The SetCHAPSharedSecret WMI method belongs to the unpublished MSiSCSI_Operations WMI class. For a description of the parameters of the SetCHAPSharedSecret method, see the member descriptions for the SetCHAPSharedSecret_IN and SetCHAPSharedSecret_OUT structures.
Miniport drivers that implement the MSiSCSI_Operations WMI class are not required to support SetCHAPSharedSecret.
