text: An intermediate target disk (not the oldest or the newest) treats the set of newer target 
  volumes and the true source volume as a type of composite source. It treats all older volumes 
  as a kind of target (and behaves like a source to them). 
  
  **Target read with Multiple Target FlashCopy**
  Target reading with multiple targets depends on whether the grain was copied: 
  
  (cid:2) If the grain that is being read is copied from the source to the target, the read returns data 
  from the target that is being read. 
  
  (cid:2) If the grain is not yet copied, each of the newer mappings is examined in turn. The read is 
  
  performed from the first copy (the oldest) that is found. If none is found, the read is 
  performed from the source. 
  
  For example, as shown in Figure 11-13 on page 454, if the yellow grain on T2 is read, it 
  returns “H” because there is no newer target than T2. Therefore, the source is read. 
  
  As another example, as shown in Figure 11-13 on page 454, if the red grain on T0 is read, 
  it returns “E” because there are two newer targets for T0, and T1 is the oldest of them.
