CPU
CPU migration refers to adding CPUs to and deleting CPUs from a virtual partition. Dynamic CPU
migration refers to migrating CPUs while the target virtual partition is running. vPars allows the
assignment of most CPUs while the virtual partitions are running.
For vPars A.04 and later, the two types of CPUs are Boot Processor and dynamic CPUs. This discussion
begins at “CPU: Boot Processor and Dynamic CPU Definitions” on page 180. The bound and unbound CPU
types in vPars A.03 and earlier no longer apply.
For additional information on using iCAP (formerly known as iCOD), including temporary-iCAP processors
with vPars, see “CPU: Using iCAP (Instant Capacity on Demand) with vPars (vPars A.04 and iCAP B.07)” on
page 188.
NOTE Using vPars A.03.xx and earlier syntax on a vPars A.04.xx system
Although not recommended under most circumstances, you can still use the vPars A.03.xx
CPU syntax on vPars A.04.xx systems. However, the concepts and rules of boot processors and
dynamic CPUs in A.04.xx will apply because the concepts and rules of bound and unbound
CPUs in A.03.xx no longer apply.
For more information, see “CPU: Syntax, Rules, and Notes” on page 186.
