# Recovering the OpenVMS File System Data

Use this procedure to perform a disaster recovery restore.

In this procedure, DKA2 refers to the backup system image and DKA0 refers to the disk that is the destination for the restore.

The example commands are for illustrative purposes. Use values that pertain to your installation when you follow this procedure.

#### Before You Begin

1. Boot the system from the backup image.

   The new disk is installed.

2. If the software does not exist on the backup system disk (in this example, DKA2), install the Commvault software.

3. Start the services. On the command line, type the following command.

       @DKA2:[SIMPANA_INSTALL_DIRECTORY.BIN]CVOV_START

4. Initialize the new disk (in this example, DKA0). On the command line, type the following command.

   Use values that are appropriate for your configuration. Hard links must be enabled for the restore operation.

       INITIALIZE/GPT/SYSTEM/STRUCTURE=5/HEADERS=60000/VOLUME_CHARACTERISTICS=HARDLINKS DKA0: I64SYS

5. Mount the disk (in this example, DKA0). On the command line, type the following command.

       MOUNT/SYSTEM DKA0: I64SYS

#### Procedure

1. From the CommCell Browser, expand Client Computers> client > Proxy File System.

2. Right-click the backup_set and click Browse and Restore.

3. In the Browse and Restore Options dialog box, click View Content.

4. In the left pane, select the entire system to restore.

5. Click Recover All Selected.

   The Restore Options dialog box is displayed.

6. On the General tab, select the restore options.

   1. Clear the Overwrite Files check box.

   2. From the Destination client list, select the restore destination.

   3. Clear the Restore to same folder check box.

   4. In the Specify destination path box, click Browse.

      The Browsing for destination folder dialog box is displayed.

   5. Browse to the top-level directory on the restore system and then click OK. For example, browse to /SCS314$DKA0.

   6. In the Preserve Source Path section, select Remove.

   7. In the level from beginning of the source path box, type 1.

7. Click OK.

#### What to Do Next

1. Set the boot block. On the command line, type the following command.

       SET BOOTBLOCK /I64 DKA0:[VMS$COMMON.SYS$LDR]SYS$EFI.SYS

2. Use the menu driven utility to add an entry to the EFI interface menu. On the command line, type the following command.

       @SYS$MANAGER:BOOT_OPTIONS.COM
