Abstract
A system for managing input/output drawers within a data processing system. A unique identifier is assigned to each of a plurality of drawers, and is used by the operating system to identify the drawers in the system regardless of how these drawers are interconnected. Another unique PCI-bridge identifier is assigned to each of a plurality of PCI Host bridges (PHBs) from all drawers, and is used by the operating system to perform input/output processes to devices associated with the plurality of PHBs such that the ODM object for each of the PHBs remains the same regardless of how the drawer is interconnected in the system. When a new drawer is added to the system, a new unique identifier is assigned to the new drawer ensuring that the unique identifiers previously assigned to the other drawers are not used to identify the new drawer.
