The original translation created collisions on Inquiry VPD 83 for many existing devices. Newer specifications provide other ways to translate based on the device's version can be used to create unique identifiers. Version 1.1 provides an EUI64 field that uniquely identifies each namespace, and 1.2 added the longer NGUID field for the same reason. Both follow the IEEE EUI format and readily translate to the SCSI device identification EUI designator type 2h. For devices implementing either, the translation will use this type, defaulting to the EUI64 8-byte type if implemented then NGUID's 16 byte version if not. If neither are provided, the 1.0 translation is used, and is updated to use the SCSI String format to guarantee a unique identifier. Knowing when to use the new fields depends on the nvme controller's revision. The NVME_VS macro was not decoding this correctly, so that is fixed in this patch and moved to a more appropriate place. Since the Identify Namespace structure required an update for the NGUID field, this patch adds the remaining new 1.2 fields to the structure. Signed-off-by: Keith Busch <keith.busch@intel.com> |
