Transferring Business Tasks from TCz Secondary Site to the Primary Site (in 3DC Multi-target
Configuration)
If you remove 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 this procedure, using Business
Continuity Manager:
1. Use Business Continuity Manager to execute the YKDELETE command on the current URz pair,
which extends between the TCz secondary site and the URz secondary site.
NOTE: YKDELETE is a command for releasing a pair.
2. Stop business tasks at the TCz Synchronous secondary site.
3. Use Business Continuity Manager to execute the YKSUSPND FORWARD command on the TCz
Synchronous pair.
NOTE: YKSUSPND is a command for splitting a pair and stopping the copy operation
temporarily.
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 on the TCz
Synchronous pair, so that the copy direction of the pair will be returned to its original direction.
NOTE: YKRESYNC is a command for re-establishing a pair.
6. Create a URz pair that consists of a volume in the primary site and a volume in the URz
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 URz
secondary site.
To create this pair, use Business Continuity Manager to execute the YKMAKE command on
the journal group corresponding to that pair.
