Figure 39 Transferring Business Tasks from the TrueCopy for Mainframe Secondary Site to the
Primary Site (When the Delta Resync Operation is Performed in 3DC Multi-target Configuration)
Recovering from Failures in the Primary Site and the TrueCopy for Mainframe Synchronous Secondary
Site
If a disaster or failure occurs in both the primary site and the TrueCopy for Mainframe Synchronous
secondary site in a 3DC multi-target configuration, you can resume your business tasks by using
the secondary volume in the Universal Replicator for Mainframe secondary site. After you transfer
the business tasks to the Universal Replicator for Mainframe secondary site, you need to remove
failures from the primary site and the TrueCopy for Mainframe Synchronous secondary site, so
that you will be able to transfer the business tasks back to the primary site.
To transfer your business tasks to the Universal Replicator for Mainframe secondary site, follow the
procedure below. Business Continuity Manager is used in this procedure.
1. Use Business Continuity Manager to execute the YKSUSPND REVERSE command (a command
for splitting a pair and stopping the copy operation temporarily) on the journal group
corresponding to the Universal Replicator for Mainframe pair, which extends between the
primary site and the Universal Replicator for Mainframe secondary site.
2. Use volumes in the Universal Replicator for Mainframe primary site to resume your business
tasks.
