3. Because the master-auxiliary re lationship direction is reversed, write access is disabled 
on the new auxiliary volume (former master volume), whereas it is enabled on the new 
master volume (former auxiliary volume). A warning message is displayed, as shown in 
Figure 11-142. Click Yes.

4. When a remote copy relationship is switched, an icon is displayed in the Remote Copy 
panel list, as shown in Figure 11-143.

11.9.11  Switching a Consistency Group direction
When a remote copy consistency group is in the consistent synchronized state, the copy 
direction for the consistency group can be changed.
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.
