IVdsHwProvider::Refresh method (vdshwprv.h)

  • Article

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Refreshes VDS's internally cached data about existing subsystems that are managed by VDS providers.

Syntax

HRESULT Refresh();

Return value

This method can return standard HRESULT values, such as 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_STATUS_FAILED
0x80042431L
 The provider 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_INITIALIZE_NOT_CALLED
0x80042402L
 The initialization method has not been called.

Remarks

VDS maintains a cache of information about the properties of all VDS objects, such as subsystems and controllers. Whenever a change occurs that triggers a notification, this cache is updated. In cases where the cache is not being updated properly, applications can call this method to refresh the cache. Note that calling this method to refresh the cache can in turn trigger additional notifications.

This method does not query the network to find newly connected subsystems. To discover newly connected and disconnected subsystems, use the IVdsHwProvider::Reenumerate method.
