SYNOPSIS¶

enum nvme_smart_crit {
NVME_SMART_CRIT_SPARE ,
NVME_SMART_CRIT_TEMPERATURE ,

NVME_SMART_CRIT_PMR_RO

};

Constants¶

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.
