HP-UX Virtual Partitions Administrator Guide (includes A.05.09) (5900-2188, March 2012)

“Commands: Displaying vPars Monitor and Resource Information
(vparstatus)” (page 135).
You can manage CPUs in multiple ways:
by min and max limits: See “CPU: Specifying Min and Max Limits” (page 187)
by total See “CPU: Adding and Deleting by Total” (page 187)
by cell local processor See “CPU: Adding or Deleting by CLP (Cell Local Processor)”
(page 189)
by hardware path See “CPU: Adding or Deleting by Hardware Path” (page 190)
CPU: Specifying Min and Max Limits
The syntax to specify min and max CPUs assigned to a virtual partition is:
-[a|m] cpu:::[min][:max]
where:
-a add (used with vparcreate or vparmodify)
-m modify (used with vparmodify)
min the minimum number of CPUs for the virtual partition to boot and the minimum number of
CPUs that must remain assigned to the partition
max the maximum number of CPUs that can be assigned to the virtual partition
NOTE: The virtual partition must be in the down state to set the min or max value.
The total count of CPUs in the virtual partition must always be greater than or equal to min and
less than or equal to max.
See “CPU: Notes on vPars Syntax, Rules, and Output” (page 190) regarding the new concepts and
count rules for min.
Examples
• To set the minimum number of CPUs to 2:
keira1# vparmodify -p keira2 -m cpu:::2
• To set the minimum number of CPUs to 2 and the maximum to 4:
keira1# vparmodify -p keira2 -m cpu:::2:4
CPU: Adding and Deleting 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.
