You should be able to delete all those from the ODM .. have u got an
AIX support contract ? if so then give them a call and they will give you the commands .. but in summary u need to grab the lpp_id for each one from lpp ODM class, then delete anything relating to them from lpp, product, inventory and history ODM classes in both /etc/objrepos and /usr/lib/objrepos
make sure you take a backup of both of those dirs before you start and if u screw up, then you can just restore them.
