Parameter Description


critical warning

Critical warning, such as overtemperature and insufficient redundant space.

Example: no warning

There are the following types of critical warning:

  • The available space is smaller than the threshold.
  • The temperature exceeds the threshold.
  • An internal error downgrades the NVM subsystem reliability.
  • The medium is read-only.
  • Device backup failed.
