Autochanger Error Codes Hardware Error Codes Autochanger Error Codes NOTE Table B-7 Hardware Error Codes Hardware Errors are reported through the Request Sense Command (03H), (Byte 19, Table 5-6 on page 5-14), the Log Sense Command (4DH), and the Receive Diagnostic Results Command (1CH), (Byte 1, Table 3-30 on page 3-34). If an error is unrecoverable (i.e., something is broken or jammed beyond recovery without manual intervention), the Autochanger will take an additional step of attempting to identify the FRU that is causing the failure. A routine that performs a process of elimination for various FRUs runs automatically. It attempts to isolate the error to three or less FRUs. If no error can be found (or if error recovery was made), the unit will return a No Error status. If an error is found, a Hardware Error Code is returned when the command completes. Up to three FRUs will be returned to aide service in replacement priority. The FRU numbers returned are indicators for the most likely cause of an error, but may not be the actual cause of a problem. Simply changing the FRU listed may or may not fix the associated problem. Hardware Error Codes (medium and large models only) Error Code (hex.)
