    iostat -En - odd ouput for DVD drive

    807559
      I'm experiencing a bit of an odd issue with a couple of servers and iostat.

      host1:root> iostat -En

      If I mount a DVD the problem goes away.

      host1:root> mount -F hsfs -o ro /dev/dsk/c2t0d0s2 /cdrom

      However, as soon as I unmount the DVD the problem re-occurs.

      Any ideas?

          Seems to be "normal"
