Abstract: The present invention relates to a method, a computer program product and a system for managing virtual instances of a physical port attached to a network. In a preferred embodiment of the invention the method is based on t he Fibre Channel N Port virtualisation for a physical Fibre Channel N Port. Multiple virtual Fibre Channel adapters share a single physical N Port among multiple operating system instances. The invention discloses means for the automatic and persistent generation and administration of unique Worldwide Port Names needed for the N Port virtualisation.

Abstract: State information is communicated in a network to more efficiently utilize network resources. A first node forms a single extended query requesting state information from at least one logical image of a second node. The extended query is a single query requesting state information for multiple logical images of the first node. The requested state information includes the status of logical paths previously established between the multiple logical images of the first node and the at least one logical image of the second node. Upon sending the extended query to the second node, a single extended response can be formed at the second node having the requested state information.
