Likely key of CIM property for volumes of your storage distinguish from VolumeName. In order to find out this key, try run new script storage_cim_print.py for view CIM properties of your storage. Then search your logical volumes names (values) and determine key for this.

Changed the value of 'VolumeName' to 'ElementName' and it worked. The script does not crash. Thanks.
