# chhwres -r proc -m Managed-System -o r -p Lpar_name -procs 1

To move 1 dedicated cpu from lpar_a to lpar_b dynamically :

# chhwres -r proc -m Managed-System -o m -p Lpar_a_name -t Lpar_b_name -procs 1

To add 0.5 processing unit to an lpar dynamically :

# chhwres -r proc -m Managed-System -o a -p Lpar_name -procunits 0.5
