Specify Yes to define options for duplexing or No for no duplexing.
Duplexing allows you to create copies of the logstreams on DASD.
If you do not specify duplexing, log data for a coupling facility log stream will not be duplexed. A copy of the coupling facility log stream data is maintained in local storage buffers on each system.If you specify duplexing, a copy of the coupling facility log stream data is maintained in DASD staging data sets, one per log stream on a system. If you specify Yes, the plug-in displays the specify duplexing options panel when you click Next.
