To define a 2DC configuration with HyperSwap and Continuous Access Journal for Mainframe,
create a PPRC copy pair for which HyperSwaps are enabled. Next, in Business Continuity Manager,
define that copy pair as a Continuous Access Synchronous for Mainframe copy pair with the
HyperSwap attribute. Also, create a Continuous Access Journal for Mainframe copy pair between
the primary storage system and remote storage system, and then create a Continuous Access
Journal for Mainframe copy pair in the delta-resync standby status between the local storage system
and remote storage system. If a copy pair is a Continuous Access Synchronous for Mainframe
copy pair with the HyperSwap attribute, the only operations that Business Continuity Manager can
perform on it are monitoring or dissolving it.
Figure 19 (page 49) and Figure 20 (page 49) show a 2DC configuration before and after a
HyperSwap is performed.
