VMXBKP02 Utility

The VMXBKP02 EXEC uses the IBM DDR utility to create a mirror image of your source directory minidisk (DRCT) to one of your minidisks.

VMXBKP02 [vaddr]

Authorizations

The user ID that runs this utility needs BACKUP authorization in the AUTHORIZ CONFIG file, and must have access to both the VMXBKP02 EXEC on the deployed administration minidisk (usually the VMDIRECT 176) minidisk, and the public minidisk where the VMDIRECT MODULE resides.

Definitions

vaddr

Specifies the virtual address of the backup minidisk. The backup minidisk cannot be your A‑disk, and you must have a write link to it. The default virtual address is 200.

Description

VMXBKP02 links to the CA VM:Director DRCT minidisk to perform the backup and detaches from this minidisk upon completion. A link password is not required because a temporary directory link is added to the issuing virtual machine’s directory entry. After the backup is completed, CA VM:Director erases the directory entries on the CA VM:Director BKUP minidisk because all recent changes are now backed up.

To protect against data loss in the event of hardware failures, allocate your backup minidisk on a different real DASD volume from your DRCT minidisk.

CA VM:Director must be up and running to use this utility.

If the CA VM:Director service virtual machine has a user ID other than VMDIRECT, the VMXBKP02 EXEC must be modified to use the new user ID.

Note: VMXBKP02 erases all old files from the vaddr minidisk before it copies the DRCT minidisk to the backup minidisk.

Examples

• Create a mirror image of your source directory (DRCT) minidisk to a minidisk that you own:
  1. Choose a minidisk to which you want VMXBKP02 to write your mirror image.
  2. Enter the following command:

     VMXBKP02 vaddr
     

• Later, to recover your source directory:
  1. Create a new DRCT minidisk.
  2. Copy the source directory database files from your backup minidisk to the new DRCT minidisk.
  3. Update the DRCT minidisk using the files that have accumulated on the CA VM:Director BKUP minidisk since VMXBKP02 last ran
