To perform operations of suspending/resuming copy, the following conditions must be satisfied.

(ii) The target MV and RV are paired.
(iii) The activity state of the target pair is Replicate or Restore.
(iv) The Semi-synchronous Copy mode cannot be specified for pairs set in the same disk array.
The Semi-synchronous Copy mode can be specified only for pairs set in different disk arrays. (Can
be set only when copy is resumed.)
(v) The disk array where the specified MV and RV are stored is not in the Freeze state.
(vi) The disk array where the specified MV and RV are stored is monitored.
(In case of copy suspend, MV must be monitored)
(vii) The specified MV is not registered in the AT-group.
Figure 3-25 illustrates the execution conditions of operations of suspending/resuming copy. (Each of
