SAS Sample Test Suite
Behavior After Receiving a Task Management Request (Test Group F) 98
QUERY ASYNCHRONOUS EVENT (TestF.9)
When QUERY ASYNCHRONOUS EVENT is received, the Target device shall determine whether there
is a Unit Attention condition pending for this I_T nexus.
If a Unit Attention is pending, then the Target device shall complete the task management request
by sending a Response frame with DATAPRES field set to RESPONSE_DATA and the RESPONSE
CODE field set to 08h, TASK MANAGEMENT FUNCTION SUCCEEDED. It shall include Additional
Response Information as defined in SAM4r14, 7.10.
If there is not a Unit Attention pending, then the Target device shall complete the task
management request by sending a Response frame with DATAPRES field set to RESPONSE_DATA
and the RESPONSE CODE field set to 00h, TASK MANAGEMENT FUNCTION COMPLETE. It shall
include Additional Response Information as defined in SAM4r14, 7.10.
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 Test Unit Ready command to the DUT. This should not be the first command
received by the DUT since power on. Close the connection
3. Allow the DUT to open an SSP connection to the Testing Station and transmit a SCSI
response frame to the received command.
4. The Testing Station is instructed to open an SSP connection to the DUT and transmit a
TASK MANAGEMENT frame QUERY_ASYNCHRONOUS_EVENT. When ACK is completed,
close the connection.
5. The Testing Station will allow the DUT to open an SSP connection.
Observable Results: Verify that the DUT transmit either a Response frame with DATAPRES field set
to RESPONSE_DATA and the RESPONSE CODE field set to 00h, TASK MANAGEMENT FUNCTION
COMPLETE. Or, DATAPRES field set to RESPONSE_DATA and the RESPONSE CODE field set to 08h,
TASK MANAGEMENT FUNCTION SUCCEDED.
6. Repeat 1-5 using an invalid LUN (0xFFFFFFFF FFFFFFFF) address
Observable Results: Verify that the DUT transmits a response frame with
DATAPRES field set to RESPONSE_DATA and the RESPONSE CODE field set to
INVALID LUN
