The following sections describe how to back up
the system disk.
F.4.1 Getting Started
Before you back up the system disk, do the following:
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).
down all systems booted from that disk.
the operating system media. (For booting the OpenVMS Integrity servers
OE DVD, see Section B.6. For booting the OpenVMS Alpha CD, see Section A.1.)
the DCL option (8) on 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 distribution media (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 8.4
2) Display layered products that this procedure can install
3) Install or upgrade layered products
4) Show installed products
5) Reconfigure installed products
6) Remove installed products
7) Find, Install, or Undo patches; Show or Delete recovery data
8) Execute DCL commands and procedures
9) Shut down this system

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
F.4.2 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:
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, see the HP OpenVMS System Manager's Manual, Volume
1: Essentials and the HP OpenVMS System Management
Utilities Reference Manual: A-L, and see the description
of the INITIALIZE and BACKUP commands in the HP OpenVMS
F.4.5 Logging Out, Shutting Down, and Rebooting
After you complete the backup operation:
the LOGOUT command to exit the DCL environment and return to the menu.
the shutdown option (9).
the shutdown completes, boot from the system disk.
