io by filesystem??

I'm wanting to drill down one level deeper that iostat. For example, for the following iostat output, I'd like to now understand the io for hdisk2 by filesystem:

Disks: % tm_act Kbps tps Kb_read Kb_wrtn
hdisk3 4.7 1792.0 80.7 0 5376
hdisk1 7.0 1997.3 95.3 80 5912
hdisk2 8.3 2962.7 85.7 4148 4740

Another question, is there a way to easily list all filesystems related to a given hdisk??

I dont know which OS you are using, so am not sure if this will work on your system. Try using iostat with the '-xnp' of '-xnP' options. Throw in '-m' if you want the mount point.

Thanks for the reply. OS is AIX 5.3 The '-xnp' and '-xnP' parms are not available.
