Bacpac provides tremendous power and flexibility when duplicating VMS disks from one system to another. Qualifiers allow you to specify how to handle situations such as:
- Mount the target disk if it is not mounted
- Dismount the target disk if it is already mounted
- Leave the target disk mounted after the duplication completes
- Give the target disk a different volume name
- Keep a saveset backup in addition to creating a duplicate disk
Following are examples of duplicating disks using BacPac:
- Duplicate a local disk on node alpha to a remote target disk on node bravo, but only if the target disk is not mounted. Leave the target disk unmounted after the duplication is complete:
alpha $ BACPAC DISK$USER1: BRAVO::$3$DKA0: /DUP /IMAGE /MOUNT
- Duplicate a local disk on node alpha to a remote target disk on node bravo. Dismount the target disk if it is mounted. Leave the target disk unmounted after the duplication is complete:
alpha $ BACPAC DISK$USER1: BRAVO::$3$DKA0: /DUP /IMAGE /DISMOU /MOU
- Duplicate a local disk on node alpha to a remote target disk on node bravo. Dismount the target disk if it is mounted. Leave the target disk mounted cluster wide after the duplication is complete:
alpha $ BACPAC DISK$USER1: BRAVO::$3$DKA0: /DUP /IMAGE /DISMOU /MOU /REMOU
- Duplicate a local disk on node alpha to a remote target disk on node bravo. Dismount the target disk if it is mounted. Leave the target disk mounted cluster wide after the duplication is complete. Give the target disk a different volume name:
alpha $ BACPAC DISK$USER1: BRAVO::$3$DKA0: /DUP /IMAGE /DISMOU /MOU/REMOU/VOL=USER1DUP
- Duplicate a remote disk on node bravo to a local target disk on node alpha. Dismount the target disk if it is mounted. Leave the target disk mounted cluster wide after the duplication is complete. Give the target disk a different volume name:
alpha $ BACPAC BRAVO::DISK$USER2: $4$DKA100: /DUP /IMAGE /DISMOU /MOU /REMOU/VOLl=USER2DUP
