Deleting an external port (N_Port) from a port group

Before deleting an external port (N_Port), all internal ports (F_Ports) mapped to that external port
must be remapped before that external port is deleted from a port group.
If an external port is deleted from a port group enabled for Login Balancing, the internal ports
mapped to that external port stay with the port group as long as there are other external ports in
the group. Only the external port is removed from the port group. This is because the internal ports
are logically associated with the port groups that are enabled for Login Balancing. This is not the
case for port groups not enabled for Login Balancing. When you delete an external port from one of
these port groups, the internal port that are mapped to the external port move to PG0 along with
the external port. This is because the internal ports are logically associated with the external ports
in port groups not enabled for Login Balancing.
