drive will begin the first self-test segment. While the drive is performing a self-test in the background mode, it will terminate with a CHECK CONDITION status any SEND DIAGNOSTIC command it receives that meets either of the following criteria: a) The SlfTst bit is one b) The Function Code field contains a value other than 000b or 100b. When terminating the SEND DIAGNOSTIC command, the sense key shall be set to NOT READY and the additional sense code shall be set to LOGICAL UNIT NOT READY, SELF-TEST IN PROGRESS. While performing a self-test in the background mode, the drive will suspend the self-test to service any other command than SEND DIAGNOSTIC (with Function Code field set to 100b) WRITE BUFFER (with the mode set to any download microcode option), FORMAT UNIT and START STOP UNIT command. Suspension of the self-test to service the command will occur within two seconds. If SEND DIAGNOSTIC (with Function Code field set to 100b), WRITE BUFFER (with the mode set to any download microcode option), FORMAT UNIT or START STOP UNIT command is received, the drive will abort the self-test, update the self-test log, and service the command within two seconds after the command descriptor block has been validated. An initiator may terminate a self-test that is being performed in the background mode by issuing a SEND DIAGNOSTIC command with the Function Code field set to 100b (Abort background self-test function). Elements common to foreground and background self-test modes The Progress Indication field returned in response to a REQUEST SENSE command may be used by the application client at any time during execution of a self-test to poll the progress. While executing a selftest unless an error has occurred, the drive will respond to a REQUEST SENSE command by returning a sense key of NOT READY and an additional sense code of LOGICAL UNIT NOT READY - SELF-TEST IN PROGRESS with the sense key specific bytes set for progress indication. The initiator may obtain information about the twenty most recently completed self-tests by reading the self-test results log page. This is the only method bu which an initiator may obtain information about self-tests performed in the background mode. The default self-test results are not logged in the log page. Tests performed in self-test The spindle motor must be running at the correct speed for a SEND DIAGNOSTIC command to be executed.
