CPU: Adding or Deleting by CLP (Cell Local Processor)
(vPars A.04)
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] cell:cell_ID:cpu::num
where
a is adding
d is deleting
cell_ID is the cell ID
num is 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 the
• 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
