3Par V400 node master election, how does it work?

Anyone here that is deep on the master election process of a four node V400?
Usually the first node that boots is the master of the 4-node cluster, but what if it fails, which node will then become the master? (it should be one of the nodes of the other node-pair)
Is my assumption correct that the two nodepairs together form a majority nodeset cluster?
any insight would be welcome. Also a pointer to some documentation on this highly technical subject would be appreciated.
