Temporary fix

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.
