Figure 37 Transferring Business Tasks from the TrueCopy for Mainframe Secondary Site to the
Primary Site (in a 3DC Cascading Configuration)

Transferring Business Tasks from the TrueCopy for Mainframe Secondary Site to the Primary Site
(in a 3DC Multi-target Configuration)

If you remove failures from the primary site and other locations and then the system is changed to
a 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.

Use Business Continuity Manager to execute the YKDELETE command (a command for releasing
a pair) on the current Universal Replicator for Mainframe pair, which extends between the
TrueCopy for Mainframe secondary site and the Universal Replicator for Mainframe secondary
site.

2.

Stop business tasks at the TrueCopy for Mainframe Synchronous secondary site.

3.

Use Business Continuity Manager to execute the YKSUSPND FORWARD command (a command
for splitting a pair and stopping the copy operation temporarily) on the TrueCopy for Mainframe
Synchronous pair.

4.

Use the main volume in the primary site to resume your business tasks.

5.

Use Business Continuity Manager to execute the YKRESYNC FORWARD command (a command
for re-establishing a pair) on the TrueCopy for Mainframe Synchronous pair, so that the copy
direction of the pair will be returned to its original direction.

6.

Create a Universal Replicator for Mainframe pair that consists of a volume in the primary site
and a volume in the Universal Replicator for Mainframe 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 Universal Replicator for Mainframe secondary
site.

To create this pair, use Business Continuity Manager to execute the YKMAKE command (a
command for establishing a pair) on the journal group corresponding to that pair.

When the pair is created, the system configuration returns to the original 3DC multi-target
configuration.
