For changing the Copy Control state, the iSMrc_change command is used.
You can use option specification of the iSMrc_change command to perform the Copy Control state
change in the Replicate or Restore state.
Before the Copy Control state is changed, 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).
When RV Restore(protect) specified is executed, the updated data of the MV is not reflected into the
RV. Therefore, changing a Copy Control state (Synchronous Copy Mode, Semi-synchronous Copy
Mode, or Background Copy) has no effect.
[Main Options]
For iSMrc_change command, you can specify the following options for changing the Copy Control
state.
(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”.
(2) Copy Control State
The following Copy Control State can be specified.
y Synchronous Copy (-sync)
Changes the Copy Control state to the Synchronous Copy mode.
y Semi-synchronous Copy (-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 (-bg)
Changes the Copy Control state to the Background Copy state.
y Suspend (-suspend)
Changes the Copy Control state to the Suspend state.
y Resume (-resume)
Changes the Copy Control state to the Foreground Copy state.
The following table shows the Copy Control state before and after the change is made.
