Error description

  • With version 7.1 server with node attribute "SPLITLARGEObjects"
    enabled,
    it can happen that "backup stgpool" can report success but not
    actually
    backup certain files to the copy storage pool.
    
    For example, running "backup stgpool" command, it can be
    seen that 6 items are reported as backed up successfully.

    These bitfiles are fragments in a Super Aggregate and all the
    fragments are not being backed up
    to the copy storage pool.
    
    "show invo" against these bitfiles will show that there is only
    a primary version
    and not a copy version.
    
    For example;
    
    show invo 24835425
