Configuration patterns that allow pair creation
Copy pair creation is allowed in the following cases:
•
When a copy group includes only one consistency group (Business Copy Z/Continuous Access
Synchronous Z/TrueCopy Asynchronous for Mainframe/Continuous Access Journal Z)
•
When copy types are identical within a copy group container (Business Copy Z/Continuous
Access Synchronous Z/TrueCopy Asynchronous for Mainframe/Continuous Access Journal
Z)
•
When there is a Continuous Access Journal Z copy group container with an EXCTG ID
(Continuous Access Journal Z)
Figure 37 (page 73) through Figure 39 (page 74) show each type of configuration.
