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

General Issues and Restrictions
This section provides information you must be aware of when installing or removing patches.
Be sure to check the Patch Summary and Release Notes document of the kit you are installing for
any issues and restrictions that pertain to that installation.
When Single-User Mode Is Recommended
Although you can install patches in multi-user mode, we recommend that you bring down your
system to single-user mode when installing patches that affect the operation of the Tru64 UNIX
operating system or the product you are patching. If your system must remain in multi-user
mode, apply the patches when the system is as lightly loaded as possible.
There are no restrictions on performing patch selection and preinstallation checking in multi-user
mode. Patch removals can only be done in single-user mode.
Use Clean Directory for Each Patch Kit
When installing a patch kit downloaded from the Web, untar the file in a clean directory; that
is, one that does not contain files from a previous patch kit. A failure to do this can have adverse
consequences when installing the new kit.
Patching a System Prior to Creating a Cluster
Patching your system before creating your cluster can save you time, although if you do so, be
aware that you cannot then remove the patch kit.
The following steps describe how to patch your system before creating a cluster:
1. Install and configure the Tru64 UNIX operating system.
2. Use the setld command to install the TruCluster software kit. If the TruCluster software
kit is not loaded before the patch operation, patches for TruCluster software will not be
loaded.
3. Patch the system.
4. Use the clu_create command to create the single-member cluster.
See the Tru64 UNIX Installation Guide for information about installing the operating system and
the TruCluster Cluster Installation manual for information about creating your cluster.
RIS and DMS Unsupported for Patch Installation
Remote Installation Services (RIS) and Dataless Management Services (DMS) installations of
patches are not supported. However, the patch kit installation mechanism does support network
installation via NFS.
Direct setld Installation and Removal of Patch Subsets Is Not Allowed
You can install and remove Tru64 UNIX and TruCluster software patches only through dupatch.
You cannot directly install or reinstall the patch subsets with setld. This ensures that patch
tracking and management are not compromised.
Limitation for /var/adm/patch/backup Directory Handling
The patch management utility assumes there is one /var/adm/patch/backup directory per
system. It does not handle placement of archived original files for multiple systems in one
directory.
Do Not Enter Ctrl/c During Installation Phase
Do not enter a Ctrl/c command during the installation phase of the patch kit.
