> Note At least one valid DCNM license must be provisioned before adding SMI-S storage discovery datasources.

> 4. Specify the SMI-S Server IP, User Name and Password.
> 5. Specify the Name Space and Interop Name Space.
> 6. By default, the Port number is pre-populated. If you select the Secure checkbox, then the default secure port number is populated.

> When using the Secure mode with EMC, the default setting is mutual authentication. For more information, see EMC’s documentation about adding an SSL certificate to their trust store, or set SSLClientAuthentication value to ‘None’ in the Security_Settings.xml config file and then restart the ECOM service.
