VDS_E_INITIATOR_ADAPTER_NOT_FOUND

This HRESULT is tied to path endpoint identity. VDS_PATH_INFO represents a LUN path and, for an iSCSI path, carries an initiatorAdapterId on the local endpoint. If the provider or service returns a path whose adapter object no longer exists in the current VDS view, GetPathInfo cannot build a coherent endpoint description.

Why this state matters

The missing object should not be inferred from the IP address alone. The initiator adapter is a VDS object, while the initiator portal address is another piece of path information. Adapter removal, stale provider cache, or a race with device reconfiguration can invalidate the object ID even when an interface address still exists.

Diagnostic focus

Capture the path ID and initiator adapter object ID from the failing path information.
Re-enumerate IVdsServiceIscsi::QueryInitiatorAdapters and compare the returned object IDs with the path endpoint.
Check recent HBA/initiator service and Plug and Play changes before editing target configuration.
Refresh or re-enumerate provider state and reacquire the LUN/path objects instead of continuing to use stale COM object references.
