The Netapp ONTAP special agent crashed with

netapp_ontap.error.NetAppRestError: Caused by HTTPError('400 Client Error: Bad Request for url: https://.../api/storage/shelves?fields=id%2Cfans.id%2Cfans.state%2Cfans.installed'): The value "fans.installed" is invalid for field "fields" (<field,...>)

This occurred because the fans.installed field was not available in some versions of ONTAP. The code now checks the ONTAP version and adjusts the fields requested accordingly.
