Changing to 3DC Multi-target Configuration after Recovering from Primary Site Failures
If you follow the operation procedure in section 3.8.6.5 and then the system does not change to 3DC
cascading configuration, you can change the system into 3DC multi-target configuration after removing
failures from the primary site and other locations, The resulting 3DC multi-target system uses the former
TCz secondary volume as a primary volume.
To change the system into 3DC multi-target configuration:
• Use Business Continuity Manager to execute the YKDELETE command on the journal group
corresponding to the former URz pair.
