IC82573: ANR4895E DEDUPLICATED LINKS BEING INVALIDATED

APAR status

• Closed as program error.

Error description

• The Tivoli Storage Manager server is deallocating target
  chunks and not replacing the chunks appropriately. Any
    object that was linked to these chunks become invalid. The
    links can be invalidated under the following conditions:
  
    Data Movement
      - A file is deduplicated in a primary storage pool.
      - That file is moved to a new primary storage pool.
      - The file has at least one base chunk that must remain
        in the initial primary storage pool due to dependents.
      - The file is moved back to the initial primary storage
        pool where the base chunks still reside.
    Data Copy
      - A file is deduplicated in a primary storage pool.
      - That file is moved to a new primary storage pool after
        being copied to a copy storage pool.
      - The file has at least one base chunk that must remain
        in the initial primary storage pool due to dependents.
      - The file is then restored back to the initial primary
        storage pool where the base chunks still reside.
