In case the 01 in the server's display (left bottom corner) changed to HMC you'd have to do a factory reset through the ASMI. However, I am unsure whether removing all service processor settings (that includes all partiton information) will result into an IVM (which basically is the first partition on such a system) after booting the IVM. So make sure that you have backup(s) of both the IVM installation (backupios) and the LPAR (mksysb). It would be great if you share the experience whether resetting the SP and booting the IVM suffices.
ASMI can be used by commandline
IBM Systems Information Center or by GUI
