Abstract
The present invention provides methods for automatically assigning addresses to expanders in a computer I/O subsystem that is coupled to one or more host computers. The computer I/O subsystem includes one or more peripheral buses, a set of peripheral devices, and a set of expanders with each expander being arranged to couple a pair of peripheral buses. The peripheral devices are coupled to the peripheral buses. In this configuration, a host computer selects a peripheral device as a target device and writes an address data pattern to the selected target device. The host computer then selects the target device and reads the address data pattern from the target device. Unique addresses are then assigned to one or more expanders coupling the host computer and the target device starting from the address data pattern, preferably by incrementing the address data pattern.
