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 (Initiators):
• The Testing Station should start and complete a Phy Reset sequence followed by an Identify sequence
with the DUT. Since the DUT is an initiator the Testing Station should transmit an Identify Address
frame indicating that it is a target.
• Wait for the DUT to open an SSP connection to the Testing Station. Allow the DUT to transmit a SCSI
Command to the Testing Station, then close the connection.
• The Testing Station should transmit an OpenAddress frames to the DUT with a correct destination
SAS Address.
• Wait for the DUT to transmit OPEN_ACCEPT and RRDY.
Observable Results: Verify that the DUT transmitted RRDY when an SSP connection was opened.
