text: **Stopping process in a Multiple Target FlashCopy - Cleaning Mode**
  When a mapping that contains a target that has dependent mappings is stopped, the 
  mapping enters the stopping state. It then begins copying all grains that are uniquely held on 
  the target volume of the mapping that is being stopped to the next oldest mapping that is in 
  the copying state. The mapping remains in the stopping state until all grains are copied, and 
  then enters the stopped state. This mode is referred to as the*Cleaning Mode*. 
  
  For example, if the mapping Source-T2 was stopped, the mapping enters the stopping state 
  while the cleaning process copies the data of T2 to T1 (next oldest). After all of the data is 
  copied, Source-T2 mapping enters the stopped state, and T1 is no longer dependent upon 
  T2. However, T0 remains dependent upon T1. 
  
  For example, with Table 11-3 on page 454, if you stop the Source-T2 mapping on “Time 7,” 
  the grains that are not yet copied on T1 are copied from T2 to T1. Reading T1 is then like 
  reading the source at the time T1 was started (“Time 2”). 
  
  As another example, with Table 11-3 on page 454, if you stop the Source-T1 mapping on 
  “Time 8,” the grains that are not yet copied on T0 are copied from T1 to T0. Reading T0 is 
  then like reading the source at the time T0 was started (“Time 0”).
