Test 7.5.8.1 - OPEN_REJECT – Pathway Blocked

Purpose: To determine that the DUT, a SAS Expander, properly increments the pathway blocked count.

References:

7.12.4.4 SAS Standard

Resource Requirements: SAS Protocol Analyzer and Generator. SAS Target.

Revision History: September 20, 2004

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, transmit a SCSI INQUIRY command, then close the connection.

• The target attached to the DUT is expected to transmit a connection request to the Testing Station

though the DUT. 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, then
close the connection. Response. The SMP OPEN from the Testing Station should have a higher AWT
than the OPEN from the attached target. Repeat this step 5 times.

Observable Results: Verify that the DUT transmits OPEN_REJECT (PATHWAY BLOCKED) to the attached
target OPEN request. Verify that the DUT increments the PATHWAY BLOCKED count each time an OPEN
request from the target is rejected.
