Test 7.4.6 - Closing SSP Connections – BREAK Sourced by DUT
Purpose: To determine that the DUT properly sources BREAK when required.
References:
7.12.7 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 DUT.
• 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 to the Testing Station.
• When the DUT transmits CLOSE (NORMAL) to close the connection, the Testing Station should not
transmit CLOSE (NORMAL) in response.
Observable Results: Verify that the DUT transmitted BREAK within 1 msec of transmitting CLOSE (NORMAL)
to the Testing Station.
