4    Patch Installation Instructions

This chapter provides instructions for installing manually installed patches on the Tru64 UNIX operating system and the TruCluster Software Products (TCR).

4.1    Summary of Steps for Using Patch Kits

The following list summarizes the steps necessary to install patches on your system. The referenced sections provide the full details. Compaq recommends that you familiarize yourself with these steps before attempting to install Tru64 UNIX or TCR patch kits.
    Prepare your system for patch installation (Section 4.2).

    Make the patch distribution available to your system (Section 4.3).

    Install patches mode (Section 4.4).

    Rebuild the kernel and reboot the system (Section 4.5).

4.2    Preparing to Install Patches

Before using the latest Tru64 UNIX or TCR patch distribution, make sure that your system meets the required criteria and that you perform certain preinstallation tasks, as described in the following list:

4.3    Making the Patch Distribution Available

Tru64 UNIX and TCR manually installed patches are available from your Compaq service provider. Once you have obtained the patch distributions use the following instructions to make the patch kits available to the system targeted for update:
    Ensure the installation prerequisites described in Section 4.2 are met.

    Expand the tar file to access the patch kits.

    The tar file can be expanded on any NFS mountable file system. It is recommended that the file system not exist in /usr or /var of the system that will be patched. For example:

    #/usr/sbin/mount /dev/rz3g /PatchKits

    #cd /PatchKits

    #mkdir kit8

    Copy or ftp the patch kit to /PatchKits/kit8. For example:

    #cp T64V511-C0000100-4584-Manual-20010117.tar /PatchKits/kit8

    #script untar.log

    #tar -xpvf T64V511-C0000100-4584-Manual-20010117.tar

    #^D

    View the untar.log for errors or failures untarring the file.

    Once the tar file has been expanded, make the file system containing the patch kits available to the system being patched. For example, on the system you are patching do the following:

    #/usr/sbin/mount /PatchKits/kit8@hostname /mnt
     

4.4    Installing Patches

Patch installation is performed on a patch by patch basis using installation scripts. Manually installed patches can not be installed using dupatch or setld.

Before beginning the installation, make sure that you have completed all of the preliminary steps:

The following sections provide step-by-step instructions for installing and enabling patches.

4.4.1    Choosing Single-User or Multiuser Mode

You can install patches from either single-user or multiuser modes. See Section 3.1 for information about selecting one of these modes.
 

4.4.2    Choosing which patch to install.

Now you need to choose which patch to install. Read the documents that came with the patch kit in order to determine which patches you wish to install.
 

4.4.3    Find installation script


Now look at the the untared hiearchy of the patch kit in patch_kit/$ProductName/ManualKit/ for files called *.install.sh. For example:   patch_kit/Tru64_UNIX_V5.1/ManualKit/OSFPATC0000100510.install.sh.

Each one of these files is an installation script for a patch.
 

4.4.4    Execute installation script.

Just execute the installation script. For example. patch_kit/Tru64_UNIX_V5.1/ManualKit/OSFPATC0000100510.install.sh.

4.5    Rebuilding the Kernel

The installation scripts will inform you whether a kernel rebuild and a system reboot are needed in order to make the patch become effective.
Please refer to your system documentation for instructions on how to do this.
