For Replicate, the iSMrc_replicate command is used.
By executing the iSMrc_replicate command, copy from MV to the paired RV starts.
Before Replicate is performed, MV and RV to be specified must be paired beforehand. In addition,
the MV must be registered in the volume list (created by iSMvollist).
If MV and RV are used as file systems, the mount of the file systems must be canceled.
[Main Options]
For the iSMrc_replicate command, you can specify the following options regarding the Replicate
operation.
(1) Specifying paired volumes
Specify MV and RV volumes.
y Specify MV (-mv volume -mvflg mv_flg)
Specifies the volume and volume type of MV.
y Specify RV (-rv volume -rvflg rv_flg)
Specifies the volume and volume type of RV.
For information on volume types, refer to 4.3 “Volume Types”.
On the Windows system, when a specific partition (drive letter) is specified for a volume
consisting of multiple partitions, all partitions in the volume become operation targets; therefore,
the default setting does not allow the multiple partitions to be operated. To perform operations
for a volume consisting of multiple partitions, you need to change the default setting. For
information about the replication operation option setting file, refer to the “Data Replication
Command Reference”.
(2) Specifying the copy range (-cprange)
By default, only the difference area (diff) of MV and RV is copied. You can also instruct to
copy the entire area (full) explicitly.
