text: You must use the**-mdisk**parameter to specify an MDisk that has a mode of unmanaged. The 
  **-fmtdisk**parameter cannot be used to create an image mode volume. 
  
  **Capacity:**If you create a mirrored volume from two image mode MDisks without specifying 
  a**-capacity**value, the capacity of the resulting volume is the smaller of the two MDisks. 
  The remaining space on the larger MDisk is inaccessible. 
  
  If you do not specify the**-size**parameter when you create an image mode disk, the entire 
  MDisk capacity is used. 
  
  Use of the**mkvdisk**command to create an image mode volume is shown in Example 7-5.
