  *                      CMAS the CMAS will shut down and an     *

  ****************************************************************
  * RECOMMENDATION: After applying the PTF that resolves this    *
  *                 APAR, all CMASes and MASes must be recycled  *
  *                 to pick up the new code.  Note that regions  *
  *                 do not need to be brought down and restarted *
  *                 at the same time.                            *
  ****************************************************************
     The calculation used to determine whether CPSM can safely
  request an extension of a cache data space does not take into
  account the availability of Flash Express Storage Class Memory
  (SCM).  This could cause message EYUXC0021E to be issued incor-
  rectly if DASD paging space has been replaced by SCM.
  

Problem conclusion

•    Module EYU0XCCL (XCCL - Cache Auxiliary Storage Limit Verifi-
  cation) was updated to calculate the percent of total auxiliary
  storage currently in use correctly.
