The sense key, additional sense code and additional sense code qualifier provide a hierachy of information. The intention of the hierarchy is to provide a top down approach for an initiator to determine information relating to the error and exception conditions. The sense key provides generic categories in which error and exception condition can be reported. Initiators would typically
use sense keys for high level error recovery procedures. Additional INTERFACE sense codes provide further detail describing the sense key.
Additional sense code qualifiers add further detail to the additional sense code. The additional sense code and additional sense code qualifier can be used by initiators where sophisticated error recovery procedures require detailed information describing the error and exception conditions.
The sense key field is mandatory and indicates generic information describing an error or exception condition. The sense key used are defined in Table 3.29.
