Sun Microsystems 3900, 6900 manual Troubleshooting the A4 or B4 FC Link

Troubleshooting the A4 or B4 FC Link

The A4 or B4 link is the FC link from the switch to the Sun StorEdge T3+ array.

If a problem occurs with the A4 or B4 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 an error with the FC link can cause a path to go offline.

FIGURE 5-11and FIGURE 5-12are examples of A4 or B4 Link Notification Events.
