cpu:::mincpu:::min

• minimum number of CPUs assigned to the partition• number of bound CPUs

• •minimum number of CPUs assigned to the partition cannot change min while virtual partition is up

• number of CPUs assigned by hardware path is subset

of min

• cannot change min while virtual partition is up

cpu:hw_pathcpu:hw_path

• specify CPU by hardware path• specify CPU by hardware path

• •number of CPUs assigned by hardware path is subset

of min

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 setting

• on dual-core processor systems, hw_path refers to the

CPU cores (see ioscan(1M))

cpu::total

• total = (number of CPUs assigned by hw_path) +

(number of CPUs assigned by cell) + (number of CPUs

assigned by vPars Monitor)

NOTE: when the virtual partition is booted, one of the

CPUs from the operand list above becomes the boot

processor.

NOTE: from a user’s point of view, the same CPU could

be considered under more than one category. However,

the vPars Monitor will categorize and count a CPU only

once. Use vparstatus -v to see the CPU details.

cpu::total

• total = bound + unbound CPUs

max as in cpu:::min:max

• same meaning as in A.03.xx

max as in cpu:::min:max

• max is maximum number of CPUs that can be assigned

to the partition
