Error description

  • During a LAN-free restore or retrieve operation using
    storage agent version lower than 7.1 with a 7.1 server, there
    is no relevant message which would hint at the problem but the
    subsequent usage of the restored/retrieved object(s) may result
    in an unexpected behaviour. For example, a database application
    server may crash when accessing a restored data object.
    
    When reviewing backup/archive and restore/retrieve logs the size
    of an affected object will be smaller during
    restoring/retrieving than during the backup/archive operation.
    
    The problem does not occur if one of the following is true:
    - the Tivoli Storage Manager Server is at a level lower than
      7.1,
    - the storage agent is at a 7.1 level or higher,
    - data are restored or retrieved using the LAN,
    - The node attribute SPLITLARGEObjects on the Tivoli Storage
      Manager server was set to "No" (the default is "Yes") before
      the backup/archive operations.
    
    
    Tivoli Storage Manager versions affected:
    Server 7.1 on all platforms
    
    Initial Impact: High
    
    Additional Keywords:
    tsm71 tsm sta lanfree fragment
    

Local fix

  • 1) Upgrade the storage agent to a 7.1 level or higher.
    2) Update the node attribute SPLITLARGEObjects on the Tivoli
       Storage Manager server to "No" before running backup/archive
       operations.
    3) Restore or retrieve the data using the LAN only.

Problem conclusion

  • This problem was fixed.
    Affected platforms: AIX, HP-UX, Solaris, Linux and Windows.
    
    During a classic restore by using LAN-free data movement, if a
    fragmented
    file is processed, the restore fails with message ANR4629E.
    
    Message Text:
    ANR4629E Attempting to restore a
    fragmented file through a earlier-level storage
    agent, the file will not be restored: Node
    XXXX, Type Backup, File space XXXXXXXX, File
    name XXXXXX.
    
    Explanation:
    When the storage agent attempts to restore a fragmented file,
    the file is not restored.
    This behavior occurs during a classic restore by using a storage
    agent earlier than version 7.1.
    
    User Response:
    Complete one of the following actions to resolve the problem:
    Restore the file from LAN explicitly.
    Restore the file through a no-query restore.
    Upgrade the storage agent to a level at version 7.1 or later.
