Error description

  • Not all code paths were corrected by apar PH15741, it was
    discovered that this job creation or update may not correctly
    set up the bits in line with the new Safe Guard copy
    specifications which will cause the FCM program fail with I/O
    ERROR. MSG FRMT = 0, MSG NMBR = 4, REAS: 00
    
    
    FCM Apar PH42291 - additional note
    A variation of this apar is still exposed to the issue and was
    recently reported. With PTF UI78254 applied on top of FCM 6.3.0
    The F1 dataset may still have an
    extraneous character in the parms that is now re-purposed for a
    SafeGuarded setting and no longer
    valid for Flash Copy configurations:
    
    in DATASET *.TEMPC.JOBS
    PARM='FCEST,F1=102E59
    
    the correct value can be found in the *.NEW.JOBS
    PARM='FCEST,F1=002E59
    
    The JCLS are copied from *.TEMPC.JOBS by the D@SWITCH JCL into
    *.NEW.JOBS
    PARM='FCEST,F1=102E59
    
    The first order byte needs to be set to 00 in order for the
    FlashCopy JOB to work correctly.
    
    Corrective action is not in plan at this time.  Clients should
    consider migrating their FlashCopy
    Management to the new Technical direction which is a product
    called Copy Services Manager.
    
    As of Copy Services Manager 6.2.10 support is available for
    loading a Flash copy session into
    the native zOS environment using a session property "z/OS
    Management option". Please see the IBM
    Copy Services Manager 6.2.10 and up documentation in Knowledge
    Center for more details.
