Error description

  • In Tivoli Storage Manager server version 6.x, the cluster
    records that are used to track occupancy values for a given
    node may become invalidated such that occupancy values being
    reported are inaccurate. One result of this problem could be
    seen in the Query OCCupancy command where the Physical and
    Logical Space Occupied values are incorrect. Also, the Query
    STGpool F=D could show an incorrect value for Duplicate Data
    Not Stored.
    
    Another result of this problem is that a select on the occupancy
    table can report back NULL values for node names and filespace
    names. The example below shows valid output for TESTNODE1 but
    the second entry is missing both the node name and the filespace
    name:
    
    tsm>select * from occupancy
    NODE_NAME        TYPE      FILESPACE_NAME         STGPOOL_NAME
    --------------   -----     ------------------     ------------
    TESTNODE1        Arch      /tmp                   FILEPOOL
                     Bkup                             FILEPOOL
    
    This condition might be encountered when a node or filespace is
    deleted and the cluster tracking record is orphaned in the
    database.
    
    Customer/L2 Diagnostics:
    The following selects can be run to determine if there are
    NULL values:
    
    select * from occupancy where node_name is NULL
    select * from occupancy where filespace_name is NULL
