The following sections describe how to back up the system
disk.
Getting Started Before you back up the system disk, do the following:
In an OpenVMS
Cluster environment, dismount the system disk from all systems in
the cluster that have the disk mounted as a data disk (rather than
as the system disk).
Shut down all systems booted from that disk.
Boot the operating system media. (
Booting Operations explains how to boot the OpenVMS I64 OE DVD.)
Choose the DCL option (7) from the menu. For example:
****************************************************************
You can install or upgrade the OpenVMS I64 operating system
or you can install or upgrade layered products that are included
on the OpenVMS I64 operating system CD/DVD.
You can also execute DCL commands and procedures to perform
"standalone" tasks, such as backing up the system disk.
Please choose one of the following:
1) Upgrade, install or reconfigure OpenVMS I64 Version 8.2-1
2) Display products and patches that this procedure can install
3) Install or upgrade layered products and patches
4) Show installed products
5) Reconfigure installed products
6) Remove installed products
7) Execute DCL commands and procedures
8) Shut down this system

At the triple dollar sign prompt ($$$), enter the
SHOW DEVICES command.
Examine the list of devices to determine which device
is the source drive (the system disk you want to back up) and which
device is the target drive (the supported disk or tape device that
will hold the backed up files).
Mounting Devices After you determine the source drive and target drive, mount
those devices (and any other output devices you plan to use) before
you perform any backup operations. Enter the MOUNT commands in
the following format:
source-drive is the name of
the drive holding the system disk.
target-drive is the name of
the drive that will hold the backup files.
Performing the System
Disk Backup When the system disk and output devices are mounted, back
up the system disk by entering the BACKUP command in the following
format:
In this example, the system disk and a target disk are mounted
so the BACKUP command can create a backup disk. (You can use a
backup disk as a system disk.)
Changing the Disk
Volume Cluster Size The BACKUP/IMAGE command maintains a set of disk volume parameters
from the input volume, altering attributes such as the disk volume
cluster size as appropriate for the target device. (Cluster size
refers to the basic unit of space allocation on the disk, not to
OpenVMS Cluster environments.)
To change the disk volume cluster size, you must restore the
disk contents to a disk that has been previously initialized with
the desired cluster size (using BACKUP/IMAGE/NOINITIALIZE). For
more information about initializing a disk and using the BACKUP
command, refer to the HP OpenVMS System Manager's Manual, Volume 1: Essentials
and the HP OpenVMS System Management Utilities Reference Manual: A--L
, and
refer to the description of the INITIALIZE and BACKUP commands in
the HP OpenVMS DCL Dictionary
.
Logging Out, Shutting
Down, and Rebooting After you complete the backup operation:
Enter the LOGOUT
command to exit the DCL environment and return to the menu.
Choose the shutdown option (8).
After the shutdown completes, boot from the system
disk.
