Error description

  • A problem with VM's CCW translation causes a guest's IO
    operation to fail with a command reject. In the submittor's
    case a zOS guest IO operation fails and zOS issues the following
    error message:
     IOS000I 7100,FF,CMD,E7,0200,,00000001,SW7100,RLSRDR00,
    SENSE:
    80000000000000000000000000000000
    000000000000ED0F00000040E2000000
    The GTF trace for zOS, shows a X'E7' CCW failed with unit check
    status and a residual byte count of X'44'.
     zOS' CCW string:
    E7600044 04F6ADA4
    08000000 0ADA0540
    47400010 06AE094C
    2960002C 06AE0314
    03200001 00000000
    05000060 001A5528
     zVM translated the above string to:
    63400018 05DE5148
    30200044 05CE1428

     HCPFTR, fast translation processing, fails to clear
    IORBK fields related to the E7 CCW while aborting fast
    CCW translation. The result is incorrect CCW translation
    in the long path.
    

Problem conclusion

  •  HCPFTR abort processing has been changed to clean up IORBK
    fields related to the fast translation of the E7 CCW.
