STORAGE_PROTOCOL_NVME_DATA_TYPE enumeration (winioctl.h)

Describes the type of NVMe protocol-specific data that's to be queried during an IOCTL_STORAGE_QUERY_PROPERTY request.

Syntax

typedef enum _STORAGE_PROTOCOL_NVME_DATA_TYPE {
  NVMeDataTypeUnknown = 0,
  NVMeDataTypeIdentify,
  NVMeDataTypeLogPage,
  NVMeDataTypeFeature,
  NVMeDataTypeLogPageEx,
  NVMeDataTypeFeatureEx
} STORAGE_PROTOCOL_NVME_DATA_TYPE, *PSTORAGE_PROTOCOL_NVME_DATA_TYPE;

Constants

 
NVMeDataTypeUnknown
Value: 0
Unknown data type.
NVMeDataTypeIdentify
Identify data type. This can be either Identify Controller data or Identify Namespace data. When this type of data is being queried, the ProtocolDataRequestValue field of STORAGE_PROTOCOL_SPECIFIC_DATA will have a value of NVME_IDENTIFY_CNS_CONTROLLER for adapter or NVME_IDENTIFY_CNS_SPECIFIC_NAMESPACE for namespace. If the ProtocolDataRequestValue is NVME_IDENTIFY_CNS_SPECIFIC_NAMESPACE, the ProtocolDataRequestSubValue field from the STORAGE_PROTOCOL_SPECIFIC_DATA structure will have a value of the namespace ID.
NVMeDataTypeLogPage
Log page data type.
NVMeDataTypeFeature
Feature data type.

Remarks

When using IOCTL_STORAGE_QUERY_PROPERTY to retrieve protocol-specific information in the STORAGE_PROTOCOL_DATA_DESCRIPTOR, configure the STORAGE_PROPERTY_QUERY structure as follows:

To specify a type of NVMe protocol-specific information, configure the STORAGE_PROTOCOL_SPECIFIC_DATA structure as follows:

  • Set the ProtocolType field to ProtocolTypeNVMe.
  • Set the DataType field to an enumeration value defined by STORAGE_PROTOCOL_NVME_DATA_TYPE:
    • Use NVMeDataTypeIdentify to get Identify Controller data or Identify Namespace data.
    • Use NVMeDataTypeLogPage to get log pages (including SMART/health data).
    • Use NVMeDataTypeFeature to get features of the NVMe drive.
