Example • To create a virtual partition with 3 CPUs, set num to 3: vparcreate -N nParID -p vParID -a cpu::3 or vparcreate -p nparID:vParID -a cpu::3 vparmodify With the vparmodify command, you can use: • -a option to add num CPUs to the virtual partition, • -d option to delete num CPUs from the virtual partition, • -m option to modify (set) to num the number of CPUs assigned to the partition. Examples • If an existing partition has 2 CPUs and you want to set the number of CPUs to 3, modify the number of CPUs assigned to the partition using the -m option and set num to 3: vparmodify -N nPar0001 -p vPar0001 -m cpu::3 To set the number of CPUs back to two, use the -m option and set num to 2: vparmodify -N nPar0001 -p vPar0001 -m cpu::2 • If you want to add 1 CPU-core to an existing partition, regardless of its current CPU-core count, you can add 1 CPU-core by using the -a option and setting num to 1: vparmodify -N nPar0001 -p vPar0001 -a cpu::1 To remove the added CPU-core from the partition, use the -d option and set num to 1: vparmodify -N nPar0001 -p vPar0001 -d cpu::1 CPU-core: Adding or Deleting by Socket Local Processor (SLP) SLP is similar to the socket local memory (SLM), and refers to CPUs in a specific socket on a specific blade.

Example
•
To create a virtual partition with 3 CPUs, set
num
to 3:
vparcreate -N nParID -p vParID -a cpu::3
or
vparcreate -p nparID:vParID -a cpu::3
vparmodify
With the
vparmodify
command, you can use:
•
-a
option to add
num
CPUs to the virtual partition,
•
-d
option to delete
num
CPUs from the virtual partition,
•
-m
option to modify (set) to
num
the number of CPUs assigned to the partition.
Examples
•
If an existing partition has 2 CPUs and you want to set the number of CPUs to 3, modify the
number of CPUs assigned to the partition using the
-m
option and set
num
to 3:
vparmodify -N nPar0001 -p vPar0001 -m cpu::3
To set the number of CPUs back to two, use the
-m
option and set
num
to 2:
vparmodify -N nPar0001 -p vPar0001 -m cpu::2
•
If you want to add 1 CPU—core to an existing partition, regardless of its current CPU—core
count, you can add 1 CPU—core by using the
-a
option and setting
num
to 1:
vparmodify -N nPar0001 -p vPar0001 -a cpu::1
To remove the added CPU—core from the partition, use the
-d
option and set
num
to 1:
vparmodify -N nPar0001 -p vPar0001 -d cpu::1
CPU-core: Adding or Deleting by Socket Local Processor (SLP)
SLP is similar to the socket local memory (SLM), and refers to CPUs in a specific socket on a specific
blade. The syntax to specify SLP is:
-a, -d socket:
socket_ID
:cpu::
num
where:
-a
is adding
-d
is deleting
socket_ID
is the path
(enclosure#/blade#/socket#)
num
is the number of CPU-cores from the socket to be added to or deleted from the
virtual partition. Note that the
num
CPU-cores must be available in the socket and
in the nPartition before they can be added. To verify the allocation of num
CPU-cores, use the
vparstatus -A
command when the nPartition is booted in
vPar mode.
