UCS Manager does not allow to update a service profile if it bound to a Service Profile Template. The UCSM Driver does not handle such case. The driver does not add vlan to an interface and it does not inform that it was not added. Actually. it says "an entry that already exists" (see log below) but the entry does not exist and it could not be added due to UCSM restriction.
Expected behavior: The UCSM Driver check if it possbile to update service profile during initialization phase (right after the neutron service is started)
