Test Setup: The DUT and the Testing Station are physically connected. This test is only applicable to targets.
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 a SSP connection to the DUT and transmit a SCSI_INQUIRY
command.
• Wait for the DUT to transmit ACK followed by SCSI Response.
• The Testing Station should not transmit ACK or NAK to the SCSI Response frame.
• The Testing Station should transmit a second SCSI_INQUIRY command with a different TAG than
the first SCSI INQUIRY command.
Observable Results: Verify that the DUT aborts the first INQUIRY command with DONE(ACK/NAK TIMEOUT)
after the ACK/NAK timeout of 1 msec.
