Configuration: Premium Feature—Virtual Disk Copy

The Virtual Disk Copy premium feature includes these items:

• The Create Copy Wizard, which assists in creating a virtual disk copy
• The 

Copy Manager, which monitors virtual disk copies after they have 

been created 

A virtual disk copy fails all snapshot virtual disks that are associated with the 

target virtual disk, if any exist. If you select a source virtual disk of a snapshot 

virtual disk, you must disable all of the snapshot virtual disks that are 

associated with the source virtual disk before you can select it as a target 

virtual disk. Otherwise, the source virtual disk cannot be used as a target 

virtual disk.
A virtual disk copy overwrites data on the target virtual disk and automatically 

makes the target virtual disk read-only to hosts
If eight virtual disk copies with a status of In Progress exist, any subsequent 

virtual disk copy has a status of Pending, which stays until one of the eight 

virtual disk copies completes. 

If a modification operation is running on a source virtual disk or a target 

virtual disk, and the virtual disk copy has a status of In Progress, Pending, or 

Failed, the virtual disk copy does not take place. If a modification operation is 

running on a source virtual disk or a target virtual disk after a virtual disk copy 

has been created, the modification operation must complete before the 

virtual disk copy can start. If a virtual disk copy has a status of In Progress, any 

modification operation does not take place.

The Create Copy Wizard guides you through:

1 Selecting a source virtual disk from a list of available virtual disks
2 Selecting a target virtual disk from a list of available virtual disks
3 Setting the copy priority for the virtual disk copy

When you have completed the wizard dialogs, the virtual disk copy starts, and 

data is read from the source virtual disk and written to the target virtual disk.
