Error description

  • After a Celerra NAS 'filespace' or 'path' is renamed in
    VIRTULASFSMAPPING configuration on the Tivoli Storage
    Manager Server, using "UPDATE VIRTUALFSMAPPING",
    the NAS data cannot be restored to the EMC
    Celerra filer. During restore, Tivoli Storage Manager provides
    the Celerra filer with the current filesystem name as it exists
    in the Tivoli Storage Manager database. The EMC Celerra filer
    will check the
    original file system name during restore. If the name provided
    by Tivoli Storage Manager does not match the original file
    system name, nothing is restored, no errors are reported in the
    activity log,
    and the "restore node" or "restore nas" process reports as being
    sucessful.
    So, "UPDATE VIRTUALFSMAPPING"
    should be prohibited for NAS nodes associated with EMC Celerra
    filers.
    
    This is similar to APAR IC96936:
    http://www-01.ibm.com/support/docview.wss?uid=swg1IC96936
    which addressed the 'rename filespace' command.
    
    
    
    
    Tivoli Storage Manager Server Versions Affected:  6.3.x and
    7.1.x on all supported platforms
    
    
    
    
    Initial Impact: Medium
    
    Additional Keywords:  TSM emc celerra ndmp restore IC96936
    virtualfs virtualfsmapping
    

Local fix

  • Update the virtual filespace mapping with the original values
    for filespace and path. If the original values for the filespace
    and path in the
    virtual filespace definition are not available contact
    support."

    ****************************************************************
    If you cannot restore your Celerra or VNX NAS data because of
    changes to the virtual file space mapping, use the following
    procedure to recover your data:
    
     1. Identify the original file system and path for the data when
    it was backed up. If you cannot identify the original file
    system and path, contact IBM Support.
     2. Save the current settings for the file system and path of
    the virtual file space mapping.
     3. Update the virtual file space mapping with the original file
    system and path settings by specifying the FORCE=YES parameter
    of the UPDATE VIRTUALFSMAPPING command.
     4. Recover the data.
     5. Update the virtual file space mapping with the current file
    system and path settings that were saved in step 2 by specifying
    the FORCE=YES parameter of the UPDATE VIRTUALFSMAPPING
    

Problem conclusion

  • This problem was fixed.
    Affected platforms:  AIX, HP-UX, Solaris, Linux, and Windows.
