APAR status

  • Closed as program error.

Error description

  • File data corruption may occur on a target replication Server if
    deduplication is disabled for a storage pool and deduplicated
    files are subsequently moved from the storage pool (ie.
    migration).  This problem would only affect those objects that
    were deduplicated via the node replication process.  The problem
    condition does not apply to, or affect, deduplicated objects on
    the source replication Server.
    
    Platforms affected:
    All TSM 6.x Servers
    
    Additional Keywords:
    dedup duplication replicate target source
    

Local fix

  • Do not disable storage pool deduplication if deduped files
    exist.  To prevent further deduplication of incoming data,
    update the number of identification processes for the given
    storage pool to 0:
    
       update stgpool <stgpool name> identifyprocess=0
