The change of the device will not affect the zoning configuration. This zone allows the devices connected to the ports to communicate with each other. Both of them are all controlled by chips now. Now they call Domain ID or port based zone as hard zone, and the WWN based zone as soft zone. The difference is, the hard zone is implemented by the chip, while the soft zone is implemented by the software. The switch vendors used to define two kinds of zones, the hard zone and soft zone. If the device does not belong to this zone, it could not communicate with the devices in this zone. Once a zone is configured, only the devices in this zone can talk with each other. By adding the specific devices to a zone, the administrator can allow the devices to communicate with each other. Zone is a logical configuration on FC-SAN switches.
