text: A**stop**command takes the relationship to the ConsistentStopped state. A**stop**command 
  with the**-access**parameter takes the relationship to the Idling state. 
  
  A**switch**command leaves the relationship in the ConsistentSynchronized state, but it 
  reverses the master and auxiliary roles (it switches the direction of replicating data). A**start**
  command is accepted, but has no effect. 
  
  If the relationship or Consistency Group becomes disconnected, the same changes are made 
  as for ConsistentStopped. 
  
  **Idling**
  Idling is a connected state. Both master and auxiliary volumes operate in the master role. 
  Therefore, both master and auxiliary volumes are accessible for write I/O. 
  
  In this state, the relationship or Consistency Group accepts a**start**command. MM/GM 
  maintains a record of regions on each disk that received write I/O while they were idling. This 
  record is used to determine what areas must be copied following a**start**command. 
  
  The**start**command must specify the new copy direction. A**start**command can cause a 
  loss of consistency if either Volume in any relationship received write I/O, which is indicated 
  by the Synchronized status. If the**start**command leads to loss of consistency, you must 
  specify the**-force**parameter.
