  "note": "The status is 02h, distinct from the sense key. It does not by itself identify a defective drive: an unsupported request, changed device state or access restriction can also cause a report. [seagate-sense] iSCSI carries sense data with this status using Autosense; do not assume that every transport requires a separate REQUEST SENSE command. [rfc7143]",
