Expander I/O module discovery and management system

An Information Handling System (IHS), comprising:

• a processing system;
• and
• a memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide a device discovery and management engine that is configured to:
• receive, via a first secondary device that is housed in a secondary system chassis provided for a secondary system from a second secondary device that is housed in the secondary system chassis provided for the secondary system and coupled to the first secondary device, a first secondary device reporting communication that identifies:
• the secondary system chassis;
• and
• a first secondary device port on the first secondary device that is utilized by the second secondary device;
• determine, in response to receiving the first secondary device reporting communication, that the secondary system chassis identified in the first secondary device reporting communication is different than a primary system chassis that houses the processing system and, in response, assign a virtual slot to the first secondary device;
• and
• assign a virtual port that is associated with the virtual slot to the first secondary device port identified in the first secondary device reporting communication.

A method for discovering and managing devices, comprising:

• receiving, by a primary device that is housed in a primary system chassis provided for a primary system via a first secondary device that is housed in a secondary system chassis provided for a secondary system from a second secondary device that is housed in the secondary system chassis provided for the secondary system and coupled to the first secondary device, a first secondary device reporting communication that identifies:
• the secondary system chassis;
• and
• a first secondary device port on the first secondary device that is utilized by the second secondary device;
• determining, by the primary device in response to receiving the first secondary device reporting communication, that the secondary system chassis identified in the first secondary device reporting communication is different than the primary system chassis and, in response, assign a virtual slot to the first secondary device;
• and
• assigning, by the primary device, a virtual port that is associated with the virtual slot to the first secondary device port identified in the first secondary device reporting communication.
