FIGURE 6 Port grouping behavior
When a dual redundant fabric configuration is used, F_Ports connected to a switch in AG mode can
access the same target devices from both of the fabrics. In this case, you must group the N_Ports
connected to the redundant fabric into a single port group. It is recommended to have paths fail
over to the redundant fabric when the primary fabric goes down.
FIGURE 7 pg1 setup
ATTENTION
If N_Ports are connected to unrelated fabrics are grouped together, N_Port failover within a port
group can cause the F_Ports to connect to a different fabric and the F_Ports may lose connectivity
to the targets they were connected to before the failover, thus causing I/O disruption as shown in
Figure 7.
