    Hi All,

    I am trying to determine disk utilization using the "iostat" command.

    bash-2.03# iostat -n -M -D 2 5
           c0t0d0 c0t1d0 c0t6d0
     rps wps util rps wps util rps wps util
       1 0 0.5 1 0 0.3 0 0 0.0
       0 0 0.0 0 0 0.0 0 0 0.0
       0 1 1.1 0 0 0.0 0 0 0.0
       0 0 0.0 0 0 0.0 0 0 0.0
       0 0 0.0 0 0 0.0 0 0 0.0

    How do I know how much utilization, rps, and wps are good/acceptable?

    This is a 36GB SCSI disk on an E220.

    Thanks,
    Anjan
