OpenVMS VAX Version 7.3
Compaq recommends that you make a standalone BACKUP copy of the system
disk and, if your configuration allows it, upgrade the backup
copy. If there are problems, you will still have a working system
5.4.1 How to Back Up the System Disk
To make a backup copy of the system disk, follow the instructions in
the upgrade and installation supplement for your VAX computer. If you
do not have a removable system disk, back up your system disk to tape
and restore the image backup to the system disk. This eliminates disk
fragmentation on the system disk and creates contiguous free disk
blocks required for the upgrade. (The upgrade can fail if there are not
sufficient contiguous free blocks.) Store the backup tapes in a safe
5.4.2 How to Back Up Console Media
VAX 8200, 8250, 8300, 8350, 8600, 8650
To make a backup copy of the console media, use the SYS$UPDATE:CONSCOPY.COM procedure, as described in the upgrade and installation supplement for your VAX computer. Use the backup copy of the console media during the upgrade procedure. The upgrade procedure automatically updates the console media for you.
If your VAX computer uses one of the following console media, you did not receive a new standalone BACKUP kit with your OpenVMS VAX distribution kit:
TU58 tape cartridge
RL02 disk cartridge
Before beginning the upgrade, make sure you have a standalone BACKUP kit on one of these media. If you do not have one, create a standalone BACKUP kit using the STABACKIT.COM procedure as described in the upgrade and installation supplement for your VAX computer.
You cannot build standalone BACKUP on TU58 or RX01 console media because the OpenVMS VAX Version 7.3 kit is too large. If your VAX computer uses a TU58 or RX01, build a standalone BACKUP kit before upgrading and retain the backup copies for use with future versions of OpenVMS VAX.
To prepare the system disk for the upgrade, log in to the SYSTEM
account and, depending on your configuration, complete some or all of
the tasks described in the sections that follow.
5.5.1 Create a Nonshadowed System Disk
If you are using a volume-shadowed system disk, you must create a
nonshadowed system disk to upgrade. Follow the instructions in the
Volume Shadowing for OpenVMS manual to prepare a nonshadowed system disk for the
5.5.2 Boot the Backup Copy of Your System Disk
When the procedure asks if an automatic system reboot should be performed, press Return for NO. If you are a cluster member, choose the REMOVE_NODE option. When the procedure is finished, halt the system as described in the upgrade and installation supplement for your VAX computer.
If applicable, remove the system disk and replace it with the backup copy.
Boot the system from the backup copy of the system disk. If you do not know how to boot the system, refer to the upgrade and installation supplement for your VAX computer.
Log in to the SYSTEM account.
5.5.3 Copy UAF and Auditing Files to the System Disk
If you have moved your copy of SYSUAF.DAT to another location, copy it to the SYS$COMMON:[SYSEXE] directory for the duration of the upgrade.
Note that, if you are doing a rolling upgrade, the shared version of SYSUAF.DAT is not updated.
Move any files that you do not want changed into a user directory.
5.5.4 Rename the System Dump File
If you have a shared system dump file in SYS$COMMON:[SYSEXE], the
shared dump file cannot have the name SYSDUMP.DMP. If you have a shared
system dump file with this name, Compaq recommends that you rename it
5.5.5 Analyze the System Disk
$ ANALYZE/DISK_STRUCTURE SYS$SYSDEVICE
%ANALDISK-I-OPENQUOTA, error opening QUOTA.SYS
If you find any other errors on the system disk, repair the errors by entering the following command:
$ ANALYZE/DISK_STRUCTURE/REPAIR SYS$SYSDEVICE
Refer to the OpenVMS System Management Utilities Reference Manual for more information on the
5.5.6 Check Page and Swap Files
Compaq recommends that the page file be located on the system disk in SYS$SPECIFIC:[SYSEXE] for the upgrade.
The swap file (SWAPFILE.SYS) does not need to be located on the system disk for the upgrade, but if it is located on the system disk, the file must be located in SYS$SPECIFIC:[SYSEXE].
The page file must be at least 4600 blocks. If the upgrade procedure detects fewer than 4600 blocks, it displays a message that gives you the option of continuing the upgrade or exiting the procedure and increasing the size of the page file. If you get this message, Compaq recommends that you exit the procedure, increase the page file to at least 4600 blocks, and restart the upgrade procedure.
