For Restore, the iSMrc_restore command is used.
By executing the iSMrc_restore command, copy from RV to the paired MV starts.
Before Restore is performed, MV and RV to be specified must be paired beforehand. In addition, MV
and RV to be specified must be registered in the volume list (created by iSMvollist) beforehand.
If RV is used as a file system, the mount of the file system must be canceled before Restore is started.
On the Windows system, unmount the MV and flush the buffer of the file system. Then, mount the
MV again after starting Restore. On the UNIX system, if an MV’s file system is mounted, Restore
does not start resulting in an abnormal end. Therefore, before executing Restore, you must unmount
the MV’s file system.
[Main Options]
For the iSMrc_restore command, you can specify the following options regarding the Restore
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 about 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)
Normally, only the difference area (diff) of MV and RV is copied. You can also instruct to copy
the entire area (full) explicitly.
