The following command changes the amount of memory that vxdmpadm can use to
accumulate the statistics:
# vxdmpadm iostat start memory=4096
The displayed statistics can be filtered by path name, DMP node name, and enclosure
name (note that the per-CPU memory has changed following the previous command):
# vxdmpadm iostat show pathname=c3t115d0
cpu usage = 8132us per cpu memory = 4096b
