First off, welcome to the AIX board.
Having said this, it might help to describe your hardware a bit more in detail. The more detail you give the better the offered solutions will be.
In general (but this will depend on your hardware, so take this cum grano salis) it will not be necessary to power off or even unmount filesystems involved. AIX' LVM and IBMs RAID driver can handle practically all the necessary tasks while the storage is in use. I wouldn't start the biggest database import available while recovering from disk failures but that's about it.
I have not used RAID arrays for probably 10 years now, so i can only draw on some remote memory, but IBMs arrays always included hot-standby-disks. A failed disk is immediately swapped with the standby and you take the former out and bring in a new standby disk in when recovering the array.
I hope this helps.

Hey everyone,
first of all, this is the motherboard I have: GigaByte GA-K8NXP-9 , nForce4 Ultra. It supports RAID 0, 1, 0+1 apparently both on the IDE and S-ATA HDD.

dpmssettimeouts
DPMSSetTimeouts(3) X FUNCTIONS DPMSSetTimeouts(3)
NAME
DPMSSetTimeouts - permits applications to set the timeout values used by the X server for DPMS timings
SYNOPSIS
cc [ flag ... ] file ... -lXext [ library ... ]
#include <X11/extensions/dpms.h>
Status DPMSSetTimeouts
(
Display *display,
CARD16 standby,
CARD16 suspend,
CARD16 off
);
ARGUMENTS
display
Specifies the connection to the X server
standby
Specifies the new standby timeout in seconds
suspend
Specifies the new suspend timeout in seconds
off Specifies the new off timeout in seconds
DESCRIPTION
The DPMSSetTimeouts function permits applications to set the timeout values used by the X server for Display Power Management Signaling
(DPMS) timings.
The value standby is the amount of inactivity time, in seconds, before standby mode is invoked. The actual effects of this mode are depen-
dent on the characteristics of the monitor and frame buffer card. Standby mode is implemented by shutting off the horizontal sync signal,
and pulsing the vertical sync signal. Standby mode provides the quickest monitor recovery time. Note also that many monitors implement
this mode identical to suspend mode. A value of zero disables the standby mode.
The value suspend is the amount of time of inactivity, in seconds, before the second level of power savings is invoked. Suspend mode's
physical and electrical characteristics are implementation defined. For DPMS compliant hardware, setting the suspend mode is implemented by
pulsing the horizontal sync signal and shutting off the vertical sync signal. In general, suspend mode recovery is considered to be slower
than standby mode, but faster than off mode. However it may vary from monitor to monitor. As noted above, many monitors implement this
mode identical to the standby mode. A value of zero disables this mode.
The value off is the amount of time of inactivity,in seconds, before the third and final level of power savings is invoked. Off mode's
physical and electrical characteristics are implementation defined. In DPMS compliant hardware, it is implemented by shutting off both hor-
izontal and vertical sync signals, resulting in powering down of the monitor. Recovery time is implementation dependent. Usually the
recovery time is very close to the power-up time of the monitor. A value of zero disables this mode.
Chronologically, standby mode occurs before or simultaneously with suspend mode, and suspend mode must occur before or simultaneously with
off mode. Therefore, non-zero mode timeout values must be greater than or equal to the timeout values of earlier modes. If inconsistent
values are supplied, a BadValue error will result.
RETURN VALUES
TRUE The DPMSSetTimeouts function returns TRUE when the function has succeeded.
ERRORS
BadValue An argument is out of range.
