1.7.7Fatal hardware errors

(1)Self-diagnostic errors

If a hardware fatal error is detected during the initial self-diagnosis, in off-line self diagnosis or in on-line self-diagnosis (SEND DIAGNOSTIC command), rotation of the spindle motor will be halted.

When in this state, the IDD reports the CHECK CONDITION status for all input/output operation requests except the REQUEST SENSE command. The sense data reported at this time indicate HARDWARE ERROR [=4] / Diagnostic failure on component “nn” [=40-nn]. It is necessary for the INIT either to generate a RESET condition or send a TARGET RESET message and attempt to recover from the error state. For recommended procedures for error recovery methods, see the explanation in Section 5.2 “INIT’s Error Recovery Methods (Recommended).” Furthermore, see Section 6.1.1 “Self-diagnostic Function” in “Product Manual.”

(2)Unrecoverable hardware errors

Limited to cases in which a fatal hardware error occurs during execution of a command, and termination processing such as a CHECK CONDITION status report cannot be executed, the IDD may halt rotation of the spindle motor.

After this state occurs, the IDD reports the CHECK CONDITION status for all input/output operation requests except the REQUEST SENSE command. The sense data reported at this time indicate HARDWARE ERROR [=4] / Internal target failure [=44-nn]. If this state is reported continuously for input/output operation requests, it is necessary for the INIT to generate a RESET condition or send a TARGET RESET message and attempt to recover from the error state. For recommended procedures for error recovery methods by the INIT, see the explanation in Section 5.2 “INIT’s Error Recovery Methods (Recommended).”
