Examining the System
Disk
Examine and repair (if necessary) the system disk using the
ANALYZE/DISK_STRUCTURE command. (Refer to the HP OpenVMS System Management Utilities Reference Manual: A--L for more
information about this command.) Use the following procedure:
Ignore the following message:$
ANALYZE/DISK_STRUCTURE SYS$SYSDEVICE
%ANALDISK-I-OPENQUOTA, error opening QUOTA.SYS
$
ANALYZE/DISK_STRUCTURE/REPAIR SYS$SYSDEVICE
Checking the SYSCOMMON
Directories
For the upgrade to be successful, the SYSCOMMON directories
in all system roots must be aliases (or hard links) for the VMS$COMMON
directory. To check whether this is the case, execute the following
commands if you are booted from the system disk that you will be
upgrading, and compare the displayed file identifiers to ensure
that they are all the same:
If you did not boot from the system disk that you will be upgrading, mount the disk to be upgraded and specify the actual device name in the command. For example, if the system disk to be upgraded is mounted on DKA100, you would use commands similar to the following:$
DIRECTORY/FILE_ID/NOHEADING/NOTRAILING SYS$SYSDEVICE:[000000]VMS$COMMON.DIR
$
DIRECTORY/FILE_ID/NOHEADING/NOTRAILING SYS$SYSDEVICE:[SYS*]SYSCOMMON.DIR
Output from the first command should list a single file. Output from the second command should list one file for each system root on the disk. Check whether the file ID is the same for all of the listed files and take action as follows:$
DIRECTORY/FILE_ID/NOHEADING/NOTRAILING DKA100:[000000]VMS$COMMON.DIR
$
DIRECTORY/FILE_ID/NOHEADING/NOTRAILING DKA100:[SYS*]SYSCOMMON.DIR
Checking the Size
of the System Disk
It is difficult to determine in advance how many blocks of
disk space you will need for the upgrade. It depends on how many
files you have on the target disk already and on how many components
you select during the upgrade procedure. However, the following
information will help:
To see how much space you have on the system disk, enter the following command:
$
SHOW DEVICE SYS$SYSDEVICE
Returning Authorization
and AGEN$INCLUDE Files to the System Disk
If you have placed authorization and AGEN$INCLUDE files
on disks other than the system disk, the upgrade procedure will
not find these files. This is because the other disks will not
be mounted during the upgrade. In addition, the logical names you
have set up to point to these files will not be defined. The following
sections explain how to make these files available to the upgrade
procedure.
Authorization
Files
OpenVMS allows you to relocate certain system files (mostly
authorization files) off the system disk. You do this by copying
the files to another location and then defining logical names as
documented in the file SYS$SYSTEM:SYLOGICALS.TEMPLATE. The logical
names are defined in SYS$STARTUP:SYLOGICALS.COM. You can modify
this file during an upgrade.
When you boot your system from the OpenVMS operating system CD or DVD, the logical names pointing to these files are not defined, and the disks where they are located are not mounted. Because of this, the upgrade cannot access the relocated files, possibly resulting in an incorrect or incomplete upgrade. The upgrade might finish without error, but the files might not be in place as expected.
Before upgrading your system, check the definitions of these logical names on your system. (If a file has not been relocated, the corresponding logical name might not be defined. This is acceptable.) If any logical name points to a location or file name other than the location and file name listed in Logical Names for Relocated Authorization Files, return the file to the default location and file name (see the extra requirements mentioned for the SYS$DUMP_PRIORITY.DAT file in the footnote to Logical Names for Relocated Authorization Files). To prevent the system from referencing the files located off the system disk, either delete the associated logical name (using the DCL command DEASSIGN/SYSTEM/EXEC) or shut down the operating system and reboot from the operating system CD or DVD. After the upgrade and before booting the operating system, you can move these files back to their original locations off the system disk.

AGEN$INCLUDE Files
If you use the AGEN$INCLUDE feature in SYS$SYSTEM:MODPARAMS.DAT
to include files containing additional parameter settings, and the
files that are being included are not on the system disk, then do
the following before upgrading:
After the upgrade is complete, you can move these included files back to their original locations. If you do so, remember to re-set the AGEN$INCLUDE entries in SYS$SYSTEM:MODPARAMS.DAT.
Verifying System
Parameters
Verify (and modify if necessary) system parameters, described
as follows. (If necessary, refer to the HP OpenVMS System Manager's Manual, Volume 2: Tuning, Monitoring, and Complex Systems for more information
about modifying system parameters.) Any system parameters that you
modified and did not enter in SYS$SYSTEM:MODPARAMS.DAT
are lost during the upgrade. To retain these parameters, enter their
names and the values that you have in use for them in SYS$SYSTEM:MODPARAMS.DAT.
(When AUTOGEN runs after the upgrade, it uses the values in SYS$SYSTEM:MODPARAMS.DAT.)
For example, if the current value of GBLPAGES is 30000, and you modified GBLPAGES by 128 pages above the default, add the following line to SYS$SYSTEM:MODPARAMS.DAT:
MIN_GBLPAGES=30128
!Increased by 128 by PLM for product z 12/12/04
AUTOGEN will use this new value as a base, comparing it with
collected data and increasing the value of GBLPAGES if necessary.
Each time AUTOGEN is run, it will make the same comparison and adjust
the value of GBLPAGES, but never below the minimum indicated by
MIN_GBLPAGES. During an upgrade, everything is set back to the default. Use current feedback.
If you modify system parameters, note the following:
For more information about using AUTOGEN as recommended, see Running AUTOGEN to Tune the System. |
If your system was upgraded previously, a new SYS$SYSTEM:MODPARAMS.DAT file was created then. This file has comments and possibly duplicated entries that were created during that upgrade. If you upgrade again, SYS$SYSTEM:MODPARAMS.DAT can become unnecessarily large and potentially confusing. HP recommends that you edit and reorganize SYS$SYSTEM:MODPARAMS.DAT before you upgrade again.
On a cluster system disk, MODPARAMS.DAT should exist in SYS$SYSROOT:[SYSEXE] for each root. You must edit MODPARAMS.DAT as necessary for each root. |
1 Copies of this file might exist in multiple system-specific directories. If the file was moved off the system disk, then before upgrading, in addition to moving this file to its default location (and to its default name) on the system disk, you must manually merge and place copies of this file in the common directory.
