Chapter 2 Operation and Maintenance

By using the Separate function which enables the use of RV also in the middle of separation while
reflecting the difference of MV and RV, it is not necessary to wait for the copy operation to finish,
thereby reducing the time duration when the master operations are halted. Also, it is possible to refer
to the replication volume for the latest data, thereby reducing the time duration when the server-side
operations are halted.
In this example, replication volume building is explained by assuming that the volumes have been set as
a pair and operation has started using the business server, the pair is separated, and the MV drive letter
is G and the RV drive letter is H.
Before starting replication operations, prepare the target volumes beforehand.
For more information on how to prepare volumes, refer to 1.7 “Preparing Volume”.
