Before Upgrading the OpenVMS VAX Operating System
5.6 Preparing the System
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
Phase I (controller-based) volume shadowing is no longer available. Phase
II (host-based) volume shadowing is designed to fully replace phase I with
significantly enhanced features.
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 has completed.
5.6.6 Stop Queues
To stop all batch and print queues on the node you are upgrading, enter the
following command:
$ STOP/QUEUES/ON_NODE
It is not necessary to stop queues on nodes that you are not upgrading.
