The target then either switches to the STATUS phase if the command is complete or if it is ready to transfer data the DATA phase The data transfer length is set by the Host in the Command Descriptor Block The target will remain in the DATA phase until all the data is transferred The target then initiates a STATUS phase and transfers one byte to the Host to indicate whether the target has successfully completed the command If the target has detected an error the next command that the Host is expected to send is REQUEST SENSE This allows the target to return further status information to the Host The target completes the SCSI sequence by going to the MESSAGE IN phase and transferring a COMMAND COMPLETE message to the Host The target then releases BSY allowing the bus to go to the BUS FREE State 5 2 2 Disconnect In order to improve bus usage and performance the unit is capable of temporarily disconnecting from the bus consequently allowing other initiator target communications to take place To do so however the Host needs to support Disconnect Re select The mechanism for performing the Disconnect Re select procedure is implemented as follows 1 3 The Host arbitrates for the SCSI bus and upon winning the bus it proceeds to select target device Prior to releasing SEL and completing the selection phase the Host asserts the ATN line The Host then releases SEL and BSY to allow the target to assume control of the SCSI bus
