(10) How to change the service ratio allocation of processor shared between LPARS
Open the Logical Partition Configuration screen. 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 subscreen 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.
Set "the number of processors assigned to an LPAR multiplied by 250 ms" or
greater as a service ratio. If not, processing performance might slow down under
heavy load.
(11) How to change the memory size allocated to an LPAR
Open the Logical Partition Configuration screen. Move the cursor over the Mem
column of the LPAR whose memory size you want to change, and press Enter. This
will open a subscreen where you can enter the memory size. Adjust the memory
size with the arrow keys ([↑], [→], [↓] or [←]), and press Enter.
The number of memory capacity can be changed only when the relevant LPAR is
inactive.
Memory area, isolated due to memory failure detected, cannot
be assigned to an LPAR.
With high-performance server blades with LPAR manager
firmware version 78-3X, up to 1044480 MB memory can be
assigned to LPARs.
(12) How to change the number of memory node to assign to an LPAR
LPAR manager firmware version 59-2X/79-2X or later
Place the cursor on the MN column of an LPAR line and press Enter to open a
subscreen. Set A or a node number and press Enter.
Assuming an LPAR with memory node assigned and that with
memory node not assigned are included in an environment,
the LPAR with memory node assigned might fail to be
activated when activation is executed from the LPAR with
memory node not assigned. Thus, make sure to assign
memory node to all LPARs when assigning memory node to
even one LPAR. If creating a mixed configuration, make sure
to activate the LPAR with memory node assigned first, and to
activate the LPAR with memory node not assigned last.
(13) How to find the node number of processor and memory assigned to an LPAR
LPAR manager firmware version 59-2X/79-2X or later
You can find the processor and memory assigned to an LPAR that belongs to the
same node by checking PN: Processor Node, and MN: Memory Node on the
screen. When the same number: node number is displayed as the value of PN and
MN, the physical processor and physical memory assigned to the LPAR belong to
the same node.
