OA66750: RENAME FAILS IF SOURCE AND TARGET FILE ARE ON THE SAME VOLUME WITH GZD4030E ZDMF/K

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When using Logical Copy, and the target file is allocated on
  the same volume as the source file, the rename process at the
  end of Divert processing fails with message GZD4030E. Also,
  both source and target are inaccessible due to being
  incorrectly cataloged.

  ****************************************************************
  When users want to perform a migration of datasets, but keep
  them in the same STORGRP, failures occur because the Divert
  rename logic could not swap dataset names when they were on
  the same volume.  A related issue is that target dataset names
  can be either the new, processed dataset, or the old source
  dataset, and there is no obvious way to determine if the
  rename has been done when problems occur.
  

Problem conclusion

• The Divert rename process has been updated to this sequence:
  1. Create the target dataset with a last node of .T00000
  2. In Divert, the source dataset is renamed to the same as the
     target, except last node is .S00000
  3. Finally, the target dataset is renamed to the source dataset
     name.
  This avoids an attempt to have two datasets with the same name
  on the same volume (which would fail).
