Operating ReplicationControl together with the replication management function of the iSM enables
you to operate and maintain the data replication function, and to construct the environment, such as
pairing and unpairing by commands, which have been conventionally conducted by the client of the
iSM through GUI.
You do not need to connect the logical disk to be operated to the server and to register the logical disk
in the volume list. Therefore, to link with the iSM for operation, you do not need to create the volume
list.
To conduct a joint operation with the iSM, install the ReplicationControl on the server on which the
iSM has been installed and is operating. When you conduct ReplicationControl environment setting,
select MANAGER (issuing an I/O to a disk array via the iSM) for the setting of I/O issuing path to the
disk array. For details of the environment setting, refer to Chapter 3 “Operation Settings” in the “Data
Replication Command Reference”.
Operations linked with the iSM have the following advantages.
y You can use commands for managing and maintaining the operations of the data replication function
and operating environment construction.
y The logical disk to be operated does not need to be connected to a server. You can operate all the
logical disks in the disk array to be monitored by the iSM.
y Since operation is performed through the iSM, connection to the disk array and issuing an I/O to the
disk array can be performed through LAN.
