Configuration Patterns that Prohibit Pair Creation

Copy pair creation is prohibited in the following cases:
When the capacities of the P-VOL and S-VOL are different (Business Copy Z/Continuous
Access Synchronous Z/Continuous Access Asynchronous/Continuous Access Journal Z)
When copy types are different within a copy group container (Continuous Access Synchronous
Z/Continuous Access Asynchronous/Continuous Access Journal Z)
When copy groups contain some consistency group volumes (Business Copy Z/Continuous
Access Synchronous Z/Continuous Access Asynchronous/Continuous Access Journal Z)
When a copy group contains both a consistency group and copy pairs that are not in the
consistency group (Business Copy Z/Continuous Access Synchronous Z/Continuous Access
Asynchronous/Continuous Access Journal Z)

creation is not allowed.
1. If you want to perform a migration, creation of a copy pair where the capacity of the S-VOL is larger than that of the
P-VOL might be allowed. For details, see the guide of the corresponding program.
