Cancelling VSWCTRL1 causes only the failover to VSWCTRL2. The physical OSA being used remains. I.e. QUERY VSWITCH should just show a new controller. No change in OSA addresses.

The VSWITCH protects you from an adapter/switch failure. > Is it older technology, that got replaced by vswitch? Routed Guest LAN and p2p connections were replaced by a switched Guest LAN. > Is it a LPAR type technology, for those that don't have VM? No. z/VM only.
