Appendix B B-19

Autochanger Error Codes

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.

NOTE 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.
