IVdsIscsiTarget::QueryAssociatedLuns method (vds.h)
[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]
Returns a enumeration of the LUNs associated with the target.
Syntax
HRESULT QueryAssociatedLuns(
[out] IEnumVdsObject **ppEnum
);
Parameters
[out] ppEnum
The address of an IEnumVdsObject interface pointer that can be used to enumerate the LUNs as LUN objects. For more information, see Working with Enumeration Objects. Callers must release the interface and each of the LUN objects when they are no longer needed by calling the IUnknown::Release method.
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 |
|---|---|
|
The enumeration of associated LUNs was returned successfully. If the target has no associated LUNs, the enumeration is empty. |
|
The cache of the provider is corrupted. This indicates a software or communication problem inside a provider that caches information about the attached devices. The caller can use the IVdsHwProvider::Reenumerate method followed by the IVdsHwProvider::Refresh method to restore the cache. |
|
The target object is no longer present. |
|
Another operation is in progress; this operation cannot proceed until the previous operations are complete. |
Remarks
LUNs are associated with the target by calling the IVdsLunIscsi::AssociateTargets method.
