Has same issue in my lab environment. If you check kamino.log (C:\Program Files\NetApp\Virtual Storage Console\log) you should be able to find line similar to this (search for "not yet been fully discoverred" string)
Controller: 8fbef3a5-b2e8-11e5-84dc-0050569634b4(addr=192.168.2.70:443, user=admin) has not yet been fully discovered by Kamino.
The reason why it's not fully discovered is (from the same kamino.log file)
TRACE [RawHttpZAPIInvoker] - Calling zapi on 192.168.2.70:443, secure=true, useTLS=true DEBUG [ZAPIInvoker] - retryIfApplicable: message=netapp.manage.NaAPIFailedException: Server chose TLSv1, but that protocol version is not enabled or not supported by the client.
