Before You Begin the Installation

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.
