IVdsIscsiTarget::QueryPortalGroups method (vdshwprv.h)

[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Returns an enumeration of the iSCSI portal groups within the target.

Syntax

HRESULT QueryPortalGroups(
  [out] IEnumVdsObject **ppEnum
);

Parameters

[out] ppEnum

The address of an IEnumVdsObject interface pointer that can be used to enumerate the portal groups as portal group objects. For more information, see Working with Enumeration Objects. Callers must release the interface and each of the portal group 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
S_OK
The enumeration of portal groups was returned successfully. If the target has no portal groups, the enumeration is empty.
VDS_E_PROVIDER_CACHE_CORRUPT
0x8004241FL
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.
