Jared - Which system is that? I tried it on Solaris and Tru64, but it wasn't there.

vxprint can be used to determine which drives make up a filesystem.

Can anyone direct me to a method or tool for checking I/O on filesystems.

the problem lies with matching up device names given by iostat to filesystem
mount point names given by df.

I.e.
iostat -xdn

                              extended device statistics 
  r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device .
  0.6  2.5   23.0   20.1  0.0  0.0    0.0   14.1   0   4 c3t5d4
  3.0  2.1   22.1   17.4  0.0  0.1    0.0   11.6   0   3 c2t4d0
  3.0  1.5   22.1   17.1  0.0  0.0    0.1    8.3   0   2 c1t0d0
.
(or iostat -x shows devices as 'ssd34'.)

I have Solaris 2.7 , veritas volume manager with non journalled filesystems.

I'm afraid that I have not been able to keep up with Unix sys admin skills since I looked after SunOS 4.1.3 , HP-UX 9.7/10 and Apollo DomainOS workstations.

Regards,
Mike.
