• Because you can dynamically migrate unbound CPUs, you can
migrate an unbound CPU from one partition to another while both
partitions are running. For example, if the partition winona1 has two
bound CPUs and the partition winona2 has two bound and two
unbound CPUs, you can migrate an unbound CPU from winona2 to
winona1 using the following:
winona1# vparmodify -p winona2 -d cpu::1
winona1# vparmodify -p winona1 -a cpu::1
NOTE For more information on CPUs, see the following:
• For information on bound and unbound CPUs, see “Bound and
Unbound CPUs” on page 48.
If you do not know which CPUs are bound CPUs and which are
unbound CPUs, use the vparstatus command. See “Obtaining
Monitor and Hardware Resource Information” on page 129 and the
vparstatus (1M) manpage.
• For issues with the vparmodify command, see the vparmodify (1M)
manpage.
For the required partition states, see the vparresources (5)
manpages.
