Sun Microsystems 3900, 6900 manual Troubleshooting the T1 or T2 Data Path

Troubleshooting the T1 or T2 Data Path

When you are troubleshooting the T1 or T2 data path, note the following:

■Two T port links provide redundancy.

■If one of the two links is lost, no Sun StorEdge T3+ array LUN failover occurs and no pathing failures are detected.

■If both T port links fail, a Sun StorEdge T3+ array LUN failover occurs, as one of the virtualization engines takes control of the I/O operations. One of the Sun StorEdge T3+ array LUNs fail over, as all I/O is routed to the controlling virtualization engine.

■The host detects a pathing failure in its multipathing software.
