请问solaris8下怎样offline 一个cpu，然后又怎么online回去？
需要重启机器吗？

| psradm -f cpu-id |

| "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. |
