SAS Sample Test Suite
Behavior After Receiving a Task Management Request (Test Group F) 104
SCSI CDB – Identical Read command sequence with TAG Conflict (no retran bit)(TestF.15.3)
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 a SAS Initiator.
2. The Testing Station is instructed to open an SSP connection to the DUT and transmit a SCSI
READ command for 512 bytes w/TAG = 0018. Close the connection..
3. Before DUT responds, the Testing Station is instructed to open an SSP connection to the
DUT and transmit an identical SCSI READ command as first Write w/TAG = 0018. Close the
connection.
Observable Results: Verify that the DUT responds to the duplicate write with a response of Status
CHECK CONDITION, Sense Key of ABORT COMMAND and ASC/Q of OVERLAPPING COMMANDS
ATTEMPTED.
4. The Testing Station is instructed to open a connection to the DUT and transmit a Test Unit
Ready command frame w/TAG = 001A.
Observable Results: Verify that the DUT responds to the TUR data sequence with a Status=Good
w/TAG = 001A
