Last Failure Codes
A Last Failure Code is a number that uniquely-describes an
unrecoverable condition. It is found at byte offset 104 to 107 and will
only appear in Figure D–2, “Template 01 - Last Failure Event Sense
Data Response Format” on page D–4, and Figure D–4, “Template 05 -
Failover Event Sense Data Response Format” on page D–7.
Last Failure Code Structure
Figure D–13 shows the structure of a Last Failure Code. If you
understand its structure, you will be able to translate it, bypassing the
FMU.

Note Do not confuse the Last Failure Code with the Instance Code (see
page D–16). They appear at different byte offsets and convey different
information.
