SAS Sample Test Suite
Error Conditions – Frames Sent to Initiator (Test Group B) 19
ACK/NAK Timeout detected after sending frame (TestB.4)
Target device shall send a Response frame with Check Condition status, sense key = Aborted
Command, and additional sense code = ACK/NAK TIMEOUT. 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 a SAS
Initiator.
2. The Testing Station is instructed to open an SSP connection to the DUT and transmit
a SCSI READ_BUFFER command for N bytes (specify). Close the connection
3. Allow the DUT to open an SSP connection to the Testing Station and transmit DATA
frame. The Testing Station is instructed not to send ACK/NAK to the DUT DATA
frame.
4. Wait for the DUT to timeout (1 ms) and send a DONE (ACK/NAK TIMEOUT).
Observable Results: Verify that the DUT transmit a SCSI response Abort with sense key of ABORTED
COMMAND and sense code of ACK/NAK TIMEOUT.
