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.
