IC90390: SOME DATA MOVEMENT SCENARIOS MIGHT RESULT IN INVALIDATED DEDUPLICATION LINKS - ANR4895E

APAR status

• Closed as program error.

Error description

• In cases where data which initially exists in a deduplicated
  pool, is moved out of that pool to another pool (deduped or not)
  and then is moved back into the original pool, invalidated links
  may result. The invalidated links will surface with the ANR4895E
  message which is issued when the files, that own
  the invalidated links, is attempted to be moved or copied.
  ANR4895E Deduplicated bitfile XXXXXXXXX on volume
  /xxxxx/xxxxx.bfs has invalid links.
  
  Any subsquent attempt to move, or copy, that file will result in
  a message indicating that the file(s) has been marked as damaged
  - ANR1165W.
  Customer/L2 Diagnostics (if applicable)
  If the data movement scenario, as described above, has been
  encountered, the VALIDATE EXTENTS utility can be used
  to proactively check for invalidated links. This utility will
  check for invalidated links, and if found, will mark the file(s)
  as damaged such that they can be restored from an available
  copy pool.

  is available, will need to be deleted.
