How to change a processor group number of an LPAR
Place the cursor on the intersection between the LPAR line to change the
processor group number and 'Grp' column, and press [Enter] to display a
sub-screen. Select a processor group number of the LPAR to configure, and
press [Enter] on the sub-screen.
You can change a processor group number, when the LPAR is deactivated or
activated in shared mode. If one of the following conditions is met, however,
an error message will appear to terminate the screen.
– The scheduling mode of an LPAR is 'Shared' and the LPAR is activated.
– No physical processor in shared mode exists in the group whose number is
to be changed.
For adding and changing the processor group number, see
processor group on page 7-34

Note:
• When LPAR migration is completed, the processor group number is the
default value, processor group 0.
How to change the service ratio allocation of processor shared
between LPARS
Move the cursor over the 'Srv' column of the LPAR whose processor service
ratio you want to change, and press [Enter]. This will open a sub-screen
where you can enter a service ratio value. Enter the desired service ratio
(between 1 and 999), and press [Enter].
Shared processor mode must be configured to change this setting.
Note:
• Set the service ratio so that the service time becomes the number of
processors assigned to an LPAR multiplied by 250ms. If not, processing
performance may slow down under heavy load.
How to change the memory size allocated to an LPAR
Move the cursor over the 'Mem' column of the LPAR whose memory size you
want to change, and press [Enter].
This will open a sub-screen where you can enter the memory size. Adjust the
memory size with the arrow keys, and press [Enter].
For an LPAR for which the guest NUMA is enabled, specify the memory size
for each node.
Move the cursor over the "Mem" column of the "LPAR" row whose memory
size you want to change, and press [Enter]. On the displayed sub-screen,
move the cursor over the "Mem Size" column of the "Node" row, and press
