+.SS 5. Component activation of VDODataLV
+
+VDODataLV can be activated separately as component LV for examination
+purposes. It activates data LV in read-only mode and cannot be modified.
+If the VDODataLV is active as component, any upper LV using this volume CANNOT
+be activated. User has to deactivate VDODataLV first to continue to use VDOPoolLV.
