Abstract:
In a bus extender apparatus operatively coupling a main SCSI bus to an auxiliary SCSI bus, the main bus having at least one initiator device operatively coupled thereto, each of the at least one initiator device accessible by an address on the main bus, the auxiliary bus having at least one target device operatively coupled thereto, the target device supporting tagged queuing, and the target device accessible by an address on the auxiliary bus, a method comprising the steps of:A. reserving an address on the auxiliary bus for each initiator device of the at least one initiator device having access to the auxiliary bus;B. detecting at the bus extender apparatus a main bus SELECTION signal asserted by an initiator device on the main bus, the main bus SELECTION signal including an initiator address field containing the address of the initiator device which asserts the main bus SELECTION signal;C. modifying the SELECTION signal to form a modified SELECTION signal including a modified initiator address field containing the address of the initiator device which asserts the main bus SELECTION signal reserved during said step of receiving; andD. asserting the modified SELECTION signal on the auxiliary bus.
