Error description

  • When replicating inactive data that has no active version it can
    become the active version on the target server.  This happens
    when the data was deactivated on a Tivoli Storage Manager 6.3
    server and this data is replicated from a 7.1.x, to another
    7.1.x server.  The data becomes the active version on the end
    target server.  This only happens when DISSIMILAR POLICIES is
    enabled.
    
    This will be seen in two scenario's:-
    
    1) Replicate Node from 6.3.x server to server version 7.1.1 or
    higher and to a second server at 7.1.1 or higher
    
    OR
    
    2) Upgrade 6.3.x server to version 7.1.1 (or higher) and then
    replicate to another 7.1.1 (or higher) server.
    
     This could occur when using dissimilar policies, both source
    and target servers are 7.1.1 or higher and the source server
    contains files backed up and deactivated while at 6.3.x.
    
    
    Customer/L2 Diagnostics:
    
    This can be recreated using the following steps:-
    
    Server A - 6.3.x
    Server B & C - 7.1.x
    
    - backup a directory to server A
    - delete a file from the directory and backup again
    - replicate from server A  to server B
    - Issue REMOVE REPLNODE on server B to break the pair with A
    - replicate from server B to server C
    
    Example:
    After this sequence, with DISSIMILAR POLICIES (DP) enabled, the
    file on server C was active.
    With DISSIMILAR POLICIES disabled, the file on server C was
    still inactive.
    
    DP   A (6.3.x) -> B (7.1.4) -> C (7.1.4)
    Yes  Inactive     Inactive      Active
    No   Inactive     Inactive     Inactive
    
    Tivoli Storage Manager Versions Affected:    7.1.1 and higher on
    all supported platforms

Local fix

  • Disabling DISSIMILAR POLICIES  should allow the data to be
    replicated and remain inactive.
