• total <= max

• when a virtual partition is down, the number of CPUs

assigned by hardware path must be less than or equal

to the pre-existing total

adding to or deleting from the total count of CPUs is

performed by any of the following:

adding to or deleting from the total count of CPUs

assigned to a virtual partition is performed by only

• modifying total directly (cpu::total)

• adding or deleting by hw_path (cpu:hw_path)

◦ if the virtual partition is up, total will be adjusted

automatically (unless the CPUs are already assigned

to the partition)

◦ if the virtual partition is down, the number of CPUs

assigned by hardware path must be less than or

equal to the pre-existing total

if this is the case, you should first modify total to

allow the additional CPU.

• adding or deleting by CLP

◦ total will be adjusted automatically

adding by num (-a cpu::num)

• deletion requires decreasing by num (-d cpu::num) or

by hw_path (-d cpu:hw_path)

adding by num (-a cpu::num)

• deletion requires decreasing by num (-d cpu::num)

adding by hw_path (-a cpu:hw_path)adding by hw_path (-a cpu:hw_path)

• deletion requires deleting by hw_path (-d cpu:hw_path)• deletion requires deleting by hw_path (-d cpu:hw_path)

• •this does not adjust total this does adjust total if the virtual partition is up

(unless the CPU is already assigned to the partition);

• this does not adjust min

otherwise, if the virtual partition is down, the number

of CPUs assigned by hardware path must be less than

or equal to the current total

• requires the partition to be down

• partition can be up or down
