AIX tools for SAP Administrators Set 3

savevg -v -n -9 / _rootvg.img rootvg
This can be used to build a NIM installable image to recover your systems

alternatively, the command line call for a mksysb to tape (to include map
and exclude files) is /usr/bin/mksysb '-m' '-e' '-i' /dev/rmt0

Finding which lpp contains a file:
lslpp -w /usr/sbin/umount
