Test 7.4.3 - Closing SSP Connections – DONE (CREDIT TIMEOUT)
Purpose: To determine that the DUT properly responds when RRDY has not been received for an impending
transaction.
References:
7.16.6 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 (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. The Testing Station should not
transmit RRDY to grant credit for the DUT to transmit a SCSI Command to the Testing Station.
Observable Results: Verify that the DUT transmitted DONE (CREDIT TIMEOUT) within 1 msec of opening the
SSP connection.
