Test 9.5.2 - SSP RESPONSE IU – SENSE 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.
References:
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. The DUT is not powered on.
Test Procedure (SSP Target):
• Power on the DUT.
• 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 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 the DUT sets the DATAPRES field to SENSE_DATA and the command
completes with sense data to return when the command finishes with status CHECK CONDITION.
