Figure 40 Recovering from Failures in the Primary Site and the TrueCopy for Mainframe Synchronous
Secondary Site
Transferring Business Tasks from the Universal Replicator for Mainframe Secondary Site to the
Primary Site
If you follow the instructions in the previous section and then remove failures from the primary site
and the TrueCopy for Mainframe Synchronous secondary site, 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 TrueCopy for Mainframe Synchronous pair.
2.
Reverse the copy direction of the Universal Replicator for Mainframe pair. To do this, use
Business Continuity Manager to execute the YKRESYNC REVERSE command (a command for
re-establishing a pair) on the journal group corresponding to the Universal Replicator for
Mainframe pair.
As a result, the former secondary volume in the Universal Replicator for Mainframe secondary
site changes to the primary data volume. Also, the former primary volume in the primary site
changes to the secondary data volume (see the upper-right picture in
).
3.
Stop the business tasks at the Universal Replicator for Mainframe secondary site.
4.
Use Business Continuity Manager to execute the YKSUSPND FORWARD command (a command
for splitting a pair and stopping the copy operation temporarily) on the Universal Replicator
for Mainframe pair.
5.
Use the primary volume in the primary site to resume your business tasks.
6.
Use Business Continuity Manager to execute the YKRESYNC FORWARD command on the
Universal Replicator for Mainframe pair, so that the copy direction of the pair will be returned
to its original direction.
7.
Use Business Continuity Manager to execute the YKMAKE command (a command for creating
a pair) on the TrueCopy for Mainframe pair.
The system configuration returns to the original 3DC multi-target configuration (see the
lower-right picture in
).
