1. A method for managing a devices in a Storage Area Network, the method comprising:
- obtaining a unique identifier of the device port on a Host Bus Adapter or a storage subsystem which is connected to the fabric port on a Fibre Channel switch when the device port is connected to the fabric port, and each port has a locked flag which value is true or false and each port has a locked identifier;
setting locked flag to false if the locked flag is true at the time the fabric port is designated;
setting locked flag to true if the locked flag is false at the time the fabric port is designated;
setting locked identifier to the identifier of the device port at the time locked flag is set to false from true; and
setting locked identifier to nothing at the time locked flag is set to true from false.

Abstract
In a SAN where a zone has been set through hardware zoning, when any of devices connected to a fabric have been changed, the change is detected. Provided is a method for managing a devices in a Storage Area Network (SAN), each switch in the SAN comprising a memory and a plurality of ports that are connected to a computer and a storage subsystem, the method including obtaining a unique identifier from each of the computer and the storage subsystem connected to the ports, and storing the obtained identifier in the memory.
