Do you want to enable coupling facility duplexing for the Parallel Sysplex?

To enable coupling facility duplexing for the sysplex, you must ensure that all systems in the sysplex are at z/OS Version 1 Release 2 or higher.

Specify Yes if you want to enable coupling facility duplexing for the Parallel Sysplex. On the add or edit a coupling facility structure panel of the wizard, you can select which structures you want to duplex.

Specify No if you do not want to create new CFRM couple data sets with the duplexing option. If you specify No, coupling facility duplexing is not enabled for structures. The following message also appears in the CFRM couple data set table:
