How to assign a physical processor to a logical processor
You can assign a physical processor to a logical processor, when the LPAR is
deactivated or activated in shared mode. If not setting the physical processor
number using this function, LPAR manager will assign a physical processor
when the LPAR is activated.
Place the cursor on the intersection between the LPAR column and the logical
processor number row, and press Enter to display the sub-screen. Enter the
physical processor number, and press Enter.
You cannot assign physical processors to logical processors if the guest NUMA
is enabled and the method for configuring logical processors for the guest
NUMA for the LPAR is physical NUMA node binding.
Note:
• The re-setting of this configuration is required when using this function
and changing the configuration that increases or decreases physical
processor (including the change of the hyper-thread setting enable/
disable). The condition and the reaction which require resetting of this
configuration are shown below.

Re-set and save the configuration on the Logical Processor
Configuration screen when the re-setting of physical
processor number to logical processor is necessary.
LPAR manager allocates the physical processor
automatically when you do not re-set.
• For an LPAR for which the method for configuring logical processors for
the guest NUMA is physical processor binding, when this configuration
method is changed to physical NUMA node binding, all configuration
information for the LPAR changes to "Auto".Afterwards, if you change the
method for configuring logical processors for the guest NUMA to physical
