- NVME_SMART_CRIT_SPARE
- If set, then the available spare capacity has fallen below the
threshold.
- NVME_SMART_CRIT_TEMPERATURE
- If set, then a temperature is either greater than or equal to an over
temperature threshold; or less than or equal to an under temperature
threshold.
- NVME_SMART_CRIT_DEGRADED
- If set, then the NVM subsystem reliability has been degraded due to
significant media related errors or any internal error that degrades NVM
subsystem reliability.
- NVME_SMART_CRIT_MEDIA
- If set, then all of the media has been placed in read only mode. The
controller shall not set this bit if the read-only condition on the media
is a result of a change in the write protection state of a namespace.
- NVME_SMART_CRIT_VOLATILE_MEMORY
- If set, then the volatile memory backup device has failed. This field is
only valid if the controller has a volatile memory backup solution.
- NVME_SMART_CRIT_PMR_RO
- If set, then the Persistent Memory Region has become read-only or
unreliable.
