Test 9.6.2 - SSP ERROR HANDLING – Invalid LUN

Purpose: To determine that the DUT, an SSP Target port, properly handles a TASK frame received with an invalid
LUN.

References:

9.2.2.2 SAS Standard

Resource Requirements: SAS Protocol Analyzer and Generator.

Revision History: March 3, 2005

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 TASK frame of

function LOGICAL UNIT RESET with an invalid LUN. Close the connection

• Allow the DUT to open an SSP connection and transmit a SCSI response frame to the received TASK

frame.

Observable Results: Verify that the DUT sets the DATAPRES field to RESPONSE_DATA and the RESPONSE
CODE field to INVALD LOGICAL UNIT.
