shutdown 关机，但要一分钟
halt -q 直接关机相当于直接掉电让HACMP接管
不推荐使用reboot关机
shutdown +4 阿斯顿阿斯顿阿斯的 四分钟后广播出去广播可以用
ctrl+c可以中止，也可以kill掉此进程
shutdown -m 切换到当用户模式，对于init -m来说，比init好用，init常常无效
shutdown -t mmddhhyy 指定一个时间重新开机
shutdown -u 对于升级微码有用
一般指定一个用户到service分区的组来升级微码
/etc/rc.shutdown 中写一个关机之前关闭数据库
Multiboot startup <off> 让startup启动的时候给出一个列表，和windows不同，如果不选择引导方式则会一直等待，不会选择一个默认项timeout。
有多个硬盘的情况下，只显示有MBR的硬盘。
SANBOOT不能安装操作系统
安装iscsi软件方式共享方式，由于是软件方式所以不支持引导，性能很差
不要选择默认安装方式，因为默认安装不同的机器，不同的安装次数，不同的配置默认的情况都不一样。
使用迁移方式进行安装花的时间比新安装要慢得多。要等近1个小时。遇到钉子户，硬盘灯不转，光盘不转，机器像死机状态。
老版本没有，新版本有的情况：安装缺省安装选项进行安装。
建议买硬盘至少3块而且最好大小不一样。这样实验的环境更丰富些。
建议不要选择中文，选择英文，将中文作为第二语言。
installs all devices 装完所有的驱动这样就是和将硬盘带到其他的小机上安装，也可以备份出来。
如果光盘坏了怎么办，它会继续读盘，那么就要把光盘推出，系统安装就自动跳开。
date命令执行后以DT结尾即是夏令时