Enter new size for paging file:
$ SHOW DEVICE SYS$SYSDEVICE
To upgrade the OpenVMS VAX required files, the minimum
number of free blocks required is 48,950. Even if you plan to upgrade
the OpenVMS library or optional files, you might not
need more than 48,950 free blocks because many files are deleted as the
upgrade progresses, thus freeing up additional space.
5.5.8 Check Quotas and Limits
Use the Authorize utility (AUTHORIZE) to make sure the SYSTEM account has sufficient quotas and limits. To check and, if necessary, modify quota and limit values, do the following:
$ SET DEFAULT SYS$SYSTEM $ RUN AUTHORIZE UAF> SHOW SYSTEM
|Quota or Limit Name||Minimum Value|
|Open file quota (FILLM)||300|
|Buffered I/O limit (BIOLM)||18|
|Direct I/O limit (DIOLM)||18|
|AST limit (ASTLM)||24|
|Enqueue quota (ENQLM)||200|
|Buffered byte quota count (BYTLM)||32768+|
UAF> MODIFY SYSTEM/DIOLM=18
During the upgrade procedure, the system is shut down and rebooted a number of times. You must boot the system minimum (STARTUP_P1 set to MIN) before you begin the upgrade (see Section 5.6). This prevents the startup of certain system integrated products and layered products on the system during each reboot. To set the system parameter STARTUP_P1 to MIN, enter the following commands:
$ RUN SYS$SYSTEM:SYSMAN SYSMAN> PARAMETERS USE CURRENT SYSMAN> PARAMETERS SET STARTUP_P1 "MIN" SYSMAN> PARAMETERS WRITE CURRENT SYSMAN> EXIT
$ RUN SYS$SYSTEM:SYSMAN SYSMAN> PARAMETERS SHOW SCSNODE SYSMAN> PARAMETERS SHOW SCSSYSTEMID
If SCSNODE and SCSSYSTEMID are not set correctly, enter the following commands where node is a 1- to 6-character unique DECnet node name and systemid is (DECnet area * 1024) + node number:
SYSMAN> PARAMETERS USE CURRENT SYSMAN> PARAMETERS SET SCSNODE "node" SYSMAN> PARAMETERS SET SCSSYSTEMID systemid SYSMAN> PARAMETERS WRITE CURRENT . . .
Make sure the system parameter VMS5 is set to 0. If your system has a KFQSA controller, the VMS5 parameter might have been set to a nonzero value for a previous upgrade. The VMS5 parameter is reserved for use by Compaq only.
To check the value of the VMS5 parameter, enter the following commands:
$ RUN SYS$SYSTEM:SYSMAN SYSMAN> PARAMETERS USE CURRENT SYSMAN> PARAMETERS SHOW VMS5 Parameter Name Current Default Minimum Maximum Unit Dynamic -------------- ------- ------- ------- ------- ---- ------- VMS5 1 0 0 -1
If the current value of VMS5 is not 0, set it to 0 by entering the following commands:
SYSMAN> PARAMETERS USE CURRENT SYSMAN> PARAMETERS SET VMS5 0 SYSMAN> PARAMETERS WRITE CURRENT SYSMAN> EXIT
During an upgrade, user disks are not mounted and SYLOGICALS.COM is not invoked, so AUTOGEN can access only data files that are on the system disk and whose file specification includes a logical name that is shipped as part of the OpenVMS operating system. Therefore, if you use AGEN$INCLUDE in SYS$SYSTEM:MODPARAMS.DAT to point to data files that are not on the system disk, follow these steps before you perform an upgrade:
If you do not move referenced data files to the system disk, AUTOGEN
uses whatever information is available during the upgrade and
parameters might be set to values considerably different from what you
5.5.11 Add Modified System Parameters to MODPARAMS.DAT
Any system parameter values that you modified and did not enter in MODPARAMS.DAT are lost during the upgrade. To retain the values of these parameters, enter their names in MODPARAMS.DAT and the value that AUTOGEN needs to add to the default minimum value.
For example, if you modified GBLPAGES by 128 pages above the default, add the following line to SYS$SYSTEM:MODPARAMS.DAT:
When AUTOGEN runs after the upgrade, it uses the values in MODPARAMS.DAT.
To prepare the system for the upgrade, use the procedure described in
the following sections.
5.6.1 Enable Auto Restart or Manual Reboot
If your computer uses console media, set the computer to restart automatically. For some VAX computers this means setting one or more switches. For others, this means entering certain console mode commands. To determine how to enable auto restart, refer to the upgrade and installation supplement for your VAX computer.
