Test 7.5.6.2 - AIP –OPEN received Higher Priority
Purpose: To determine that the DUT, a SAS Expander properly handles a received OPEN of higher priority after
having transmitted AIP on a different physical link.
References:

Resource Requirements: SAS Protocol Analyzer and Generator. SAS Target.
Revision History: September 16, 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 an 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, and transmit a SCSI INQUIRY command. The Testing Station should close the
connection.
• The Testing Station should wait for an OpenAddress frame from the attached target. At this point the
DUT must be transmitting AIP to the attached target. The Testing Station should transmit an
OpenAddress to the attached target with a high priority, by setting AWT to 8000h.
Observable Results: Verify that the DUT transmits AIP to the attached target upon receiving the OpenAddress
from the attached target. Verify that the DUT forwards the OpenAddress from the Testing Station to the attached
target after having transmitted AIP to the attached target.
