HP Tru64 UNIX Version 5.1B-2 and Higher Patch Kit Installation Instructions (March 2009)

3 Patch Installation and Removal Instructions
This chapter provides instructions for installing and removing patches from the Tru64 UNIX
operating system and the TruCluster software products. Although the descriptions and examples
in this chapter reflect the installation and removal steps of Release Patch Kits, the steps are
basically the same for dupatch-based CSP and ERP kits.
“Rolling Upgrade” describes the procedure for patching a TruCluster Server Version 5.0A or
higher cluster using the rolling upgrade function. If you are patching your system with that
process, follow the steps described there. You will be returned to this chapter when it is time to
run dupatch.
If you have not yet created your cluster, follow the steps in “Patching a System Prior to Creating
a Cluster”.
The -l of the setld command is disabled for patch subsets.
Before You Begin the Installation
Before beginning the installation, make sure that you have completed all of the following
preliminary steps:
• Make sure you have the correct software
You must have the appropriate versions of Tru64 UNIX and TruCluster software installed
on your system to install patch kits. There are separate patch kits for each version of the
Tru64 UNIX and TruCluster software products. The patch kits will not install on any other
version of those products. For example, a Tru64 UNIX 5.1B patch kit will only install on
Tru64 UNIX Version 5.1B.
• Back up your system
It is recommended that you backup your /, /usr, and /var file systems prior to installing
patches or baselining your system.
• Make sure you have enough storage space
Refer to the Patch Summary and Release Notes for the required storage space.
• Make the patch distribution available to your system, as described in “Expanding the Patch
Kit Tar File”.
• Load any new patch tools, as described in “Invoking dupatch and Installing New Patch
Tools”.
• Perform the patch preinstallation check, as described in “Performing a Patch Preinstallation
Check”.
• Set a system patch baseline, if needed, as described in “Creating a Baseline”.
• Review the list of issues and restrictions in “General Issues and Restrictions” and in the
Patch Summary and Release Notes document that comes with your patch kit.
The following sections provide step-by-step instructions for installing and enabling patches.
Expanding the Patch Kit Tar File
If you are using patch tar files obtained via the Internet (see “Patch Process Resources”), you
must expand the tar file to access the patch kits. The tar file can be expanded on any mountable
file system. The following list describes procedure:
1. Mount the file system and create a directory.
