IVdsLun::Recover method (vdshwprv.h)

Article
02/22/2024

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Starts a recovery operation on a LUN.

Syntax

HRESULT Recover(
  [out] IVdsAsync **ppAsync
);

Parameters

[out] ppAsync

The address of an IVdsAsync interface pointer. Callers must release the interface. Use this interface to cancel, wait for, or query the status of the operation.

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 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_INVALID_OPERATION 0x80042415L	This LUN is not fault tolerant; a recovery operation is not possible.

Remarks

The recovery operation entails mirror resynchronization, parity regeneration, or substitution of a spare drive for a failing drive. Most subsystems initiate recovery operations automatically. However, for those that do not, this method provides a means by which to initiate recovery manually.
