Failback policy

3. The host establishes a new connection with the fabric.

Example: Failback Policy

In Example 3, the Brocade Access Gateway N_1 remains disabled because the corresponding F_A1

port is offline. However N_2 comes back online. (See Figure 1-5 for the original failover scenario.)

The ports mapped to N_1 (F_1 and F_2) continue to be routed to N_3; the ports originally mapped to

N_2 (F_3 and F_4) are disabled, rerouted to N_2, and then enabled.
