Test 9.5.4 - SSP RESPONSE IU – SENSE/RESPONSE DATA NOT PRESENT
Purpose: To determine that the DUT, an SSP Target port, properly sets the SENSE DATA LENGTH, SENSE
DATA, RESPONSE DATA LENGTH, and RESPONSE DATA fields if a command completes without sense data
to return.

Resource Requirements: SAS Protocol Analyzer and Generator.

Test Setup: The DUT and the Testing Station are physically connected.
Test Procedure (SSP Target):
• The Testing Station should start and complete a Phy Reset sequence followed by an Identify sequence
with the DUT. Since the DUT is a target the Testing Station should transmit an Identify Address frame
indicating that it is a SAS Initiator.
• The Testing Station should open an SSP connection to the DUT and transmit a SCSI Test Unit Ready
command to the DUT. This should not be the first command received by the DUT since power on.
Close the connection
• Allow the DUT to open an SSP connection to the Testing Station and transmit a SCSI response frame
to the received command.
Observable Results: Verify that if the DUT sets the DATAPRES field to NO_DATA if the command completes
without sense data to return when the command finishes with status GOOD. The SENSE DATA LENGTH and
RESPONSE DATA LENGTH fields shall be set to 0. The SENSE DATA and RESPONSE DATA fields should not
be present.
