A Fibre Channel port group is a group of one or more Fibre Channel ports. Fibre Channel port groups help you organize and manage LUN mappings more easily. When a LUN is mapped to a Fibre Channel port group, QTS automatically maps the LUN to every Fibre Channel port in the group.
Each Fibre Channel port can be in one or more Fibre Channel port groups.
Each LUN can only be mapped to one Fibre Chanel group.
There is a default port group that contains all Fibre Channel ports.
