Describes the type of NVMe protocol-specific data that is to be queried during an IOCTL_STORAGE_QUERY_PROPERTY request.
NVMeDataTypeUnknownUnknown data type.
NVMeDataTypeIdentifyGet Identify data, which can be either Identify Controller data or Identify Namespace data.
When this type of data is being queried, fields in the STORAGE_PROTOCOL_SPECIFIC_DATA structure should have the following values:
NVMeDataTypeLogPageGet an NVMe log page.
When this type of data is being queried, fields in the STORAGE_PROTOCOL_SPECIFIC_DATA structure should have the following values:
NVMeDataTypeFeatureRetrieved by command - GET FEATURES or SET FEATURES
Corresponding values in STORAGE_PROTOCOL_SPECIFIC_DATA (get) or STORAGE_PROTOCOL_SPECIFIC_DATA_EXT (set):
NVMeDataTypeLogPageExRetrieved by command - GET LOG PAGE
When this type of data is being queried, fields in the STORAGE_PROTOCOL_SPECIFIC_DATA_EXT structure should have the following values:
NVMeDataTypeFeatureExRetrieved by command - GET FEATURES or SET FEATURES
When this type of data is being queried, fields in the STORAGE_PROTOCOL_SPECIFIC_DATA_EXT structure should have the following values:
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:
Allocate a buffer that can contains both a STORAGE_PROPERTY_QUERY and a STORAGE_PROTOCOL_SPECIFIC_DATA structure.
Set the PropertyID field to StorageAdapterProtocolSpecificProperty or StorageDeviceProtocolSpecificProperty for a controller or device/namespace request, respectively.
Set the QueryType field to PropertyStandardQuery.
Fill the STORAGE_PROTOCOL_SPECIFIC_DATA structure with the desired values. The start of the STORAGE_PROTOCOL_SPECIFIC_DATA is the AdditionalParameters field of STORAGE_PROPERTY_QUERY.
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:
Describes the type of NVMe protocol-specific data that's to be queried during an IOCTL_STORAGE_QUERY_PROPERTY request.
NVMeDataTypeUnknown:0Unknown data type.
NVMeDataTypeIdentifyIdentify 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.
NVMeDataTypeLogPageLog page data type.
NVMeDataTypeFeatureFeature data type.
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:
