HP-UX Virtual Partitions Administrator Guide (includes A.05.08) (5900-1312, March 2011)

NOTE: In a mixed HP-UX 11i v2/v3 vPars environment or a mixed HP-UX 11i v1/v2/v3 vPars
environment, dynamic memory migration is only supported on the vPars versions that support
dynamic memory migration. In other words, memory migration operations can be initiated only
from virtual partitions running vPars A.05.xx, and the virtual partition target for the memory migration
must be running vPars A.05.xx as well.
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
Table 5 CPU Syntax from A.03.xx to A.04.xx/A.05.xx
vPars A.04.xx/A.05.xx SyntaxvPars A.03.xx Syntax
cpu:::min
• minimum number of CPUs assigned to the partition
• cannot change min while virtual partition is up
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: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:hw_path
• specify CPU by hardware path
• number of CPUs assigned by hardware path is subset
of min
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
