When I've done this process, I've always had a few steps to it:-

Clean up anything left from last time, e.g. old files, filesystems or logical volumes
Run mkszfile to ensure that the filesystem sizes are recorded correctly
Run savevg excluding all the files to collect the information about all the non-rootvg volume groups, saving the detail somewhere within rootvg
Run mksysb writing to a file on disk in a specified area outside the rootvg with the -e flag to exclude files in /etc/exclude.rootvg
Run mkdvd specifying the mksysb file created in the previous step

It may not be perfect, but it works very well and I even managed to edit the data files used by savevg to specify non-mirrored logical volumes in case we recover to a server without sufficient disk space to have the mirrors.

Sadly I have now lost access to the AIX servers I have worked on so I cannot share it.

I hope that at least this process might help.

vgreduce

VGREDUCE(8)						      System Manager's Manual						       VGREDUCE(8)

NAME

       vgreduce - reduce a volume group

SYNOPSIS

       vgreduce  [-a|--all] [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [--removemissing] [-t|--test] [-v|--verbose] VolumeGroupName [Physi-
       calVolumePath...]

DESCRIPTION

       vgreduce allows you to remove one or more unused physical volumes from a volume group.

OPTIONS

       See lvm for common options.

       -a, --all
	      Removes all empty physical volumes if none are given on command line.

       --removemissing
	      Removes all missing physical volumes from the volume group, if there are no logical volumes allocated on those. This resumes  normal
	      operation of the volume group (new logical volumes may again be created, changed and so on).

	      If this is not possible (there are logical volumes referencing the missing physical volumes) and you cannot or do not want to remove
	      them manually, you can run this option with --force to have vgreduce remove any partial LVs.

	      Any logical volumes and dependent snapshots that were partly on the missing disks get removed completely. This includes those  parts
	      that lie on disks that are still present.

	      If your logical volumes spanned several disks including the ones that are lost, you might want to try to salvage data first by acti-
	      vating your logical volumes with --partial as described in lvm (8).
