Chapter 3 Troubleshooting the Fibre Channel Links 35
For Internal Use Only
A3/B3 Fibre Channel (FC) Link
If a problem occurs with the A3/B3 FC link:
■ In a Sun StorEdge 3900 series system, the Sun StorEdge T3+ array will fail over.
■ In a Sun StorEdge 6900 series system, no Sun StorEdge T3+ array will fail over,
but a severe problem can cause a path to go offline.
FIGURE 3-6, FIGURE 3-7, and FIGURE 3-8 are examples of A3/B3 FC link Notification
