CPU: Adding or Deleting by CLP (Cell Local Processor)
Similar to CLM (cell local memory), CLP (cell local processor) refers to CPUs on a specific cell.
The syntax to specify CLP is:
-[a|d|m] cell:cell_ID:cpu::num
where:
a
add
d
delete
m
modify
cell_ID
the cell ID
num
the number of CPUs from the cell to be added to or deleted from the virtual partition.
Note that the num CPUs need to be available on the cell as well as the system before
they can be added. To see whether they are available or already allocated, use the
vparstatus command.
NOTE: The virtual partition can be either up or down when using the CLP syntax
(cell_ID:cpu::num).
CPUs that are added using the CLP syntax can be deleted only by using either:
• CLP syntax, or
• cpu:hw_path syntax (deletion by hardware path)
Adding or deleting CPUs by CLP changes total accordingly, regardless of whether the virtual
partition is up or down.
Examples
• To create a virtual partition using 2 CPUs from cell 6:
keira1# vparcreate -p keira2 -a cell:6:cpu::2 ...
• To increase the number of CPUs by 2 using the CPUs of cell 6:
keira1# vparmodify -p keira2 -a cell:6:cpu::2
To decrease the number of CPUs by 2 using the CPUs of cell 6:
keira1# vparmodify -p keira2 -d cell:6:cpu::2
CPU: Adding or Deleting by Hardware Path
The syntax for specifying by hardware path is:
-[a|d] cpu:hw_path
where:
a
add
d
delete
hw_path the hw_path (you can find the hardware path using ioscan or vparstatus -v)
