Subnet management in virtual host channel adapter topologies
First Claim
1. A computer program product for subnet management in virtual host channel adapter topologies, the computer program product including a non-transitory computer readable storage medium including computer executable instructions that, when executed by a processor, direct the processor to perform a method, the method comprising:
- receiving a request to add a new logical host channel adapter (HCA) to a subnet from the new logical HCA;
updating a logical switch port topology control block of the subnet to reflect a pointer to the new logical HCA; and
updating a port topology control block of the new logical HCA to reflect a pointer to the logical switch port topology control block.

Abstract
A computer program product for subnet management in virtual host channel adapter topologies includes a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method. The method includes receiving a request to add a new logical host channel adapter (HCA) to the subnet, updating a logical switch port topology control block to reflect a pointer to the new logical HCA, and updating a port topology control block of the logical HCA to reflect a pointer to the logical switch port.

9. An apparatus for subnet management in virtual host channel adapter topologies, the apparatus comprising:
-
at least one processor; a logical switch representation of at least one physical port, wherein the logical switch representation is managed through a subnet management agent; a logical host channel adapter (HCA) representation of at least one host channel adapter, wherein the logical HCA representation is managed by the subnet management agent; and a logical connection between the logical switch representation and the logical HCA representation configured to enable communications between the host channel adapter and the physical port, wherein the communications are managed through a subnet management interface in communication with the subnet management agent.
