Supporting a Continuous Access Journal for Mainframe copy group configuration

To create an inter-control unit logical path dedicated to the command device:
1. Establish an inter-control unit logical path.
This inter-control unit logical path must be assigned a port number that is different from the
port number of the inter-disk controller logical path to be used by the Continuous Access
Journal for Mainframe copy group.
2. Create a command device on the CU with which the inter-control unit logical path has been
established.
You can create a command device on the CU that contains the Continuous Access Journal for
Mainframe copy group.

Preparing to use the Remote DKC Control function

Before using the Remote DKC Control Function:
1. Place all command devices offline.
2. Execute the YKLOAD command.
From the ISPF panel or in a script, execute the YKLOAD command with the DAD and ROUTE
parameters specified.
Configuration definition for using the Continuous Access Synchronous
Consistency Preservation function
To use the Continuous Access Synchronous consistency preservation function, you must define, at
the site at which a copy operation will be performed, command devices and a route (only the
starting point) that defines those command devices.
If you use the Continuous Access Synchronous consistency preservation function from the secondary
site, you need to define, at the secondary site, command devices and a route (only the starting
point) that defines those command devices.
