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.
