Authenticating a processing system accessing a resource
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 a requesting processing system 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 request is generated by processing system software in the host and wherein a host identifier is included in the received request by host hardware in the host;
determining whether the submitted processing system identifier is 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 associated with the first and second resources, wherein the first resource provides the host identified by the host identifier 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.

1. A method, comprising:
-
maintaining an association of processing system identifiers with resources, including a first and second resources; receiving a request from a requesting processing system 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 request is generated by processing system software in the host and wherein a host identifier is included in the received request by host hardware in the host; determining whether the submitted processing system identifier is 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 associated with the first and second resources, wherein the first resource provides the host identified by the host identifier access to the second resource or an element identified by the second resource. - View Dependent Claims (2)

3. A method, comprising:
-
maintaining an association of processing system identifiers with base and alias addresses; receiving a request from a requesting processing system in a host for use of the alias address that provides access to the base address, wherein the request includes a submitted processing system identifier, and wherein the request is associated with a path group identifier identifying a path group, wherein base and alias addresses are associated with a path group identifier; determining whether the path group identifier associated with the request is associated with the base and alias addresses in the request; determining whether the submitted processing system identifier is associated with the path group identifier in response to determining that the path group identifier associated with the request is associated with the base and alias addresses in the request; and providing the requesting processing system access to the alias address that the processing system uses to access the base address in response to determining that the submitted processing system identifier is associated with the path group identifier associated with the base and alias address in the request. - View Dependent Claims (4, 13, 14)

5. 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 a requesting processing system 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 request is generated by processing system software in the host and wherein a host identifier is included in the received request by host hardware in the host; 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 associated with the first and second resources, wherein the first resource provides the host identified by the host identifier access to the second resource or an element identified by the second resource. - View Dependent Claims (6, 8, 16)

9. An article of manufacture comprising a non-transitory 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 a requesting processing system 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 request is generated by processing system software in the host and wherein a host identifier is included in the received request by host hardware in the host; 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 associated with the first and second resources, wherein the first resource provides the host identified by the host identifier access to the second resource or an element identified by the second resource. - View Dependent Claims (10)
