Abstract
A SCSI bus extender apparatus coupling a main SCSI bus to a auxiliary SCSI bus includes a mechanism for detecting and processing SELECTION and RESELECTION signals transmitted between the two buses to accommodate target devices on the auxiliary bus which support tagged queuing in accordance with the SCSI protocol. The invention contemplates reserving an address on the auxiliary bus for each initiator on the main bus and performing the appropriate address conversions to enable target devices to properly identify the correct initiator device during a RESELECTION phase.
