"psadm -f cpu-id"
What would happen if something is running on that CPU?

具体也没有去试,
参考一下吧.
prsradm -f procid 将处理器procid设为离线.
-n 让指定处理器在线.
-a 作用于所有处理器.
-v 对每次操作尝试的结果显示一条信息.
只有超级用户和系统管理员才能执行这条命令,
如果有LWP被绑定在某处理器上,那么该处理器不能设为离线.

好象老外都使用psrset命令吧

我感觉这些命令，大家根本用不上的，它好像是主机内含有多块系统板时，才会用到的。

1、psradm - change processor operational status
The psradm utility changes the operational status of pro-
cessors. The legal states for the processor are on-line,
off-line, and no-intr.
An on-line processor processes LWPs (lightweight processes)
and may be interrupted by I/O devices in the system.
An off-line processor does not process any LWPs. Usually, an
off-line processor is not interruptible by I/O devices in
the system. On some processors or under certain conditions,
it may not be possible to disable interrupts for an off-line
processor. Thus, the actual effect of being off-line may
vary from machine to machine.
A no-intr processor processes LWPs but is not interruptible
by I/O devices.
-i Set the specified processors no-intr.
-n Bring the specified processors on-line.
-v Output a message giving the results of each attempted
operation.
