Comparing A.03 and A.04 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 also summarizes the A.04.xx syntax and rules
Table 6-1 CPU Syntax from A.03 to A.04
vPars A.03 Syntax => vPars A.04 Syntax
cpu:::min
• number of bound CPUs
• minimum number of CPUs assigned to
the partition.
• 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
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
max as in cpu:::min:max
• max is maximum number of CPUs that
can be assigned to the virtual partition
max as in cpu:::min:max
• same meaning as in A.03
