Test 10.2.10 - STP OPERATIONS – READ DMA
Purpose: To determine that the DUT, an STP Bridge port, properly handles a READ DMA request.
References:
ATA/ATAPI 5/6
Resource Requirements: SAS Protocol Analyzer and Generator.
Revision History: April 14, 2005
Test Setup: The DUT and the Testing Station are physically connected. The DUT is also connected to a SATA disk
drive.
Test Procedure (STP Target):
• The Testing Station should start and complete a Phy Reset sequence followed by an Identify sequence
with the DUT. Since the DUT is an expander with an attached target the Testing Station should
transmit an Identify Address frame indicating that it is an initiator.
• The Testing Station should open an SMP Connection to the DUT an transmit a REPORT_GENERAL
SMP Request. The DUT should transmit a REPORT_GENERAL SMP Response.
• The Testing Station should open an SMP Connection to the DUT and transmit a REPORT STA PHY
SMP Request to the DUT Phy which is attached to the SAS Target. The DUT should transmit a
REPORT SATA PHY SMP Response with this information.
• The Testing Station should transmit an OpenAddress frame for an STP Connection to the STP Target
on the DUT. The Testing Station should wait for OPEN_ACCEPT.
• The Testing Station should transmit a SATA FIS of type Register Host to Device with Command Code
READ DMA.
Observable Results: Verify that the DUT transmits RESPONSE frame indicating that the command completed.
