.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.
