Note:
Depending on the amount of I/O and the rate or duration of the data
transfer, overflow of the buffers containing this data can occur. In this case,
the overflow is marked with “#######”, as shown in the example below. If
this occurs, you may want to zero out the counters by using the clear
command, “/cx/px set dpmstat=clear [type=ra|lct|ext]” on page 106.
