## Constants

- NVME\_CTRL\_ANACAP\_OPT

  If set, then the controller is able to report ANA Optimized state.

- NVME\_CTRL\_ANACAP\_NON\_OPT

  If set, then the controller is able to report ANA Non-Optimized state.

- NVME\_CTRL\_ANACAP\_INACCESSIBLE

  If set, then the controller is able to report ANA Inaccessible state.

- NVME\_CTRL\_ANACAP\_PERSISTENT\_LOSS

  If set, then the controller is able to report ANA Persistent Loss state.

- NVME\_CTRL\_ANACAP\_CHANGE

  If set, then the controller is able to report ANA Change state.

- NVME\_CTRL\_ANACAP\_GRPID\_NO\_CHG

  If set, then the ANAGRPID field in the Identify Namespace data structure (*struct nvme\_id\_ns*.anagrpid), does not change while the namespace is attached to any controller.

- NVME\_CTRL\_ANACAP\_GRPID\_MGMT

  If set, then the controller supports a non-zero value in the ANAGRPID field of the Namespace Management command.
