Error description

  • REQUEST REJECTED:<jobname>, <unit>,<reason> <dsname>
    
    Error encountered after a data set associated with a zDMF
    Migration Group in MIRROR was deleted followed by the internal
    deletion of the corresponding target data set. Subsequent
    processing may result in an allocation in the same extent
    location where the target file resided so requests to write to
    these tracks are rejected incorrectly.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: All zDMF users.                              *
    ****************************************************************
    * PROBLEM DESCRIPTION: A data set being migrated is deleted    *
    *                      on one system.  The target data set     *
    *                      related to the deleted data set is      *
    *                      also deleted.  Subsequent to the        *
    *                      deletion, the DASD space formerly       *
    *                      occupied by the target data set is      *
    *                      reallocated to a new data set.          *
    *                      On a system where the original          *
    *                      delete did NOT occur, when I/O is       *
    *                      attempted to the new data set, zDMF     *
    *                      may reject that I/O issuing message     *
    *                      GZD3311I.  zDMF interprets the I/O      *
    *                      as an interloper on a target            *
    *                      data set.                               *
    ****************************************************************
    * RECOMMENDATION: Apply PTF and WARM start.                    *
    ****************************************************************
    zDMF rejects I/O directed at DASD space formerly allocated
    to a deleted target data set.
    

Problem conclusion

  • GZDDBHB is modified to mark the extent descriptor control
    blocks (DWEXT) deleted whenever a data set being migrated
    is deleted.
