Authenticating a processing system accessing a resource via a resource alias address
First Claim
1. A method, comprising:
- maintaining an association of processing system identifiers with resources, including a first and second resources;
receiving a request from requesting processing system software in a host for use of the first resource that provides access to the second resource, and wherein the request includes a submitted processing system identifier, wherein the received request is associated with a path group identifier provided by the requesting processing system software;
determining whether the path group identifier associated with the request matches a path group identifier associated with the first and second resources;
determining whether the submitted processing system identifier is one of the processing system identifiers associated with the first and second resources; and
providing the requesting processing system software access to the first resource that the processing system uses to access the second resource in response to determining that the submitted processing system identifier is one of the processing system identifiers associated with the first and second resources and determining that the path group identifier associated with the request matches the path group identifier associated with the first and second resources, wherein the first resource provides access to the second resource or an element identified by the second resource.

Abstract
Provided are a method, system, and article of manufacture for authenticating a processing system accessing a resource. An association of processing system identifiers with resources, including a first and second resources, is maintained. A request from a requesting processing system in a host is received for use of a first resource that provides access to a second resource, wherein the request is generated by processing system software and wherein the request further includes a submitted processing system identifier included in the request by host hardware in the host. A determination is made as to whether the submitted processing system identifier is one of the processing system identifiers associated with the first and second resources. The requesting processing system is provided access to the first resource that the processing system uses to access the second resource.

6. A system in communication with processing systems in a host, wherein each processing system includes processing system software, comprising:
-
a computer readable storage medium including an association of processing system identifiers with resources, including a first and second resources; an Input/Output (“
I/O”
) manager to perform operations, the operations comprising;maintaining an association of processing system identifiers with resources, including a first and second resources; receiving a request from requesting processing system software in a host for use of the first resource that provides access to the second resource, and wherein the request includes a submitted processing system identifier, wherein the received request is associated with a path group identifier provided by the requesting processing system software; determining whether the path group identifier associated with the request matches a path group identifier associated with the first and second resources; determining whether the submitted processing system identifier is one of the processing system identifiers associated with the first and second resources; and providing the requesting processing system access to the first resource that the processing system uses to access the second resource in response to determining that the submitted processing system identifier is one of the processing system identifiers associated with the first and second resources and determining that the path group identifier associated with the request matches the path group identifier associated with the first and second resources, wherein the first resource provides access to the second resource or an element identified by the second resource. - View Dependent Claims (7, 8, 9, 10)

11. An article of manufacture comprising a computer readable storage medium implementing an Input/Output (I/O) manager in communication with processing systems in a host, wherein each processing system includes processing system software, wherein the I/O manager is executed to cause operations, the operations comprising:
-
maintaining an association of processing system identifiers with resources, including a first and second resources; receiving a request from requesting processing system software in a host for use of the first resource that provides access to the second resource, and wherein the request includes a submitted processing system identifier, wherein the received request is associated with a path group identifier provided by the requesting processing system software; determining whether the path group identifier associated with the request matches a path group identifier associated with the first and second resources; determining whether the submitted processing system identifier is one of the processing system identifiers associated with the first and second resources; and providing the requesting processing system software access to the first resource that the processing system uses to access the second resource in response to determining that the submitted processing system identifier is one of the processing system identifiers associated with the first and second resources and determining that the path group identifier associated with the request matches the path group identifier associated with the first and second resources, wherein the first resource provides access to the second resource or an element identified by the second resource. - View Dependent Claims (12, 13, 14, 15)
