Description: Patch Kit Installation Instructions: Tru64 UNIX Patch Kits

# About This Manual

This manual provides instructions for installing and removing patches that are provided by Hewlett-Packard Company 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 applies to Release Patch Kits, Customer-Specific Patch Kits (CSPs), and Early Release Patch Kits (ERPs) installed on Versions 4.0F and higher. 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.

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

## 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 system 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 software software or for doing an upgrade and a patch together.
Chapter 6 | Describes the no-roll patch process, which provides a way to apply patches to a cluster quickly in order to minimize downtime and reduce the number of reboots required.
Appendix A | Describes error messages you might see while installing, removing, or maintaining patches.
Appendix B | Provides examples of a typical patch installation, a TruCluster software patch installation in a rolling upgrade, a baselining process, and a patch removal process.
Appendix C | Provides information about using the `dupatch` command-line interface and documents the `dupatch`(8) reference page.

## 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.
