Error description

  • If a filespace containing data from a deduplicated storage pool
    is deleted, there is the potential for some of the data to be
    base chunks for deduplicated chunks that still resides in other
    filespaces on the server. Because these base chunks must remain
    on the server select from occupancy output still sees them.
    However because no filespace exists that owns them from the
    original client perspective the output from the select will show
    "DELETED" as the filespace name. If the node this data belonged
    to was also deleted then the node name in the select occupancy
    output will also show "DELETED". Use of this "DELETED" value for
    filespace and node names was added with the fix for FIN APAR
    IC90010 that was put into the 7.1.0 server level.  The Tivoli
    Storage Manager documentation needs to be updated to reflect
    that fact that at 7.1 and above select from occupancy can return
    this "DELETED" value for filespace and nodename under the given
    circumstances.
    Tivoli Storage Manager Versions Affected: 7.1 all platforms
    
    Initial Impact: Low