If you have a system that does not use console media, set your system
so you can reboot it manually. For more information, refer to the
upgrade and installation supplement for your VAX computer.
5.6.2 Shut Down and Reboot the System
Shut down and reboot the system to activate any system parameters that you changed (STARTUP_P1, for example). To shut down the system, enter the following command:
When the procedure asks if an automatic system reboot should be performed, type Y (for YES) and press Return.
After the system reboots, log in to the SYSTEM account.
5.6.3 Prevent Interactive Logins
$ SET LOGINS/INTERACTIVE=0
$ SHOW LOGICAL SYS$NODE
If the system displays the following message, DECnet is not running on your system and you can proceed to Section 5.6.6:
%SHOW-S-NOTRAN, no translation for logical name SYS$NODE
If the system responds with a translation for SYS$NODE, then DECnet is running on your system.
If you set STARTUP_P1 to MIN as described in Section 5.5.9, DECnet
should not be running. To set STARTUP_P1 to MIN, repeat all of the
preceding steps beginning with Section 5.5.9. Note that you must shut
down and reboot the system for any changes you make to system
parameters to take effect.
5.6.5 Check for Volume Shadowing
If you have volume shadowing software installed on your system but are unsure which phase, you can enter the following commands:
$ RUN SYS$SYSTEM:SYSMAN SYSMAN> PARAMETERS USE CURRENT SYSMAN> PARAMETERS SHOW SHADOWING
If the SHADOWING parameter is 1 or 3, then you have phase I volume shadowing software currently loaded on your system. For information about migrating to phase II, refer to Volume Shadowing for OpenVMS.
At the beginning of an upgrade, the procedure checks the setting of the SHADOWING system parameter. If you have not migrated to phase II and the procedure detects the presence of phase I, it displays the following message and asks if you want to continue the upgrade:
The SHADOWING system parameter (currently set to 1) specifies phase I of volume shadowing, which is no longer available as of OpenVMS VAX Version 6.1. If you continue with this upgrade, volume shadowing will not be present on your system after the upgrade has completed. Please consult the Volume Shadowing for OpenVMS manual for instructions about moving to phase II of volume shadowing. * Do you want to continue the upgrade?
At that point, you can exit the upgrade procedure, follow the
instructions in Volume Shadowing for OpenVMS for migrating to phase II volume
shadowing, and restart the upgrade procedure from the beginning. If you
continue with the upgrade without migrating to phase II, the volume
shadowing software will not be present on your system after the upgrade
5.6.6 Stop Queues
It is not necessary to stop queues on nodes that you are not upgrading.
5.7 Gathering Information for the Upgrade
At different points during the upgrade, the procedure prompts you to supply information. To save time once the procedure begins, be sure you have the following information readily available. Remember, entering incorrect information during the upgrade could force you to repeat the entire upgrade procedure.
|Device names||You will need to specify the device names for the drives that will hold the distribution media and the system disk.|
|Passwords||You will be prompted to type passwords of at least 8 characters for the SYSTEM, SYSTEST, and FIELD accounts.|
|Optional components and OpenVMS Management Station files||
The upgrade procedure prompts you to specify whether you want to
install the library (VMS073.C), optional (VMS073.D) OpenVMS components,
and OpenVMS Management Station software PC files (VMS073.F).
Appendix D lists the files included in these save sets.
You can save some space on your system disk if you choose not to install these components, but be sure to review Appendix D before deciding.
|Location for Help Message utility||Save set VMS073.E contains the online Help Message utility, which you can install on your system disk or on an alternate disk. (However, if you copied the distribution kit to some other media from which you will be performing the installation, you cannot install this save set on that media.)|
The installation procedure prompts you to specify which of the
following DECwindows components you want to install:
Note that you must install the DECwindows Motif for OpenVMS VAX (previously called VMS
DECwindows Motif) layered product if you want to run the DECwindows
software. DECwindows Motif for OpenVMS VAX Version 1.2-4 is the minimum supported version
for systems running OpenVMS VAXVersion 7.3. If you do not
know which version of DECwindows Motif for OpenVMS VAX you are currently running on your
system, you can check by entering the following command:
Also note that the layered product does not have the DECwindows base and workstation support components. To get full DECwindows support, you must select the DECwindows components provided with the OpenVMS VAX Version 7.3 kit and install the separate DECwindows Motif for OpenVMS VAX layered product, which supports both Motif and XUI environments.
