6.Create a URz pair that consists of a volume in the primary site and a volume in the URz secondary site. Ensure that the primary data volume of the resulting pair is the volume in the primary site, and that the secondary data volume of the resulting pair is the volume in the URz secondary site.
To create this pair, use Business Continuity Manager to execute the YKMAKE command on the journal group corresponding to that pair.
When the pair is created, the system configuration returns to the original 3DC
Note: YKMAKE is a command for establishing a pair.
