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 .
Please see “CPU: Notes on vPars Syntax, Rules, and Output” on page 223 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
