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.

DH_MISSING(1)							     Debhelper							     DH_MISSING(1)

dh_missing - check for missing files SYNOPSIS
dh_missing [-Xitem] [--sourcedir=dir] [debhelperoptions] DESCRIPTION
dh_missing compares the list of installed files with the files in the source directory. If any of the files (and symlinks) in the source directory were not installed to somewhere, it will warn on stderr about that (--list-missing) or fail (--fail-missing). Please note that without either of these options, dh_missing will silently do nothing. This may be useful if you have a large package and want to make sure that you don't miss installing newly added files in new upstream releases. Remember to test different kinds of builds (dpkg-buildpackage -A/-B/...) as you may experience varying results when only a subset of the packages are built. FILES
debian/not-installed List the files that are deliberately not installed in any binary package. Paths listed in this file are ignored by dh_missing. However, it is not a method to exclude files from being installed by any of the debhelper tool. If you want a tool to not install a given file, please use its --exclude option (where available). dh_missing will expand wildcards in this file (since debhelper 11.1). Wildcards without matches will be ignored. OPTIONS
--list-missing Warn on stderr about source files not installed to somewhere. Note that files that are excluded from being moved via the -X option are not warned about. This is the default in compat 12 and later. --fail-missing This option is like --list-missing, except if a file was missed, it will not only list the missing files, but also fail with a nonzero exit code. SEE ALSO
debhelper(7) This program is a part of debhelper. AUTHOR
