15 Error Reporting
This section lists the error codes and corresponding meanings that can be returned by
the library.
Note:
For error codes returned by tape drives (medium errors), refer to
the tape drive manual for that specific drive type. These manuals
can be found on the drive manufacturer's Web site.
Errors are reported when a device returns a CHECK CONDITION status after trying to execute
a command received from an initiator. The initiator can issue a REQUEST SENSE command to
learn more about the error. The sense data returned by the library includes a Sense
Key, an Additional Sense Code (ASC), and an Additional Sense Code Qualifier (ASCQ).
These three pieces of information combine to indicate a specific error condition.

Sense Keys

The following table describes the sense key valuations returned by the library. The
sense key indicates the nature of the error condition in a very general way.
