Method and apparatus for varying target behavior in a SCSI environment

摘要

A communications layer is provided between a host-based SCSI initiator and a SCSI target device to fully automate the validation process. The communications layer allows the host to direct variation and modification of the target parameters and behavior using vendor unique commands. The behavioral modification aims to establish interoperability by conforming the behavior of the target to the host behavior. The host-based initiator transports a suitable command structure to the target device containing appropriate ones of the vendor unique commands and associated parameter data. The target executes and otherwise processes the command structure to effectuate a reconfiguration according to the specifics of the command code. The command code is sufficient to fully reconfigure the SCSI target. Accordingly, the reconfiguration process is carried out in a fully automated fashion.
