Figure 44 Recovering from Failures in the Primary Site and the TCz Synchronous Secondary Site
Transferring Business Tasks from the URz Secondary Site to the Primary Site
If you follow the instructions in
“Recovering from Failures in the Primary Site and the TCz
Synchronous Secondary Site” (page 90)
and then remove failures from the primary site and the
TCz 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 this procedure, using Business
Continuity Manager:
1.
Use Business Continuity Manager to execute the YKDELETE command on the TCz Synchronous
pair.
NOTE:
YKDELETE is a command for releasing a pair.
2.
Reverse the copy direction of the URz pair. To do this, use the Business Continuity Manager
to execute the YKRESYNC REVERSE command on the journal group corresponding to the URz
pair.
As a result, the former secondary volume in the URz 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
).
NOTE:
YKRESYNC is a command for re-establishing a pair
3.
Stop business tasks at the URz secondary site.
4.
Use Business Continuity Manager to execute the YKSUSPND FORWARD command on the URz
pair.
NOTE:
YKSUSPND is a command for splitting a pair and stopping the copy operation
temporarily.
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
URz 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 on the TCz pair.
The system configuration returns to the original 3DC multi-target configuration (see the
lower-right picture in
).
