Alternative Backup and Restore Procedure (Minimum OpenVMS Environment)

This section describes an alternative method of performing backup and restore operations. It is similar to creating a Standalone Backup directory on a disk, as supported by OpenVMS VAX systems and certain earlier versions of OpenVMS Alpha (using SYS$UPDATE.STABACKIT.COM). Supported by both OpenVMS Alpha and I64 systems, this method installs a Minimum OpenVMS Environment (install with no options) on another disk from which you can perform your backup and restore operations on the system disk. The Minimum OpenVMS Environment is created in the SYSE root ([SYSE]) on the disk, which runs a subset of OpenVMS and is indicated by the $$$ system prompt. Use this method under the following conditions:

If you do not have access to the operating system CD or DVD and its menu system

If you want to back up a shadowed system disk without disabling the shadow set

It is also possible to back up your running system disk by using the qualifier /IGNORE=INTERLOCK with the BACKUP command and ignoring warning messages. However, that method requires that all other use of the system be suspended, including disabling logins, stopping print and batch queues, and turning off networking software. In addition, you cannot use this method to restore files to the running system disk. Because of these limitations, HP recommends that if you must use an alternative method to back up or restore the system disk, you use the method described in this section.

Preparing an Alternate System Disk

Prepare an alternate system disk as follows:

Using the SHOW DEVICE command, identify a data disk on which you can install the operating system, with no options. This will be your target disk during that installation. To install the operating system with no options on your target disk, you will need the following amount of free disk space:
- OpenVMS Alpha: approximately 75,000 blocks
- OpenVMS I64: approximately 1,05,000 blocks
Existing data will remain on the disk.

The target disk must be mounted privately to your process. (This prevents other users from accessing this disk during the installation and backup procedures.) Therefore, if the target disk was mounted with /SYSTEM, /CLUSTER, /GROUP, or /SHARE, dismount that disk and mount it without using those qualifiers or the /FOREIGN qualifier. For example:
```
$ MOUNT/OVERRIDE=IDENTIFICATION DKA200 
```

For OpenVMS Alpha, enter the following command to install the operating system, with no options, on the target disk:
```
$ @SYS$SYSTEM:AXPVMS$PCSI_INSTALL_MIN.COM [target-disk]
```
For OpenVMS I64, enter the following command:
```
$ @SYS$SYSTEM:I64VMS$PCSI_INSTALL_MIN.COM [target-disk]
```
(The procedure prompts you for a device name if you do not specify it on the command line.)

As the procedure completes the installation, the display is similar to the following (on Alpha systems):

    .
    The installation of minimum OpenVMS Alpha is now complete.
 
    Use the following command to boot minimum OpenVMS:
 
        BOOT -FLAGS E,O device-name
 
    (Your system may require additional parameters to boot.)

If your system is a cluster member, HP recommends that you shut down the entire OpenVMS Cluster system before you back up your system disk. This will prevent you from creating a partitioned cluster and from jeopardizing the integrity of your data in any other way.

Using the Alternate System Disk

Use the alternate system disk (on which you installed the operating system with no options) to perform backup and restore operations as follows:

Shut down your system.

Boot the alternate system disk from the SYSE root. For example, from an OpenVMS Alpha system:

>>> BOOT -FLAGS E,0 DKA200

For OpenVMS I64 systems, you can add the alternate system disk as a boot option in the EFI Boot Manager menu by using the OpenVMS I64 Boot Manager (BOOT_OPTIONS.COM) utility, as explained in step 20 of Installing OpenVMS Using Option 1 of the Operating System Menu (Step 20 is found several pages after the start of the section). When prompted, set the flags as e,0. Alternatively, boot the alternate system disk manually by entering the following command at the EFI Shell prompt, where fsn: (such as fs1:) is the device associated with the system disk:

Shell>fsn:\efi\vms\vms_loader.efi -flags e,0

The system automatically logs you in to the SYSTEM account and then displays a triple dollar sign prompt ($$$).

During the boot and login operations on this minimum version of the operating system, you can ignore license messages that are similar to the following:

%LICENSE-I-NOLICENSE, no license is active for this software product

If your system disk is shadowed, install and load a Volume Shadowing license on this data disk. You will then be able to back up the shadowed system disk from this data disk without disabling the shadow set.
HP recommends that you do not install any other licenses, including OpenVMS licenses, on this alternate system. You will be able to use the system only from the console.

Mount the system disk and any output devices you plan to use during the backup or restore operations. See Mounting Devices for more information.

Perform the necessary backup or restore operations by entering the appropriate BACKUP commands. For examples using the BACKUP command to back up the system disk, see Performing the System Disk Backup; for examples using the BACKUP command to restore the system disk, see Performing the System Disk Restore.

Shut down the system.

Boot from your original system disk.
