Appendix A
DEFINITION OF VENDOR UNIQUE SENSE DATA
INFORMATION
This appendix lists the internal status codes with their descriptions.
The internal status code is located at byte offset 18 of the REQUEST SENSE
data and may be available for certain types of failures.
NOTE
Byte 18 of the REQUEST SENSE data has two formats: a byte code
and a bit flags format. The bit flags format is used when there is no
internal status code to report and can be quickly distinguished by
checking to see if bit 7 of byte 18 is set to 1.
