[Discovery-NetApp] Difference in serial number passed to payload than what is in pattern designer. Example NetApp storage node serial number

Difference in serial number passed to payload than what is in pattern designer.  Causing the below issue:
1. NetApp storage discovery is updating the part_number type serial number on the node CI where as we expect to have cim_chassis

Actual:
Check cmdb_ci_storage_node_element table element contians part_number type serial number.

Expected:
Check cmdb_ci_storage_node_element table element contians cim_chassis type serial number.

8.Navigate to cmdb_serial_number table.
9.Click on Configuration item column field and Paste name copied in step 6.
