A typical output of sar command
-------------------------------

08:56:22 bread/s lread/s %rcache bwrit/s lwrit/s %wcache pread/s pwrit/s
device %busy avque r+w/s blks/s avwait avserv
08:56:23 0 53 100 4 5 20 0 0

08:56:24 0 4 100 1 4 75 0 0

08:56:25 0 2 100 2 1 0 0 0

08:56:26 0 4 100 5 2 0 0 0
c2t6d0 2.00 0.50 7 56 0.42 3.15
08:56:27 0 14 100 4 6 33 0 0

bdf output is as follows
--------------------------
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 512000 328988 172284 66% /

I need to find the output of sar against the above logical file systems instead of physical partition c2t6d0

something like this
Filesystem Reads Writes Transfers
/dev/vg00/lvol3 400 300 700

Please suggest how do i do that
