The snapmirror quiesce command waits for all volume and qtree SnapMirror transfers to complete, and blocks any further updates. If a qtree is not in a stable state (is in transition), the snapmirror quiesce command forces it into a stable state.
You can quiesce only volumes and qtrees that are online and that are SnapMirror destinations. You cannot quiesce a restricted or offline volume or a qtree in a restricted or offline volume.
The snapmirror quiesce command stops a volume or qtree from acting as a SnapMirror destination, but does not prevent it from acting as a SnapMirror source.
