Article
02/09/2023

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Applies a new set of hints to the LUN plex. Hints applied to a plex affect neither the LUN nor its other plexes.

Syntax

HRESULT ApplyHints(
  [in] VDS_HINTS *pHints
);

Parameters

[in] pHints

Pointer to the hints to be applied to the LUN plex. See the VDS_HINTS structure. Only fields relevant to a LUN plex are expected to be set; irrelevant fields are ignored.

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/value	Description
VDS_E_PROVIDER_CACHE_CORRUPT 0x8004241FL	This return value signals a software or communication problem inside a provider that caches information about the array. Use the IVdsHwProvider::Reenumerate method followed by the IVdsHwProvider::Refresh method to restore the cache.
VDS_E_OBJECT_DELETED 0x8004240BL	The LUN plex is no longer present.
VDS_E_OBJECT_STATUS_FAILED 0x80042431L	The LUN plex is in a failed state, and is unable to perform the requested operation.
VDS_E_ANOTHER_CALL_IN_PROGRESS 0x80042404L	Another operation is in progress; this operation cannot proceed until the previous operation or operations are complete.
VDS_E_NOT_SUPPORTED 0x80042400L	This operation or combination of parameters is not supported by this provider.

Remarks

Use the IVdsLunPlex::QueryHints method to get the current hints for the LUN plex.
