Sorry to be picky, but:
Is there a chance the _no_ sense data will be provided? If so we'd end up starting the error handler, calling REQUEST SENSE (which will fail, too), and finally offlining the device. I'd rather provide a default sense code for these cases. Plus please use SAM_STAT_CHECK_CONDITION instead of CHECK_CONDITION << 1.
