Hi,

    I have a quick fix for this problem.

-       dsc->ipsd_disk.d_mediasize = totalsectors * IPS_BLKSIZE;

        device_printf(dev, "Logical Drive  (%dMB)\n",

    The (long long) casting might not be suitable on other
platform. It works for me on a dual XEON x225 box, which has a
ServeRAID 5i.
