大侠救命!red hat6.2 hp服务器出错了!

hp服务器(作为公司网站及邮件服务器),操作系统linux red hat 6.2
今天中午我们公司的HP服务器无法登录,PING不通,重启,进入login#:
提示符,输入正确用户名和密码,无法登录进去,重新退回login#提示符下,什么提示也没有。
后来在重启时按“I”进入“I”模式(press "I" to enter interactive startup)出现如下错误:
 Start service network (Y)es (N) (C) continue ?(Y)
/etc/rc.d/rc3.d/S10network :/etc/init.d/function/=No such file or directory
/etc/rc.d/rc3.d/s10... action :command not found
/etc/rc.d/rc3.d/s10... action :command not found

Start service apmd (Y)es ....

r execute as root
R remove PID forever
U uninstall adore

v make PID visible

请大侠HELP!  

      
能进单用户模式吗?

或者用光盘引导.

先进去看看再说
