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.
