hi,

For a realistic approach to measuring disk IO is best taking a sample in about 7-10 sec for sar whether it is for SAN Disk or local disks,look for the trend in all the values and find out which disk is busy

sar -d 7 100

Please do assaign pionts

Hi Wish,

You can use iostat,.

#iostat

device bps sps msps

c2t0d0 0 0.0 1.0
c10t2d7 0 0.0 1.0
c10t3d0 0 0.0 1.0
c10t3d1 0 0.0 1.0
c10t3d2 0 0.0 1.0
c10t3d3 0 0.0 1.0
c10t3d4 0 0.0 1.0

Check # man iostat for more details.

Hi Wish ,

Check with iostat bps (Kilobytes transferred per second. )

Example: If you would like to check for the disk ( c1t2d0)

# iostat 11 10 > iotest.data
# cat iotest.data | awk '{ print $2 }' | awk '{ R = R + $1} END { print "Current Data Transfer rate for : Disk [c1t2d0] =" R/10 "KB/sec" }'


Hope this will help ,
Cheers,
Raj.

Sorry missed one thing in first line , in my last post:

In first line grep for the 'disk' you want to check for io activity, and redirect:

# iostat 11 10 | grep c1t2d0 > iotest.data


Cheers,
Raj.
