Parameter List Length must be 0 when the SlfTst bit is one. Otherwise, CHECK CONDITION status
will be generated with a sense key of ILLEGAL REQUEST and additional sense of INVALID FIELD IN
CDB. If the SlfTst bit is zero, it should be set to the length of the page to be transferred in the DATA
OUT phase of the command. If it does not match the expected length of the page a CHECK
CONDITION status will be also generated with a sense key of ILLEGAL REQUEST and additional
sense of INVALID FIELD IN CDB.
If the motor is not running at the correct speed when the command is received, it is rejected by a CHECK
CONDITION status with a NOT READY sense key.
If a fault is detected during the default or foreground self-test, a CHECK CONDITION is reported as an
end status. If a fault is detected during the background self-test, it is logged in the log page for later
retrieval by a LOG SENSE command.
See Section 11.17, "Diagnostics" on page 212 for detailed listing of operations carried out by SEND
DIAGNOSTIC command and Power on Diagnostics.
