Test 7.5.5.5 - BREAK – Connection Request not Transmitted
Purpose: To determine that the DUT, a SAS Expander responds to received BREAK properly.
References:
7.12.2.1, 7.12.6 SAS Standard
Resource Requirements: SAS Protocol Analyzer and Generator. SAS Target.
Revision History: February 15, 2005
Test Setup: The DUT and the Testing Station are physically connected. The DUT is physically connected to a SAS
Target.
Test Procedure (SAS Expander):
• The Testing Station should start and complete a Phy Reset sequence followed by an Identify sequence
with the DUT. Since the DUT is an expander with an attached target the Testing Station should
transmit an Identify Address frame indicating that it is an initiator.
• The Testing Station should open an SMP Connection to the DUT and transmit a REPORT_GENERAL
SMP Request. The DUT should transmit a REPORT_GENERAL SMP Response.
• The Testing Station should open an SMP Connection to the DUT and transmit a DISCOVER SMP
Request to the DUT Phy which is attached to the SAS Target. The DUT should transmit a DISCOVER
SMP Response with this information.
• The Testing Station should transmit an OpenAddress frame for an SSP Connection to the SAS Target
attached to the DUT, followed by a BREAK, within 10 dwords.
Observable Results: Verify that the DUT does not transmit BREAK to the SAS Target unless it has already
transmitted the SSP OpenAddress frame to the target. Verify that after transmitting BREAK back to the Testing
Station, the DUT does not forward any dwords from the attached SAS Target to the Testing Station, such as an
OPEN_ACCEPT frame.
