For direct operation for a disk array, you can select one of the following configurations for each server.
y
Direct operation is the most basic operation when the replication operation is performed from a
business server.
The MV used for operations is connected to a business server, and the RV used for backup and the
like is connected to a backup server or others. To perform direct operation, you need to register the
logical disk that is recognized by a server (OS) and can be accessed in the volume list on each server.
