Patent ID: 7707465

Claim:
A computer-implemented method in a data processing environment that includes a plurality of host computer systems that are coupled to a plurality of I/O adapters utilizing a switched fabric for routing an error message to only ones of said plurality of host computer systems that are affected by an error identified by said error message, said computer-implemented method comprising: detecting, by one of said plurality of I/O adapters, an error in said one of said plurality of adapters; generating, by said one of said plurality of I/O adapters, an error message that includes specific information about said error and includes an identifier that identifies said one of said plurality of I/O adapters; utilizing routing tables that are stored only in hardware switches in said fabric that are connected directly to at least one of said plurality of host computer systems to identify ones of said plurality of host computer systems that are affected by said error; and routing, by said hardware switches that are connected to said at least one of said plurality of host computer systems, said error message to only said identified ones of said host computer systems.
