Beginning with vPars A.04.01, the restrictions
of bound CPUs have been removed as well as the terms bound and unbound.
Now, there are two types of CPUs: boot processors and dynamic CPUs.
The Boot Processor is the CPU on which the OS kernel of the virtual partition was booted.
There is one boot processor per virtual partition. On booting of a
virtual partition, the vPars Monitor determines which CPU becomes
the boot processor. Note that the specific CPU chosen as the boot
processor may differ across virtual partition reboots.
Dynamic CPUs are
all the other CPUs, because all CPUs, except the boot processor of
each virtual partition, can be dynamically migrated. You can find
which CPU is the boot processor by using the vparstatus command; see “Commands: Displaying vPars Monitor and Resource Information
(vparstatus)”.
Note that you can only add CPUs that are available.
If you are using iCAP (formerly known as iCOD), the CPUs must be active
and authorized by iCAP before you can add it to a virtual partition.
In A.04.xx, all CPUs can process I/O interrupts.
See “Managing I/O Interrupts”.
