  **11.9.10 Switching a relationship copy direction**
  
  When a remote copy relationship is in the Consistent synchronized state, the copy direction 
  for the relationship can be changed. Only relationships that are not a member of a 
  Consistency Group, or the only relationship in a Consistency Group, can be switched. In any 
  other case, consider switching the Consistency Group instead. 
  
  **Important:**When the copy direction is switched, it is crucial that no outstanding I/O exists 
  to the volume that changes from primary to secondary because all of the I/O is inhibited to 
  that volume when it becomes the secondary. Therefore, careful planning is required before 
  you switch the copy direction for a relationship. 
  
  To switch the direction of a remote copy relationship, complete the following steps: 
  1. Open the**Copy Services**→ →**Remote Copy**panel. 
  
  2. Right-click the relationship to be switched and select**Switch**, as shown in Figure 11-141.
