Apparatus and method for preventing disruption of fibre channel fabrics caused by reconfigure fabric (rcf) messages

Apparatus and method for claimed is a preventing structure and RCF (41-44) to make the optical fibre channel structure of be. The device comprises storage area network and device of optical fibre channel switching in structure. Each of the plurality of switching a selectively producing port one to reject or the RCF logic message. Which is configured to reject the RCF message, wherein the RCF message the port to generate with the code to explain of the E-SHAPED port is isolated of the rejection message, a conversion into the isolation of. For generating message RCF the plate receiving rejection message, wherein port is converting into the isolation of. To a method of this invention, the storage service provider or the is a through a command line interpreter or a management accessing application structure of switch. Once is arranged to structure, access switch the logic of a port and upper of electrical for configuring is rejected or the lug RCF message.
