BC Z copy group: SIMPLEX
By using copy groups in a 2DC configuration, backups of a large amount of data across multiple
volumes can be acquired remotely without interrupting operation. This allows data to be restored
even if a disaster has affected the primary site.
Creating a Copy Group
The following explains operation procedures based on the copy group operation diagram shown
in
Figure 120 (page 317) . The procedure for making the copy groups is shown in Figure 121 (page
318) . The numbers in the following procedure correspond to those in Figure 121 (page 318) .
To create a copy group is shown in Figure 120 (page 317) .
1. Creating a Cnt Ac-J Z copy group (starting copy group operation).
Load the copy group definitions of Cnt Ac-J Z and BC Z by using the YKLOAD command, and
make sure that the status is SIMPLEX by using the YKQUERY command. Then make a Cnt Ac-J
Z copy group by using the YKMAKE command.
Wait until the status is DUPLEX, by using the YKEWAIT command.
2. Suspending a Cnt Ac-J Z copy group.
Put the Cnt Ac-J Z copy group in the suspend status, by using the YKSUSPND command.
