If a controller pair is in transparent failover mode and the port 1 link is separate from
the port 2 link (that is, ports 1 of both controllers are on one loop or fabric, and port 2
of both controllers are on another), each adapter will have one connection, as shown in
Figure 18.
If a controller pair is in transparent failover mode and port 1 and port 2 are on the same
link (that is, all ports are on the same loop or fabric), each adapter will have two
connections, as shown in Figure 19.
