NOTE: If you ordered Premium Features for Virtual Disk Copy, you received a Premium Features Activation card
shipped in the same box as your Dell PowerVault MD storage array. Follow the directions on the card to obtain a
key file and to enable the feature. For more information, see "Premium Feature — Virtual Disk Copy" in the
Manual .
The Virtual Disk Copy feature enables you to copy data from one virtual disk (the source) to another virtual disk (the
target) in a single storage array. You can use this feature to perform the following functions:
Back up data.
Copy data from disk groups that use smaller capacity physical disks to disk groups using larger capacity
physical disks.
Restore snapshot virtual disk data to the associated source virtual disk.
NOTE: The preferred method is to perform a Virtual Disk Copy from a Snapshot Virtual Disk. This allows the original
virtual disk used in the Snapshot operation to remain in full use while the Snapshot of this virtual disk is used as the
source for the virtual disk copy operation.
NOTE: The Virtual Disk Copy for any Virtual Disk cannot be mounted on the same host as the source Virtual Disk.
The Microsoft Windows operating system does not allow assigning a drive letter to the Virtual Disk Copy.
The following table lists the Virtual Disk Copy commands and briefly describes what the commands do.
