Cpu-Core: Adding And Deleting By Total - HP Integrity Superdome 2 16-socket Administrator's Manual

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.
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

NOTE: A vPar can be modified only when it is in the "Down" state.
The syntax to add or delete CPUs is:
-a, -d, -m cpu::num
where:
specifies adding, deleting, or modifying the total count of CPUs
-a, -d, -m
specifies the number of CPUs
cpu::num
NOTE:
-d cpu::num syntax (deletion by total), or
-d socket:{socket_path}:cpu::num syntax (deletion by total in a specific socket), or
-d cpu:hw_path syntax (deletion by resource path)
To add or delete CPUs, a virtual partition must be down.
Deletion by total (cpu::num) is required when cores that were assigned by total are to be deleted.
Deletion by path is required when cores added by path are to be deleted.
The total increases or decreases by num when the -a or -d options are used and is set to num
when the -m option is used.
vparcreate
With the vparcreate command, use the -a option and specify as num the number of CPUs
allocated to the virtual partition.
If no cpu syntax is given on the vparcreate command line, the default value for total cpu is 0.
