Port Grouping policy

FIGURE 3 Port grouping behavior
When a dual redundant fabric configuration is used, internal ports (F_Ports) connected to a FC SAN
Module can access the same target devices from both of the fabrics. In this case, you must group
the external ports (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.
Refer to Figure 4.
FIGURE 4 Port group 1 (pg1) setup
Adding an external port (N_Port) to a port group
1. Connect to the FC SAN Module and log in using an account assigned to the admin role.
2. Enter the ag --pgadd command with the appropriate operands to add an external port
(N_Port) to a specific port group. In the following example external port 14 is added to port
group 3.
Note that if you add more than one external ports, you must separate them with a semicolon.
