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. The method is based on the Fiber Channel N_Port virtualization for a physical Fiber Channel N_Port. Multiple virtual Fiber 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 virtualization.

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. The method is based on the Fiber 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.

Method for managing virtual instances of a physical port attached to a network

A computer-implemented method, apparatus, and computer-usable program code to generate unique identifiers for a logically partitioned and/or virtualized data processing system. A number of computing entities supported by the data processing system are identified to form a number of identified entities. A set of unique identifiers is generated based upon the number of identified entities. A unique identifier from the set of unique identifiers is assigned to a logical computing entity during operation of the data processing system.
