Error description

  • RMF used by z/OS running as a guest of z/VM with VM66532 will
    fail if the VMGUEST RMF option is in effect.
    In this environment, RMF will fail, and z/OS may take SVC dumps
    and ultimately return with a non-zero completion code with a
    return code reflecting the interruption encountered by RMF. The
    RMF failure is caused by an error in the way z/VM formats a
    diagnose x'204' response buffer. To avoid RMF failure, ensure
    the NOVMGUEST RMF option is in effect. If RMF is not running,
    ensure VMGUEST is not specified in any ERBRMFxx parmlib members
    for a Monitor I data gatherer session. By default, the
    NOVMGUEST option is used by RMF when the NOVMGUEST or VMGUEST
    options are not specified by any parmlib members. If RMF is
    running, the option can be queried using the 'F RMF,D ZZ'
    console command. If the VMGUEST option is present, the 'F
    RMF,F ZZ, NOVMGUEST' console command can be used to change the
    setting dynamically.
    

Local fix

  • To avoid RMF failure, ensure the NOVMGUEST RMF option is in
    effect. If RMF is not running, ensure VMGUEST is not specified
    in any EBRMFxx parmlib members for a Monitor I data gatherer
    session. If RMF is running, the option can be queried using the
    'F RMF,D ZZ' console command. If the VMGUEST option is present,
    the 'F RMF,F ZZ,NOVMGUEST' console command can be used to change
    the setting dynamically.
