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.

Local fix

    restored from the copy storage pool or, if no copy storage pool
    is available, will need to be deleted.
