102 Sun StorEdge 3900 and 6900 Series Troubleshooting Guide • March 2002
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.
