I do not see why you'd pay license for a turned off node. If you start using it, then yes, you should pay license for, but as long as the node is down I would think there is no need for additional license.

Also, if you loose one of the other nodes you've already paid for and bring up the "standby" node I think you should be alright as you are not using more capacity than you paid for at any given time.

Anyway, that's my two cents, but to be sure of what is legal and so on you should talk to your rep.
