Consistency is preserved for copy group containers with an EXCTG ID specified.

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/TrueCopy Asynchronous for Mainframe/Continuous Access Journal
Z)

1

When copy types are different within a copy group container (Continuous Access Synchronous
Z/TrueCopy Asynchronous for Mainframe/Continuous Access Journal Z)

When copy groups contain some consistency group volumes (Business Copy Z/Continuous
Access Synchronous Z/TrueCopy Asynchronous for Mainframe/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/TrueCopy
Asynchronous for Mainframe/Continuous Access Journal Z)

Figure 38 (page 73)

Figure 40 (page 74)

show the configurations in which copy pair

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.
