Test 9.2.2 - SSP Command IU – TARGET PORT TRANSFER TAG

Purpose: To determine that the DUT properly sets the TARGET PORT TRANSFER TAG field.

References:

9.2.1 SAS Standard

Resource Requirements: SAS Protocol Analyzer and Generator. SAS Target with 2 LUNs within the same SSP
Target Port. If the DUT is an initiator, it will need to have software capable of generating SCSI traffic.

Revision History: September 23, 2004

Test Setup: The DUT and the Testing Station are physically connected. The SAS Initiator DUT is attached to the
SAS Target through a SAS Protocol analyzer.

Test Procedure (SSP Initiators):

• 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 a target.

• Allow the DUT to open a connection to the Testing Station and transmit a WRITE command. The

Testing Station should transmit XFER_RDY in response, with a Target Port Transfer Tag of 5555h.

Observable Results: If the DUT is an initiator, verify that the TARGET PORT TRANSFER TAG field is the same
in all DATA frames as the TARGET PORT TRANSFER TAG offered by the Testing Station in the XFER_RDY
frame.
