Not sure what you mean. Shall the second machine take over? Since this
should be hot 2 hours is a lot of time. Using a private network you can
detect failures almost immediately.
I do recommend a a local checking like watchdog or mon, so a restart is
tried before the takeover. And I'd make sure the primary machine stays
down.
Has been done before. :-)
