Test 9.5.1 - SSP RESPONSE IU – NO DATA PRESENT
Purpose: To determine that the DUT, an SSP Target port, properly sets the DATAPRES field to NO_DATA if a
command completes without sense data to return.

9.2.2.5.1 SAS Standard
Resource Requirements: SAS Protocol Analyzer and Generator.
Revision History: September 27, 2004
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.
