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

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
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 is adding
-d is deleting
hw_path is the hw_path (you can find the hardware path using ioscan or vparstatus
-v)
