Error description

  • Under certain data movement scenarios within the Tivoli Storage
    Manager server, deduplicated data may not be flagged
    appropriately such that it is managed correctly. If a
    deduplicated object is not managed correctly it may cause
    dependent extents (dependents) to become invalidated. The data
    movement that may cause this is restore stgpool from a
    deduplicated storage pool, or moving data out of a deduplicated
    storage pool into a non-deduplicated storage pool and then back
    into a deduplicated storage pool.
    .
    .
    Customer/L2 Diagnostics:
    The problem does not show up immediately when the data is been
    moved. It can be around for a longer time (depends on various
    variables like expiration, data movement, ...) until it shows up
    when the data is being referenced.
    .
    The key message to look for in the ACTLOG is:
    ANR4895E Deduplicated bitfile <BITFILE_ID> on volume
    <VOLUME_NAME> has invalid links
    .
    .
    Tivoli Storage Manager Versions Affected:
    Tivoli Storage Manager Server Versions 6.1 on all platforms
    .
    .
    Initial Impact:
    High

    .
