Need command to display path utilization
We are currently moving from a dmx to a clariion.
We are trying to determine if we need powerpath.....in doing so I need a unix command that will show current path utilization.
Can anyone help me with this?
Thanks in advance for your help

iostat -d hdisk57 5
System configuration: lcpu=2 disk=24
" Disk history since boot not available. "
Disks: % tm_act Kbps tps Kb_read Kb_wrtn
hdisk57 0.0 0.0 0.0 0 0
hdisk57 0.0 0.0 0.0 0 0
hdisk57 0.0 0.0 0.0 0 0
