TPIO

The TPIO (TPI) service displays all outstanding I/O, including TP devices.

This service also determines if TP lines are enabled (have outstanding I/O).

Syntax

GUID-2AA2CD22-895B-4559-9B26-E352344A4631-low.pngThe parameters are defined as follows:

Parameter

Description

dvn

is the device number for which outstanding I/O is to be displayed

volser

is the volume serial number for which outstanding I/O is to be displayed
