References:
7.16.4 SAS Standard
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 (Targets):
• 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 initiator.
• The Testing Station should open an SSP connection to the DUT.
• Wait for the DUT to transmit OPEN_ACCEPT and RRDY.
Observable Results: Verify that the DUT transmitted RRDY when an SSP connection was opened.
