Test 7.4.2 - Closing SSP Connections – DONE (ACK/NAK TIMEOUT)
Purpose: To determine that the DUT properly responds when ACK or NAK has not been received for a transmitted
frame.
References:
7.16.6 SAS Standard
Resource Requirements: SAS Protocol Analyzer and Generator
Revision History: September 13, 2004
Test Setup: The DUT and the Testing Station are physically connected.
Test Procedure (Targets):
• 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 an initiator.
• The Testing Station should open an SSP connection to the Testing Station.
• Wait for the DUT to transmit OPEN_ACCEPT and RRDY. The Testing Station should transmit a
SCSI INQUIRY command to the DUT, then close the connection.
• Wait for the DUT to open an SSP Connection to the Testing Station. Allow the DUT to transmit a
SCSI Response. The Testing Station should not transmit ACK or NAK.
Observable Results: Verify that the DUT transmitted DONE (ACK/NAK TIMEOUT) within 1 msec of
transmitting the Command or Response frame.
