C141-E035-0 3EN 6 - 3 The IDD does not reply to the SCSI bus for up to 2 seconds after the initial self-diagnostics is started. After that, the IDD can accept the I/O operation request correctly , but the received command, except the executable commands under the not ready state (such as INQUIRY, START/STOP UNIT), is terminated with the CHECK CONDI[...]

C141-E035-02EN 6 - 4 When an error is detected in the self-diagnostics, the IDD terminates the SEND DIAGNOSTIC command with the CHECK CONDITION status . At this time only when an error is detected in the hardware function test, the LED on the front panel of the disk drive blinks. The INIT should issue the REQUEST SENSE command when the CHECK CONDIT[...]
