[Execution Conditions]
To perform operations regarding the Copy Control state, the following conditions must be satisfied.
(i) The target MV and RV are paired.
(ii) The target MV or RV has been registered in the volume list.
(iii) The volume list is not being created or updated.
(iv) The disk array where the specified MV and RV are stored is not in the Freeze state.
(v) The Activity State of the target pair is Replicate or Restore.
(vi) The Semi-synchronous Copy mode cannot be specified for paired volumes set in the same disk
array. The Semi-synchronous Copy mode can be specified only for paired volumes set in
different disk arrays.
(vii) Changing from Synchronous Copy to Semi-synchronous Copy mode or from Semi-synchronous
Copy to Synchronous Copy mode is disabled.
(viii) Specifying a volume of a dynamic disk or a GPT-format partition disk is not allowed (Windows
only).
(ix) The iSM dedicated special file is not being created (HP-UX version UNIX only).
(x) When an LVM volume group or a VxVM disk group is specified, the target volume group or disk
group must be active (UNIX only).
(xi) When specifying the combination of an LVM volume group or a VxVM disk group with a special
file name (logical disk name), you must specify the same number of logical volumes that make up
the volume group or disk group as MV (RV) on the special file name (logical disk name) side.
In this case, Copy is performed in specified sequential order (UNIX only).
The above execution conditions (ii), (iii), (viii), (ix), (x), and (xi) are not applicable when conducting a
joint operation with the iSM (replication management).
