[Beginning with Windows 8 and Windows Server 2012, the Virtual Disk Service COM interface is superseded by the Windows Storage Management API.]

Associates LUNs with subsystem iSCSI targets.

Syntax

HRESULT AssociateTargets(
  [in] VDS_OBJECT_ID *pTargetIdArray,
  [in] LONG          lNumberOfTargets
);

Parameters

[in] pTargetIdArray

A pointer to an array of target VDS_OBJECT_ID data types. The provider associates these iSCSI targets with the LUN. This array includes targets already associated with the LUN that are to remain so.

[in] lNumberOfTargets

The number of targets specified in the pTargetArray parameter.

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_OBJECT_NOT_FOUND 0x80042405L	Can be returned from any method that takes a VDS_OBJECT_ID constant. This return value indicates that the identifier does not refer to an existing object.
VDS_E_NOT_SUPPORTED 0x80042400L	This operation or combination of parameters is not supported by this provider.

Remarks

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

Use the IVdsLunIscsi::QueryAssociatedTargets method to query target associations. Use the IVdsIscsiTarget::QueryAssociatedLuns method to query the LUNs associated with a target.
