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[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Returns an enumeration of currently associated iSCSI targets—the targets through which the LUN is accessible.

Syntax

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

Parameters

[out] ppEnum

The address of an IEnumVdsObject interface pointer that can be used to enumerate the iSCSI targets as target objects. For more information, see Working with Enumeration Objects. Callers must release the interface and each of the target 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
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.

Remarks

Most subsystems implement only one associated target per LUN, but some allow for multiple associated targets.

Use the IVdsLunIscsi::AssociateTargets method to associate the target. Use the IVdsIscsiTarget::QueryAssociatedLuns method to query the LUNs associated with a target.
