The following examples show how to set limits using the SET
    subcommand and its qualifiers.

    1.

    $ DEFRAGMENT SET PROCESS_LIMIT=3, IO_LIMIT=14/NODE=NODE_1

    In this example, the maximum number of defragmentation processes
    that can occur on NODE_1 is three. Further, a restriction
    of 14 direct I/Os per second is placed on each of these three
    defragmentation processes.

    2.

    $ DEFRAGMENT SET CPU_LIMIT=50

    In this example, the maximum CPU percentage allocated to any
    defragmentation process is set to 50 percent on all nodes in
    the system. If a defragmentation process exceeds this limit,
    its priority is decremented each minute (approximately) until it
    reaches that specified by the /PRIORITY qualifier or three..
