Before Upgrading the OpenVMS VAX Operating System
5.5 Preparing the System Disk
Make sure the system parameters SCSNODE and SCSSYSTEMID are defined on
your system. To determine whether these parameters are defined on your system,
enter the following commands:
$ 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$SYSTEM:SYSMAN
SYSMAN> PARAMETERS USE CURRENT
SYSMAN> PARAMETERS SHOW VMS5
Parameter Name Current Default Minimum Maximum Unit Dynamic
-------------- ------- ------- ------- ------- ---- -------
VMS5 1 0 0 -1
If the current value of VMS5 is not 0, set it to 0 by entering the following
commands:
SYSMAN> PARAMETERS USE CURRENT
SYSMAN> PARAMETERS SET VMS5 0
SYSMAN> PARAMETERS WRITE CURRENT
SYSMAN> EXIT
5.5.10 Check AGEN$INCLUDE Files
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:
1. Copy any files that you want AUTOGEN to include to a directory on the
system disk.
2. For each file that you move, change the file specification on the
AGEN$INCLUDE line in SYS$SYSTEM:MODPARAMS.DAT to point to
the new location of the file on the system disk.
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 intend.
