HP Superdome 2 Partitioning Administrator Guide (5900-2540, December 2012)

NOTE: On an HP Integrity Superdome 2 system, a vPar is created with zero CPUs by default.
Therefore, the default cpu:::[min] value is zero. The default cpu::::[max] value is the total number
of CPUs in the nPartition.
The virtual partition must be in the "Down" state to set the minimum or maximum value. Now the
firmware allows you to create vPars irrespective of the min or max count, but upon poweron, it
fails with the appropriate error message if it is not in the range of minimum or maximum count.
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.
Examples
To set the minimum number of CPUs to 2:
vparmodify -N <nPar name> -m cpu:::2
To set the minimum number of CPUs to 2 and the maximum to 4:
vparmodify -N <nPar name> -m cpu:::2:4
CPU-core: Adding and Deleting by Total
The syntax to add or delete CPUs is:
-a, -d, -m cpu::num
where:
-a, -d, -m specifies adding, deleting, or modifying the total count of CPUs
cpu::num specifies the number of CPUs
