HP-UX vPars and Integrity VM V6.3 Administrator Guide

where:
-a add (used with vparcreate or vparmodify).
-m modify (used with vparmodify).
min the minimum number of CPUs that must remain assigned to the partition.
max the maximum number of CPUs that can be assigned to the vPar.
NOTE: The vPar can be either UP or DOWN when setting the min or max value. Hence, a reboot
is not necessary when you modify the min and max value. When the partition is UP, the CPU count
can only be adjusted if the HP-UX OS on the vPar is running. CPU counts cannot be adjusted while
the vPar is in EFI state.
Example 16 Setting the minimum number of CPUs to 2
hostmachine# vparmodify -p machinename -m cpu:::2
Example 17 Setting the minimum number of CPUs to 2 and the maximum to 4
hostmachine# vparmodify -p machinename -m cpu:::2:4
10.1.2 Adding and deleting CPUs or cores by total
The basic syntax for adding and deleting CPUs is:
-[a|d|m] cpu::num
where:
-a|d|m specifies adding, deleting, or modifying the total count of CPUs.
num specifies the number of CPUs.
NOTE: The vPar can be either UP or DOWN when using the cpu::num syntax.
When the vPar is active, CPUs that were added using the cpu::num syntax can be deleted only
by using cpu::num syntax.
The total increases or decreases by num when the -a or -d option is used, and is set to num when
the -m option is used.
vPar does not support assignment of resources based on hardware path or socket locality.
Example 18 Add two CPUs or cores to a vPar
hostmachine# vparmodify -p machinename -a cpu::2
Example 19 Delete two CPUs or cores from a vPar
hostmachine# vparmodify -p machinename -d cpu::2
Example 20 Modify the total count of CPUs or cores of a vPar
hostmachine# vparmodify -p machinename -m cpu::4
10.1.3 Specifying base and floating memory
Starting V6.2, vPar memory is of two types:
