[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Enables VDS to determine whether the hardware provider manages the specified LUN.

Syntax

HRESULT QueryIfCreatedLun(
  [in]  LPWSTR              pwszDevicePath,
  [in]  VDS_LUN_INFORMATION *pVdsLunInformation,
  [out] VDS_OBJECT_ID       *pLunId
);

Parameters

[in] pwszDevicePath

A pointer to the path to the LUN on the local computer; a zero-terminated, human-readable string.

[in] pVdsLunInformation

A pointer to the identification data of the specified LUN. See the VDS_LUN_INFORMATION structure.

[out] pLunId

A pointer to the returned LUN GUID. If the provider does not manage the LUN, set this parameter to GUID_NULL.

Return value

This method can return standard HRESULT values, such as E_INVALIDARG or E_OUTOFMEMORY, and VDS-specific return values. It can also return converted system error codes using the HRESULT_FROM_WIN32 macro. Errors can originate from VDS itself or from the underlying VDS provider that is being used. Possible return values include the following.

Return code	Description
S_OK	The provider owns the LUN; returns the GUID of the LUN.
S_FALSE	The provider does not own the LUN.

Remarks

Only VDS calls this method.
