BREAK TIMEOUT after sending BREAK redundant primitive (TestD.8)
If the Target device sends a BREAK redundant primitive, it should receive a BREAK or BREAK_REPLY
redundant primitive in response within 1 ms. If the Target device does not receive this response
within 1 ms, it shall consider the connection broken.
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 DUT.
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 to the Testing Station.
5.
When the DUT transmits CLOSE (NORMAL) to close the connection, the Testing
Station is instructed to not transmit CLOSE (NORMAL) in response.
6.
Wait for the DUT to transmit BREAK primitive sequence (6 times). The Testing
Station is instructed to not respond to the sequence.
Observable Results: Verify that the DUT after 1 ms timeout period does nothing and assumes the
connection is closed.
