Before Upgrading the OpenVMS VAX Operating System
5.5 Preparing the System Disk
5.5.2 Boot the Backup Copy of Your System Disk
If you need to boot the backup copy of your system disk or if you are upgrading an
OpenVMS Cluster systems environment, enter the following command (otherwise,
go to the next step):
$ @SYS$SYSTEM:SHUTDOWN
When the procedure asks if an automatic system reboot should be performed,
press Return for NO. If you are a cluster member, choose the REMOVE_NODE
option. When the procedure is finished, halt the system as described in the
upgrade and installation supplement for your VAX computer.
If applicable, remove the system disk and replace it with the backup copy.
Boot the system from the backup copy of the system disk. If you do not know how
to boot the system, refer to the upgrade and installation supplement for your VAX
computer.
Log in to the SYSTEM account.
5.5.3 Copy UAF and Auditing Files to the System Disk
The current copies of the SYSUAF.DAT and the VMS$AUDIT_SERVER.DAT files
must be on the system disk; otherwise, you cannot proceed with the upgrade.
If you have moved your copy of SYSUAF.DAT to another location, copy it to the
SYS$COMMON:[SYSEXE] directory for the duration of the upgrade.
If you have moved your copy of VMS$AUDIT_SERVER.DAT to another location,
copy it to the SYS$COMMON:[SYSMGR] directory.
Note that, if you are doing a rolling upgrade, the shared version of SYSUAF.DAT
is not updated.
Move any files that you do not want changed into a user directory.
5.5.4 Rename the System Dump File
If you have a shared system dump file in SYS$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 to
SYS$COMMON:[SYSEXE]SYSDUMP-COMMON.DMP.
5.5.5 Analyze the System Disk
To analyze the system disk for inconsistencies and errors in the file structure,
enter the following command:
$ ANALYZE/DISK_STRUCTURE SYS$SYSDEVICE
The following message represents normal behavior; you can ignore it:
%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 ANALYZE/DISK_STRUCTURE command.
