About This Manual

This manual provides instructions for installing and removing patches that are provided by Compaq Computer Corporation in its Tru64 UNIX and TruCluster software products patch kits. It also describes baselining techniques and provides other information for working with patches.

The information provided here deals with patches installed on Versions 4.0D and higher and 5.0 and higher, including both official and customer-specific (CSP) patches. The differences in dealing with the different product versions and patch-kit types are minimal; this manual alerts you to those differences during process discussions and step-by-step instructions.

The process for installing and removing patches using the rolling upgrade procedure, introduced in Version 5.0A release of the TruCluster Server software, is discussed in Chapter 5.

For information about individual patches, see the Patch Summary and Release Notes document for the kit you are installing.

Note

In most instances, this manual uses the name Tru64 UNIX for all versions of the operating system, including those that were originally released as DIGITAL UNIX.

In general, the terms TruCluster software products and TCR are used throughout this manual to refer to all releases of Compaq's TruCluster products.

Audience

This manual is for those who install and remove patch kits and manage patches after they are installed.

Organization

The first two chapters describe the concepts of the patching process and provide an overview of the patch management utility, dupatch. Chapter 3 lists issues and restrictions you should be aware of before you begin to work with the patch kits following the step-by-step procedures in Chapter 4.

This manual is organized as follows:

Chapter 1 Provides an overview of the concepts and features of the patch kits.
Chapter 2 Introduces the dupatch utility and describes its features.
Chapter 3 Provides information you must be aware of when installing and removing patches.
Chapter 4 Describes the procedures for installing and removing patches.
Chapter 5 Describes the rolling upgrade process for patching a cluster running TruCluster Server Version 5.0A or higher while the cluster is in operation. This process is also used for upgrading to a new version of the TruCluster Server software or for doing an upgrade and a patch together.
Appendix B Provides examples of a typical patch installation, a TruCluster patch installation in a rolling upgrade, a baselining process, and a patch removal process.
Appendix A Describes error messages you might see while installing, removing, or maintaining patches.
Appendix C Provides information about using the dupatch command-line interface and documents the dupatch(8) reference page.
Appendix D Provides Tru64 UNIX system upgrade information.

Conventions

This guide uses the following conventions:

file

Italic (slanted) type indicates variable values, placeholders, and function argument names.

[Ctrl/x]

This symbol indicates that you hold down the first named key while pressing the key or mouse button that follows the slash. In examples, this key combination is enclosed in a box (for example, [Ctrl/C] ).

% cat

Boldface type in interactive examples indicates typed user input.

device names

Operating system versions before Version 5.0 use different names than those of Version 5.0 and higher. In general, this manual uses the Version 5.0 names. For example, where a partition name is represented by /dev/disk/dsk3g, the Version 4.0n name might be /dev/rz3g.

This symbol is used in output examples to replace redundant information. This is information you would see on your terminal screen or in a log file created by dupatch, but is not particularly useful in the examples in this manual.
