ABSTRACT:
A method and system for selectively interconnecting two SCSI host buses where each SCSI host bus includes a host device and multiple addressable SCSI target devices, each SCSI target device having a multibit SCSI ID associated therewith. A SCSI cross-link repeater is interposed between the two SCSI host buses and selectively enabled. Each time the SCSI cross-link repeater is enabled, the repeater enable signal is utilized to automatically alter the most significant bit of the multibit SCSI ID associated with each SCSI target device on the second SCSI host bus, such that those SCSI target devices do not duplicate the SCSI IDs of the SCSI target devices on the first SCSI host bus. Disabling the SCSI cross-link repeater automatically resets the most significant bit of the multibit SCSI IDs, restoring the original SCSI IDs for those devices.
