This structure is used in conjunction with IOCTL_STORAGE_QUERY_PROPERTY to retrieve the properties of a storage device or adapter.
PropertyIdIndicates whether the caller is requesting a device descriptor, an adapter descriptor, a write cache property, a device unique ID (DUID), or the device identifiers provided in the device's SCSI vital product data (VPD) page. For a list of the property IDs that can be assigned to this member, see STORAGE_PROPERTY_ID.
QueryTypeContains flags indicating the type of query to be performed. For a list of the various query types that can be assigned to this member, see STORAGE_QUERY_TYPE.
AdditionalParametersContains an array of bytes with additional input parameters that are needed for the PropertyId query. Not all PropertyId values require additional input parameters.
The results of the query can be one of several structures depending on the value of the PropertyId member. These values are enumerated by the STORAGE_PROPERTY_ID enumeration.
If the QueryType member is set to PropertyExistsQuery, then no structure is returned. For more info, see STORAGE_QUERY_TYPE.
Indicates the properties of a storage device or adapter to retrieve as the input buffer passed to the IOCTL_STORAGE_QUERY_PROPERTY control code.
PropertyIdIndicates whether the caller is requesting a device descriptor, an adapter descriptor, a write cache property, a device unique ID (DUID), or the device identifiers provided in the device's SCSI vital product data (VPD) page. For a list of the property IDs that can be assigned to this member, see STORAGE_PROPERTY_ID.
QueryTypeContains flags indicating the type of query to be performed as enumerated by the STORAGE_QUERY_TYPE enumeration.
| Value | Meaning |
|---|---|
| PropertyStandardQuery 0 |
Instructs the port driver to report a device descriptor, an adapter descriptor or a unique hardware device ID (DUID). |
| PropertyExistsQuery 1 |
Instructs the port driver to report whether the descriptor is supported. |
AdditionalParametersContains an array of bytes that can be used to retrieve additional parameters for specific queries.
The optional output buffer returned through the lpOutBuffer parameter of the IOCTL_STORAGE_QUERY_PROPERTY control code can be one of several structures depending on the value of the PropertyId member. If the QueryType member is set to PropertyExistsQuery, then no structure is returned.
