IVdsLun::GetSubSystem

-description

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Returns the subsystem that surfaces the LUN.

-parameters

-param ppSubSystem [out]

The address of an IVdsSubSystem interface pointer. Callers must release the interface.

-returns

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.
