Transitioning from vPars A.03.xx to vPars A.04.xx/A.05.xx
(CPU Syntax and Rules)
The values in a vPars database that were created using vPars A.03.xx and ported to vPars A.04.xx will have
the following A.04.xx meanings for those values; likewise, using vPars A.03.xx syntax on a vPars A.04.xx
system has the following A.04.xx meanings.
This table summarizes the A.04.xx and A.05.xx CPU syntax and rules

cpu:::
min
• number of bound CPUs
• minimum number of CPUs assigned to the
partition
• number of CPUs assigned by hardware path is
subset of
min
• cannot change
min
while virtual partition is up
cpu:::
min
• minimum number of CPUs assigned to the
partition
• cannot change
min
while virtual partition is up
cpu:
hw_path
• specify CPU by hardware path
• number of CPUs assigned by hardware path is
subset of
min
cpu:
hw_path
• specify CPU by hardware path
• 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 = bound + unbound CPUs
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.
