System Management Features
Volume Shadowing for OpenVMS Volume Shadowing for OpenVMS introduces three new features:
• Minicopy operation, which is a streamlined copy operation.
Minicopy can significantly decrease the time it takes to perform
a full copy operation and can significantly increase the availability
of the shadow sets that use this feature.
• New qualifiers added to the DISMOUNT and SET commands for
disaster tolerant support for OpenVMS Cluster systems.
• A new /SHADOW qualifier to the INITIALIZE command.
Programming Features
