(3) Specifying the Copy Control state (-cpmode)
You can specify the Copy Control state in Restore Execution and the Synchronous state.
y Synchronous Copy (-cpmode sync)
Changes the Copy Control state to the Synchronous Copy mode.
y Semi-synchronous Copy (-cpmode semi)
Changes the Copy Control state to the Semi-synchronous Copy mode. This can be specified
for paired volumes in different disk arrays.
y Background Copy (-cpmode bg)
Changes the Copy Control state to the Background Copy state.
(4) Specifying the access restrictions for RV (-rvacc)
You can specify the access restrictions for RV in Restore Execution or when Restore is complete.
y Not Ready (-rvacc nr)
Switches to the Not Ready state. Operations cannot be performed for the volume from the
system.
y Read Only (-rvacc ro)
For the volume, only Read from the system can be performed.
Pay careful attention when you specify Ready Only (-rvacc ro) for the RV access restrictions.
For details, refer to 2.6 “RV Access Restriction”.
(5) Specifying the wait for copy completion (-wait/nowait)
The system can wait for completion of the command after Restore until the Synchronous state.
y Wait Specified (-wait [second])
If a value is specified in second, the monitoring time interval of the disk array becomes the
specified value. The available range is from 1 through 30 seconds (integer). If the value is
omitted, the RPL_WATCHDEV setting in the replication operation option setting file is used
for Windows while the setting of environment variable RPL_WATCHDEV is used for UNIX.
For details on operational settings, refer to the “Data Replication Command Reference”.
y No Wait (-nowait)
Performs only a Restore start instruction and terminates the command. You can check the
termination of Restore by the iSMrc_query or iSMrc_wait command.
(6) Specifying an operation mode for RV (-mode)
You can select whether to reflect the updated data of the MV into the RV while performing
Restore.
y RV update specified (-mode update)
Performs Restore while reflecting the updated data of the MV into the RV. When Restore is
completed and the Synchronous State is placed, the state changes to Synchronous State
(rst/sync).
