Deactivating a LPAR is equivalent to turning off the

power supply of the LPAR, so due care should be taken
when performing this operation. In particular, the hard
disk might get damaged if you perform this operation
while data is being accessed on the LPAR such as
booting the guest OS. We strongly recommend that you
shutdown the guest operating system before
deactivating it.
If LP auto shutdown is set, the LPAR manager system

will automatically shutdown once all the LPARs have
been deactivated. See Options
shutdown.
