请教多CPU问题(Help on multi-processor)

[weixin_38055275]

我有一台别人安装好的服务器，带2个CPU，但只有一个CPU是工作的，或者说，系统启动自检时显示有2个CPU，但启动后用psrinfo -v 或其它命令检查却只能看到一个CPU。请问如何才能使另一个CPU也工作？
I have a server already installed Solaris 7 SunOS 5.7 by somebody else. It has two CPUs, but only one CPU is working. How can I make both of them work? Please help me. Thank you very much.
