For protocol-specific data, use the STORAGE_PROTOCOL_SPECIFIC_DATA structure in the AdditionalParameters field. Use the AdditionalParameters field to specify more details, depending on the type of data.
In the PropertyId filed, use the STORAGE_PROPERTY_ID enumeration to specify the type of data. STORAGE_PROPERTY_QUERY : This structure includes the PropertyId and AdditionalParameters fields to specify the data to be queried. For more info, see Protocol-specific queries and Temperature queries. IOCTL_STORAGE_QUERY_PROPERTY : Use this IOCTL with the STORAGE_PROPERTY_QUERY structure to retrieve device information. STORAGE_PROTOCOL_STATUS_INVALID_REQUEST.STORAGE_PROTOCOL_COMMAND : This input-buffer structure includes a ReturnStatus field that can be used report the following status values. For more info, see Pass-through mechanism. You can use it with vendor-specific commands. This IOCTL enables NVMe pass-through and supports the Command Effects log in NVMe. IOCTL_STORAGE_PROTOCOL_COMMAND : Use this IOCTL with the STORAGE_PROTOCOL_COMMAND structure to issue NVMe commands. For more information about header files, see Header files. These APIs can be found in winioctl.h for user mode applications, and ntddstor.h for kernel mode drivers. You can use the following general-use APIs to access NVMe drives in Windows 10. How to perform behavior changing commands, such as setting temperature thresholds.How to obtain temperature information from an NVMe drive.How to send an Identify, Get Features, or Get Log Pages command to the NVMe drive.How to send a vendor-specific NVMe command with pass-through.This topic provides an overview of general-use APIs that you can use to access NVMe drives in Windows 10. In Windows 10, several new features were introduced, including a pass-through mechanism for vendor-specific NVMe commands and updates to existing IOCTLs. It's also available to Windows 7 devices through a KB hot fix. Device access is enabled via StorNVMe.sys, the in-box driver first introduced in Windows Server 2012 R2 and Windows 8.1. Learn how to work with high-speed NVMe devices from your Windows application.
