Memory is split probably due to adding and removing memory from virtual machine, to other virtual machines etc.
They system/hypervisor will try it's best to satisfy your additional memory request with continuous memory space, if possible, if not it will give you free memory present on the system.

PA is physical addresss, as for RA i'm not sure Linux

The LDOM itself will see the cumulative value of those present, 118 GB.

You can check that from the ldom itself via :
echo "::memstat" | mdb -k

Hope that helps
