SAS Sample Test Suite
Error Conditions – Frames Sent to Initiator (Test Group B) 23
ACK/NAK Timeout detected after sending frame (TestB.6)
Target device shall resend the frame once in a new connection with the Retransmit bit = 1 and all
other fields the same as in the first transmission of the frame. (I.e., can’t disable retries for a
response frame). This Response frame shall be sent in a new connection.
Test Procedure:
1. The Testing Station is instructed to start and complete a phy Reset sequence
followed by an Identify sequence with the DUT. Since the DUT is a target, the Testing
Station is instructed to transmit an Identify Address frame indicating that it is an
initiator.
2. The Testing Station is instructed to open an SSP connection to the Testing Station.
3. Wait for the DUT to transmit OPEN_ACCEPT and RRDY. The Testing Station is
instructed to transmit a SCSI INQUIRY command to the DUT then close the
connection.
4. Wait for the DUT to open an SSP Connection to the Testing Station. Allow the DUT to
transmit a SCSI Response. The Testing Station is instructed to transmit a NAK.
5. Wait for the DUT to Timeout 1 ms and send a DONE (ACK/NAK TIMEOUT).
Observable Results: Verify that the DUT retransmit Response Frame with Retransmit bit = 1.
