90 Sun StorEdge 3900 and 6900 Series Troubleshooting Guide — March 2002
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 ).
