Changing a copy type of a Consistency Group from GM to MM
This procedure uses the GUI to change an existing Consistency Group from Global Mirror to
Metro Mirror. (Note that you can use the same procedure to change the Consistency Group
from MM to GM or from GM to GM Cycling Mode.)
As the first action, you need to stop the Consistency Group. Click Stop from the Actions
drop-down menu (Figure 9-124).
Figure 9-124 Stop the Consistency Group
After the stopping the relationship, from the same Actions drop-down menu, click Edit
Relationship asshownin Figure 9-125.
