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”.
