Continuous Access Asynchronous for Mainframe (Cnt Ac-A)

Stores data and control information for each P-VOL in a sidefile, and performs and manages the

remote copying of volumes independently (asynchronously) of the host I/O processes.

Writes updated data and control information to the master journal on the primary site. When the

secondary site makes a read journal request, the updated data and control information are written

from the master journal to the restore journal (on the secondary site). This activity is performed

asynchronously to host I/O processing.
