Comments

• This APAR provides guest support for High Performance FICON
  for System z (zHPF).  zHPF is a performance and reliability,
  availability, and serviceability (RAS) enhancement of the
  z/Architecture and the FICON channel architecture implemented
  in the zEnterprise 196, zEnterprise 114, and System z10
  servers and the System Storage DS8000 series.  Exploitation
  of zHPF by the FICON channel, the operating system, and the
  control unit is designed to help reduce the FICON channel
  overhead.  When both the FICON channel and the control unit
  indicate support for zHPF, transport mode I/O is supported
  in addition to command mode I/O.  Use of zHPF requires the
  function to be installed on the machine (processor complex
  and channels) and the storage controller, and requires
  support in z/VM and the exploiting guest.
  
  The z/VM 6.2.0 publications at the z/VM web site
    http://www.vm.ibm.com/library/
  contain the publication changes for this support.
