Test 7.5.1.1 - Connections through Expanders – OPEN SSP Target
Purpose: To determine that the DUT, an SSP Target, can properly open a connection through an expander to
transmit data or status.

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 (SSP Target):
• 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 Edge Expander.
• The Testing Station should open an SSP connection to the DUT from another address, imitating a SAS
Initiator.
• 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 to the same address that sourced
the SCSI INQUIRY command.
• Before transmitting OPEN_ACCEPT the Testing Station should transmit AIP(NORMAL) followed by
AIP(WAITING ON DEVICE)
• Allow the DUT to transmit a SCSI Data frame to the Testing Station.
• When the DUT transmits CLOSE (NORMAL) to close the connection, the Testing Station should
transmit CLOSE (NORMAL) in response.
• Wait for the DUT to open an SSP connection to the Testing Station to the same address that sourced
the SCSI INQUIRY command. Allow the DUT to transmit a SCSI Response frame to the Testing
Station.
• When the DUT transmits CLOSE (NORMAL) to close the connection, the Testing Station should
transmit CLOSE (NORMAL) in response.
Observable Results: Verify that the DUT successfully transmitted both SCSI Response and Data frames.
