You can set the same environment as the production task environment easily by creating replication
volumes using the Data Replication function. You can evaluate an application program by using data
used in the production task, which makes evaluation of application programs more efficient.
Furthermore, in building an evaluation environment, operations are suspended only for the time which
takes to separate replication volumes from the master volume. Therefore, the suspension time can be
substantially reduced.
Figure 1-4 Test Environment Setting
The procedure for using a replication volume as a test environment is described below.
(1) Connect the master volume (MV) and replication volume (RV).
(2) Suspend the production task, separate the replication volume (RV), and then resume the task.
(3) Perform evaluation of the application program by using the separated replication volume (RV).
