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:
Make sure you have the correct software. See System administrators
documentation for details.
You must have the appropriate versions of Tru64 UNIX and TCR installed
on your system to install patch kits. There are separate patch kits for
each version of the Tru64 UNIX and TCR products. The patch kits will not
install on any other version of those products. For example, the DIGITAL
UNIX 4.0D patch kit will only install on DIGITAL UNIX Version 4.0D.
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.
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:
Make sure you have met the installation prerequisites described
in
Section
4.2.
Make sure you made the patch distribution available to your system,
as described in
Section
4.3.
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.
