Sun Microsystems 3900 Series manual 2Sun StorEdge 6900 Series Logical View

In the event of a path failure after the second tier of Sun StorEdge network FC switch-8 and switch-16 switches (or in the event of both T Ports failing between the switches), the virtualization engines force a LUN failover of the affected Sun StorEdge T3+ array and routes all I/O to its secondary path. From the host side, nothing has changed; all I/O is routed through both HBAs (refer to FIGURE 7-6).
