symstat output

I am trying to find out the IO/Sec and through put for a particualr lun real time, With symstat command i am gettin the below output.

          DEVICE                   IO/sec        KB/sec     % Hits   %Seq     Num WP

10:23:13                       READ  WRITE    READ  WRITE  RD  WRT  RD  WRT  Tracks

                                                                                  

10:23:19 1234 (Not Visible )     29     44     321     413  14 100    0   0   1721

The device 1234 (480 GB) is a eight member meta head (8*60 GB). Now my question is,

Is the IO and other details showing in the above output is for the entire Meta or is it just for the member?
