## Discussion

Discussion If the task is unable to be delivered to the device due to a failure in the SCSI Protocol Layer, such as a bus reset or communications error, but the device is is known to be functioning properly, the task status shall be set to kSCSITaskStatus_DeliveryFailure. This can also be reported if the task could not be delivered due to a protocol error that has since been corrected.
