Abstract
A bus reset control module associated with a fibre-SCSI bridge manages target resets sent from a fibre bus to one or more SCSI buses to reduce or eliminate unnecessary bus resets of SCSI buses having sequential devices, such as tape storage drives. The bus reset control module accepts target resets from a fibre bus host to intercept the initiation of bus resets and communicates with target devices of the SCSI bus to determine whether the target devices are faulty. The bus reset control module issues bus resets to SCSI buses having a faulty target device but prevents issuance of bus resets to SCSI buses that do not have a faulty target device so that a sequential device interfaced with a SCSI bus is not subject to a bus reset if all devices associated with the SCSI bus are operating properly.
