5.4 Backing Up the System Disk
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 place.
5.4.2 How to Back Up Console Media
If you have one of the following VAX computers, you must also make a backup
copy of the 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
RX33 diskette
RX50 diskette
RX01 diskette
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.
Note
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.
5.5 Preparing the System Disk
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 upgrade.
