Installation and Upgrade Guide

NOTE: Unless you have specific reasons to do otherwise, HP recommends that you accept the
defaults and install all OpenVMS options. OpenVMS and layered products have various
dependencies on many of these options. Even if you think you do not need certain options, some
OpenVMS or layered product operations might not work correctly if other OpenVMS options
are not installed.
Note also that, for OpenVMS I64 installations, the availability of certain options depends on the
OE you have purchased. For example, OpenVMS Management Station is available with the
Enterprise Operating Environment (EOE) and the Mission Critical Operating Environment
(MCOE).
4.3.4 Licenses and Layered Products
The upgrade procedure is designed so that you do not need to reinstall most layered products
after the upgrade. However, you might need to reinstall certain layered products because of
product-specific installation procedures.
The upgrade procedure leaves your OpenVMS license and layered product licenses intact. You
do not need to reinstall these licenses after you upgrade.
4.4 Saving Archived Files from Being Deleted by the Upgrade
By default, the upgrade procedure deletes files that were archived as filename.type_OLD by
OpenVMS remedial kits. If you do not want these files deleted, you can rename them before you
perform the upgrade. Alternatively, you can have the upgrade procedure save them by responding
to the prompts, as described in Section 6.4.4 (page 107).
4.5 Preparing the System Disk
The following sections describe how to prepare the system disk for the upgrade. Operations
include the following:
• Checking for appropriate directory structure and preserving your security protections
• Checking the SYSCOMMON directories
• Examining the system disk
• Checking the size of the system disk
• Returning authorization and AGEN$INCLUDE files to the system disk
• Verifying system parameters
4.5.1 Checking the Directory Structure and Preserving Your Security Protections
If you changed the directory structure on your system disk, the upgrade procedure does not
work correctly. Restore your system disk to a standard directory structure before you attempt
an upgrade.
The OpenVMS upgrade procedure provides new files and directories in the directory
[VMS$COMMON...]. If you have any special protections and access control lists (ACLs), you
need to reapply them to reestablish the security environment you currently have. For more
information about creating and maintaining a secure environment, see the HP OpenVMS Guide
to System Security manual.
4.5.2 Checking the SYSCOMMON Directories
For the upgrade to be successful, the SYSCOMMON directories in all system roots must be aliases
(or hard links) for the VMS$COMMON directory. To check whether this is the case, enter the
following commands if you are booted from the system disk that you are upgrading, and compare
the displayed file identifiers to ensure that they are all the same:
