Error description

  • MTF failed to recall HSM migrated dataset while trying to
    transfer from distributed platform to z/OS.
    Target agent trace shows following:
    c.i.w.io.zos.FTEDataset                        ----+----+ d
    generateDatasetAttributes data
    [com.ibm.wmqfte.io.FTEFileIOException: BFGIO0074W: An internal
    error has occurred.
    
                          The attributes for data set
    //'TARGET.DATASET' are not available, since the format-1 DSCB
    not available (data set could be on tape).
    
                          Additional information: OBTAIN DSN error
    RC=4 (0x4)]
     c.i.w.io.zos.FTEDataset                        ----+---- }
        generateDatasetAttributes returns [null] String
    
    This does not happen while transferring from z/OS to z/OS
    because the dataset attributes for source dataset will be used.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users of the MQ Managed File Transfer (MFT)
    on z/OS
    
    
    Platforms affected:
    z/OS
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    During MFT transfer, if the source agent is running on a
    non-z/OS platform and destination agent is running on z/OS
    platform, the transfer to destination dataset failed when the
    destination dataset was in migrated state.
    
    Destination agent threw the following RcException which was seen
    on the agent trace.
        com.ibm.jzos.RcException: OBTAIN DSN error RC=4 (0x4)
    MFT also reported : BFGIO0074W: An internal error has occurred.
    The attributes for data set //'SYS9.HMF.WZA.TRANSFER.TO11' are
    not available, since the format-1 DSCB not available (data set
    could be on tape). Additional information: OBTAIN DSN error RC=4
    (0x4) [com.ibm.wmqfte.io.FTEFileIOException] 	
    

Problem conclusion

  • MFT on z/OS has been updated such that when the destination
    dataset is detected to be in migrated state, the dataset is
    first recalled and transfer processing would continue only if
    recall is successful.
