After completion of the virtual disk copy of a snapshot (legacy), the legacy snapshot is disabled. After completion of the
virtual disk copy using a snapshot image, the snapshot image is deleted and the snapshot virtual disk is disabled.

NOTE: You can have a maximum of eight virtual disk copies in progress at one time. If you try to create more than
eight virtual disk copies at one time, the RAID controller modules return a status of Pending until one of the virtual
disk copies that is in progress finishes and returns a status of Complete.

NOTE: Snapshots created using older (legacy) premium feature versions cannot be managed using newer
snapshot premium feature options. Also, a virtual disk in a snapshot group cannot be a target for a virtual disk
copy. If you want to choose the base virtual disk of an older (legacy) snapshot virtual disk as your target virtual
disk, you must first disable all snapshot (legacy) virtual disks that are associated with the base virtual disk.

The following table lists the Virtual Disk Copy commands.

NOTE: These commands apply when you are using a snapshot or a snapshot (legacy) image.

Creating A Virtual Disk Copy

Before creating a virtual disk copy, ensure that a suitable target virtual disk exists on the storage array, or create a new
target virtual disk specifically for the virtual disk copy. The target virtual disk must have a capacity equal to or greater
than the source virtual disk.
You can have a maximum of eight virtual disk copies in progress at one time. Any virtual disk copy greater than eight has
a status of Pending until one of the virtual disk copies with a status of In Progress completes.
The following steps show the general process for creating a virtual disk copy:
