text: **11.1.13 FlashCopy and image mode Volumes**
  
  FlashCopy can be used with image mode volumes. Because the source and target volumes 
  must be the same size, you must create a target volume with the same size as the image 
  mode volume when you are creating a FlashCopy mapping. To accomplish this task with the 
  CLI, use the**svcinfo lsvdisk -bytes volumename**command. The size in bytes is then used 
  to create the volume that is used in the FlashCopy mapping. 
  
  This method provides an exact number of bytes because image mode volumes might not line 
  up one-to-one on other measurement unit boundaries. Example 11-1 shows the size of the 
  ITSO-TSTRS001 volume. The ITSO-TSTRS002 volume is then created, which specifies the same 
  size.
