IVdsLun::QueryHints method (vds.h)
Returns the hints currently applied to the LUN.
HRESULT QueryHints( [out] VDS_HINTS *pHints );
A pointer to the returned LUN hints. See the VDS_HINTS structure.
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.
||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.|
||The LUN object is no longer present.|
||The LUN is in a failed state and is unable to perform the requested operation.|
||Another operation is in progress; this operation cannot proceed until the previous operation or operations are complete.|
||This operation or combination of parameters is not supported by this provider.|
Callers can specify hints by passing in the pHints parameter to the IVdsSubSystem::CreateLun method when creating a LUN or by using the IVdsLun::ApplyHints method to apply a set of new hints to an existing LUN.
