Troubleshooting the T1/T2 Data Path
Notes
■There are two T Port links for redundancy.
■If one of the two links is lost, no Sun StorEdge T3+ array LUN failover will occur, and no pathing failures will be noted.
■If both T Port links fail, there will be a Sun StorEdge T3+ array LUN failover, as one of the virtualization engines take control of the I/O operations. One of the Sun StorEdge T3+ array LUNs will failover, as all I/O is routed to the controlling virtualization engine.
■The host will notice a pathing failure in its multipathing software.
