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[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Applies a new set of hints to the LUN. Hints that are applied to a LUN are simultaneously applied to all plexes.

Syntax

HRESULT ApplyHints(
  [in] VDS_HINTS *pHints
);

Parameters

[in] pHints

A pointer to the new hints to be applied to the LUN. See the VDS_HINTS structure.

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 object is no longer present.
VDS_E_OBJECT_STATUS_FAILED
0x80042431L
The LUN is in a failed state and 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

Instead of using this method, callers can specify hints by passing in the pHints parameter to the IVdsSubSystem::CreateLun method when creating a LUN. Use the IVdsLun::QueryHints method to query for existing hints.
