Problem conclusion

• Enhancement:
  For z/OS V2R1, V2R2 and V2R3 HCM, this APAR offers:
  
  The device suppliers can describe the device capabilities in
  Unit Information Module(UIM).  Currently, UIM is enhanced to
  allow device suppliers to specify whether the device can be
  located in an alternative subchannel set and whether that
  device in the alternative subchannel set is then supported
  by z/OS or z/VM (This is NOT included in this APAR).
  Applying this APAR, HCM is enhanced to recognize the
  information from HCD and act accordingly.
  
  It is recommended to install the HCD PTFs for
  APAR OA54709 first.
