Figure 43 Transferring Business Tasks from the TCz Secondary Site to the Primary Site (When Delta
Resync Operation is Performed in 3DC Multi-target Configuration)
Recovering from Failures in the Primary Site and the TCz Synchronous Secondary Site
If a disaster or failure occurs in both the primary site and the TCz Synchronous secondary site in
a 3DC multi-target configuration, you can resume your business tasks by using the secondary
volume in the URz secondary site. After you transfer business tasks to the URz secondary site, you
need to remove failures from the primary site and the TCz Synchronous secondary site, so that you
will be able to transfer business tasks back to the primary site.
To transfer your business tasks to the URz secondary site, follow this procedure, using Business
Continuity Manager:
1. Use Business Continuity Manager to execute the YKSUSPND REVERSE command on the journal
group corresponding to the URz pair, which extends between the primary site and the URz
secondary site.
NOTE: YKSUSPND is a command for splitting a pair and stopping the copy operation
temporarily.
2. Use volumes in the URz primary site to resume your business tasks.
