The performance optimization function is capable of estimating an effect of load distribution after logical
disk movement. By executing this function, the changes of Busy Ratios for RANKs/pools to which source
and destination logical disks belong are displayed in graphs. A volume that cannot be replaced is not
displayed in a graph.
If you log into the system to which the partitioning function is installed as a partition user, only the
resources of the partitions the user can manage can be displayed in graphs.
This section describes the dialog for displaying an effect of replacement and the displaying procedures.
