SDD SDDPCM MPIO lspath Jargon

Can anyone recommend me some reading material surrounding how AIX handles LUNs:
- with and without MPIO installed
- with and without SDD or SDDPCM installed
Where does lspath sit in all of this (MPIO layer?). Can a system be built with just MPIO software? Is MPIO software even needed?

I guess I am trying to conceptualize what is seen on a system before and after you install the above software.

XUninstallColormap()													      XUninstallColormap()

Name
  XUninstallColormap - uninstall a colormap; install default if not already installed.

Synopsis
  XUninstallColormap(display, colormap)
	Display *display;
	Colormap colormap;

Arguments
  display   Specifies a connection to an X server; returned from XOpenDisplay().

  colormap  Specifies the colormap to be uninstalled.

Description
  If colormap is an installed map for its screen, it is uninstalled.  If the screen's default colormap is not installed, it is installed.

  If  colormap	is an installed map, a ColormapNotify event is generated on every window having this colormap as an attribute.	If a colormap
  is installed as a result of the uninstall, a ColormapNotify event is generated on every window having that colormap as an attribute.

  At any time, there is a subset of the installed colormaps, viewed as an ordered list, called the required list.  The length of the required
  list	is  at most the min_maps specified for each screen in the Display structure.  When a colormap is installed with XInstallColormap() it
  is added to the head of the required list and the last colormap in the list is removed if necessary to keep  the  length  of	the  list  at
  min_maps.   When a colormap is uninstalled with XUninstallColormap() and it is in the required list, it is removed from the list.  No other
  actions by the server or the client change the required list.  It is important to realize that on all  but  high-performance	workstations,
  min_maps is likely to be one.

  For more information on installing and uninstalling colormaps, see Volume One, Chapter 7, Color.

Errors
  BadColor  Invalid colormap.
