Figure 40 Changing into 3DC Multi-target Configuration After Recovering from
Primary Site Failures
Transferring Business Tasks from TCz Secondary Site to the Primary Site (in 3DC Cascading
Configuration)
If you follow the operation procedure in
“Recoverin
g from Failures in the Primary Site and the TCz Synchronous Secondary Site”onpage104 the
system wil
l be changed to 3DC cascading configuration, you can transfer your business tasks back to the
primary si
te after removing failures from the primary site and other locations.
To transfe
r your business tasks back to the primary site, follow the procedure below. Business Continuity
Manager is used in this procedure:
1. Stop business tasks at the TCz Synchronous secondary site.
2. Use Busin
ess Continuity Manager to execute the YKSUSPND FORWARD command to the TCz
Synchronous pair.
NOTE:
YKSUSPND is a command for splitting a pair and stopping the copy operation temporarily.
3. Use the primary volume in the primary site to resume your business tasks.
4. Use Business Continuity Manager to execute the YKRESYNC FORWARD command on the TCz
Synchronous pair, so that the copy direction of the TCz Synchronous pair will be returned to the
original state. The system configuration changes to the original 3DC multi-target configuration.
NOTE:
YKRESYNC is a command for re-establishing a pair.
