Task Management Flag and Information Units

All SCSI initiators send Task Management functions using T1.
All SCSI targets return FCP_RSP to Task Management functions using I4.
The RSP_CODE in the FCP_RSP_INFO field indicates the result of the Task
Management function. The SCSI Status byte and FCP_SNS_INFO are ignored for I4
information units sent in response to a Task Management function.
