(3) Specifying the Copy Control state (-cpmode)
You can specify the Copy Control state during Replicate execution or in the Synchronous state.
The following can be specified.
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
pairs in different disk arrays.
y Background Copy (-cpmode bg)
Changes the Copy Control state to the Background Copy state.
(4) Specifying the access restrictions to RV (-rvacc)
You can specify the access restrictions to RV in Replicate Execution or when Replicate is
complete.
y Not Ready (-rvacc nr)
Switches to the Not Ready state. Operations cannot be performed from the system.
y Read Only (-rvacc ro)
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 the completion of the command after Replicate has been performed until
the Synchronous state starts.
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 Replicate start instruction and terminates the command. You can check the
termination of the command by the iSMrc_query or iSMrc_wait command.
