Error Conditions – Frames Received from Initiator (Test Group C) 25
Error Conditions – Frames Received from Initiator (Test Group C)
Errors on COMMAND frames (TestC.1, TestC.2, TestC.3.1-TestC.3.3, TestC.4.1-TestC.1)
CRC or other error resulting in NAK to Initiator (TestC.1)
Target device shall send NAK to the Initiator. The frame is not recognized as a Command Frame.
The frame is discarded. If the Initiator resends the COMMAND frame, the Target device will see
that as a new command.
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 a SSP connection to the DUT and transmit a
SCSI_INQUIRY command with an invalid CRC.
3. Wait for the DUT to transmit NAK (CRC ERROR).
4. The Testing Station is instructed to open a SSP connection to the DUT and transmit a
SCSI_INQUIRY command with a valid CRC.
Observable Results: Verify that the DUT transmit ACK.
