HP-UX Virtual Partitions Administrator Guide (includes A.05.08) (5900-1312, March 2011)

keira1# vparmodify -p keira2 -m cpu::2
• If you would like to add 1 CPU to an existing partition, regardless of its current CPU count,
you can add 1 CPU by using the -a option and setting num to 1:
keira1# vparmodify -p keira2 -a cpu::1
To remove the added CPU from the partition, use the -d option and set num to 1:
keira1# vparmodify -p keira2 -d cpu::1
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: CPU deletion fails when deletion by total and by CLP are given in the same vparmodify
command.
In this situation, the CPU deletion by total fails with the error message “vPar does not own enough
Monitor-assigned CPUs to satisfy the request” although there are enough monitor-assigned CPUs.
Instead, issue separate vparmodify commands to delete by total and delete by CLP.
For example instead of issuing the following command:
# vparmodify -p vpar1 -d cell:3:cpu::2 -d cpu::1
Issue two separate commands to delete by CLP and then by total:
# vparmodify -p vpar1 -d cell:3:cpu::2
# vparmodify -p vpar1 -d cpu::1
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
