Coupling Facility - channel status

Whenever there is an HCD IO activation to delete CF links from the CF LPARs, the channels are indeed deleted and no longer available for use, however somehow they remain on the CFCC and showing up on the zOS Display CF command outputs as follows : 

Coupling Facility: MZEXCF00 CHP NOT OPERATIONAL: D4 D5 F8 FA 

On this example, a CF named MZEXCF00 had these four channels removed - D4, D5, F8 and FA, however they still show up on the command output until a DEACT/ACT is performed on the CF LPAR. This is the current design and working as expected. 

It would be nice to have those channels removed from the displays so that automation that rely on the DISPLAY CF output could report actual unavailability of channels and raise a real alert by using  more accurate information instead of showing old channels that have already been removed from IODF.
