text: Figure 11-22 Creating a FlashCopy mapping with an existing target 
  
  The Create FlashCopy Mapping window opens as shown in Figure 11-23. In this window, 
  you create the mapping between the selected source volume and the target volume you 
  want to create a mapping with. Then, click**Add**. 
  
  **Important:**The source volume and the target volume must be of equal size. Therefore, 
  only targets of the same size are shown in the list for a source volume. 
  
  Volumes that are a target in a FlashCopy mapping cannot be a target in a new 
  mapping. Therefore, only volumes that are not targets can be selected.
