Figure 38 Transferring Business Tasks from the TrueCopy for Mainframe Secondary Site to the
Primary Site (in a 3DC Multi-target Configuration)
Transferring Business Tasks from TrueCopy for Mainframe Secondary Site to the Primary Site (When
the Delta Resync Operation is Performed in 3DC Multi-target Configuration)
If you remove the failures from the primary site and other locations, and then the system is changed
to 3DC multi-target configuration, you can transfer your business tasks back to the primary site.
To transfer your business tasks back to the primary site, follow the procedure below. Business
Continuity Manager is used in this procedure:
1. When the Universal Replicator for Mainframe pair is in Duplex status, use Business Continuity
Manager to execute the YKSUSPEND Flash FORWARD command on the Universal Replicator
for Mainframe pair.
2. Use Business Continuity Manager to execute the YKRESYNC REVERSE command on the current
TrueCopy for Mainframe Synchronous pair.
The copy direction of the TrueCopy for Mainframe Synchronous pair will be reversed.
3. Stop all business tasks at the TrueCopy for Mainframe Synchronous secondary site.
4. Use Business Continuity Manager to execute the YKSUSPND FORWARD command on the
TrueCopy for Mainframe Synchronous pair.
The TrueCopy for Mainframe Synchronous pair is then split, and the copy operation stops
temporarily.
5. Use the main volume in the primary site to resume your business tasks.
6. Use Business Continuity Manager to execute the YKRESYNC FORWARD command on the
TrueCopy for Mainframe Synchronous pair.
The copy direction of the pair is then returned to its original direction.
7. Perform the delta resync operation on the volume in the TrueCopy for Mainframe Synchronous
primary site.
The status of the data volumes of the Universal Replicator for Mainframe pair changes as
explained in the following table.
