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

dynamic CPU migration
• all CPUs except the boot processor can be migrated
while a virtual partition is up
dynamic CPU migration
• only unbound CPUs can be migrated while a virtual
partition is up
count rules
• min <= 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

details
• 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

• number of CPUs assigned by hw_path <= min
• min<= total<= max
