In AIX you do not need to wipe the OS completely. If you overwrite the first GB (or thereabouts) of the rootvgs hdisk device(s) with hexadecimal zeroes you will destroy the VGDA and upon reboot the VG will not be recognizable any more by the OS. This will prevent data recovery with "normal" measures offered by the OS, but it will perhaps not prevent specialized laboratories doing some "extreme" data recovery.
You will have to decide if you want to prevent only "normal" people from getting anything or if you need to even fool the NSA (which probably had your data even before you from tapping the wires ;-)) ).
I hope this helps.

NAME
tpconfig - Configure touchpad devices
SYNOPSIS
tpconfig [ OPTIONS ]
DESCRIPTION
This program can show or modify the configuration of several different kinds of touchpad devices, including most Synaptics TouchPad devices
and the ALPS Glidepad/Stickpointer.
Options for all touchpads:
--help Display a help summary and exit.
-D [N], --debug[=N]
Generate debugging output, where N of 1, 2, or 3 specifies the debugging level. If N is 0, debugging is turned off. If N is not
given, it defaults to 1.
-d DEVICE, --device=DEVICE
Use DEVICE as the device file for the mouse. If this option isn't given, the device file /dev/psaux is used.
--version
Display the version and copyright information and exit.
-i, --info
Display the current touchpad configuration.
-x, --reset
Perform a software reset on the touchpad.
Options for all Synaptics TouchPads:
-q, --quiet, --silent
Suppress verbose output.
-a [N] Display the packet mode. With argument N, set the packet mode, where N=0 means relative and N=1 means absolute.
--absolute
Set the packet mode to absolute.
--relative
Set the packet mode to relative.
-r [N], --rate[=N]
Display the reporting rate. With argument N, set the reporting rate, where N=0 means normal, and N=1 means high.
Options for older Synaptics TouchPads only:
-t [N], --tapmode[=N]
Display the tapping mode. With argument N, set the tapping mode, where N=0 means no tap gestures, and N=1 means tap and drag.
-s [N], --sleep[=N]
Display the sleep mode. With argument N, set the sleep mode, where N=0 means disable, and N=1 means enable.
Options for newer Synaptics TouchPads only:
-t [N], --tapmode[=N]
Display the tapping mode. With argument N, set the tapping mode, where N=0 means no tap gestures, N=1 means tap-to-click only, N=2
means tap and non-locking drag, and N=3 means tap and locking drag.
-2, --two-button
Set two-button mode.
-3, --three-button
Set three-button mode.
-c [N], --corner[=N]
Display the corner-tap mode. With argument N, set the corner-tap mode, where N=0 means disable, and N=1 means enable.
-e [N], --edgemode[=N]
Display edge motion. With argument N, set edge motion, where N=0 means never, N=1 means always, and N=3 means only during drag.
-m Display which mouse button is simulated by corner taps.
--middle-button
Make corner taps simulate the middle mouse button.
--right-button
Make corner taps simulate the right mouse button.
-z [N], --zthreshold[=N]
Display the z threshold setting (tap sensitivity). With argument N, set the z threshold setting to N.
--threshold[=N]
(Same as --zthreshold.)
Options for ALPS touchpads:
-r, --reset
Reset ALPS device.
-t [N], --tapmode[=N]
Display the tapping mode. With argument N, set the tapping mode, where N=0 means tapping disabled, and N=1 means tapping enabled.
EXAMPLES
Often it's desirable to disable tap mode, to prevent mouse events from being generated when the hand brushes the touchpad:
tpconfig --tapmode=0
