notes for each AFS release list the supported system types. Support for subsequent revisions of an operating system often becomes available between AFS releases. The AFS Product Support group can provide details.

It is the goal of the AFS Development and Product Support groups to support AFS on a wide range of popular system types. Furthermore, each time an operating system vendor releases a new general availability version of a supported operating system, it is a goal to certify and support AFS on it within a short time. Support can be delayed a bit longer if it is necessary to generate completely new binaries.

It is not always possible to support AFS on every intermediate version of an operating system or for certain processor types. In some cases, platform limitations make certain AFS functionality (such as file server or NFS/AFS translator functionality) unavailable on one or more platforms. For a list of limitations, see the IBM AFS Release Notes or ask the AFS Product Support group.

About Upgrading the Operating System

Whenever you upgrade an AFS machine to a different operating system, you must take several actions to maintain proper AFS functionality. These actions include, but are not necessarily limited to, the following.

The AFS Binary Distribution

The AFS Binary Distribution includes a separate CD-ROM for each supported system type, containing all AFS binaries and files for both server and client machines. The instructions in this guide specify when to mount the CD-ROM and which files or directories to copy to the local disk or into an AFS volume.

How to Continue

If you are installing the first AFS machine in your cell, proceed to Installing the First AFS Machine.

If you are installing an additional file server machine, or configuring or decommissioning a database server machine, proceed to Installing Additional Server Machines.

If you are installing an additional client machine, proceed to Installing Additional Client Machines.
