IVdsLun::QueryPlexes method (vdshwprv.h)

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Returns an enumeration of the plexes in a LUN.

Syntax

HRESULT QueryPlexes(
  [out] IEnumVdsObject **ppEnum
);

Parameters

[out] ppEnum

The address of an IEnumVdsObject interface pointer that can be used to enumerate the plexes as LUN plex objects. For more information, see Working with Enumeration Objects. Callers must release the interface and each of the LUN plex 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.

Remarks

All LUNs must have at least one plex; mirrored LUNs have multiple plexes.
