text: When copy 1 is synchronized, copy 0 is deleted. You can monitor the progress of volume copy 
  synchronization by using the**lsvdisksyncprogress**command. 
  
  **7.8.6 Splitting a mirrored volume**
  
  The use of the**splitvdiskcopy**command creates an independent volume in the specified I/O 
  Group from a volume copy of the specified mirrored volume. In effect, the command changes 
  a volume with two copies into two independent volumes, each with a single copy. 
  
  If the copy that you are splitting is not synchronized, you must use the**-force**parameter. If 
  you are attempting to remove the only synchronized copy of the source volume, the command 
  fails. However, you can run the command when either copy of the source volume is offline.
