43 Transferring Business Tasks from the TCz Secondary Site to the Primary Site
(When D
elta 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 the procedure below. Business Continuity
Manager is used in this procedure:
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. Usevolumes in theURz primarysite toresumeyourbusinesstasks.
