IVdsServiceHba::QueryHbaPorts method

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Returns an IEnumVdsObject enumeration object containing a list of the HBA ports known to VDS on the local system.


HRESULT QueryHbaPorts(
  [out] IEnumVdsObject **ppEnum


ppEnum [out]

The address of an IEnumVdsObject interface pointer that can be used to enumerate the HBA ports as HBA port objects. For more information, see Working with Enumeration Objects. Callers must release the interface and each of the HBA port objects when they are no longer needed by calling the IUnknown::Release method.

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/valueDescription

The enumeration of HBA ports was returned successfully. If the local system has no HBA ports, the enumeration is empty.


VDS failed to initialize. If an application calls this method before the VDS service finishes initializing, the method is blocked until the initialization is complete. If the initialization fails, this error is returned.
