Displaying cumulative I/O statistics
Use the groupby clause of the vxdmpadm iostat command to display cumulative
I/O statistics listings per DMP node, controller, array port id, or host-array
controller pair and enclosure. If the groupby clause is not specified, then the
statistics are displayed per path.
To group by DMP node:
# vxdmpadm iostat show groupby=dmpnode [all | dmpnodename=dmpnodename
| enclosure=enclr-name]
To group by controller:
# vxdmpadm iostat show groupby=ctlr [ all | ctlr=ctlr ]
For example:
# vxdmpadm iostat show groupby=ctlr ctlr=c5

To group by arrayport:
# vxdmpadm iostat show groupby=arrayport [ all | pwwn=array_pwwn
| enclosure=enclr portid=array-port-id ]
For example:
# vxdmpadm iostat show groupby=arrayport enclosure=HDS9500-ALUA0 \

For example:
# vxdmpadm iostat show groupby=enclosure enclosure=EMC_CLARiiON0
