The drive starts its short self-test routine in background mode. The drive starts its extended self-test routine in background mode. Reserved Abort the current self-test in the background mode. This value is only valid if a previous SEND DIAGNOSTIC command specified a background self-test function and that function has not been completed. The drive starts its short self-test routine in the foreground mode. The device server starts its extended self-test routine in the foreground mode. Reserved Figure 158. SEND DIAGNOSTIC (1D) ! DevOfl is ignored by the drive for compatibility. ! UntOfl is ignored by the drive for compatibility. ! 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.
