AIX 第五天偶记

shutdown -Fr 关机
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

SUMA打补丁是IBM的扯淡行为

AIX 6.1 光盘DVD2张，CD8张

systemdirector不支持win7

./lsr 单独安装。查机器配置

lsof /doc 查看有谁在用什么

/etc/rc.dt 启动aix x-window

在smit中按F4中才mount光驱，不用就unmount

@表示已经安装
@@表示是RPM格式的安装

/mnt表示
mount -o ro -v cdrfs /dev/cd0 /mnt
ummont /mnt

用smit来mount光驱比较好
mount /cdrom

不要自动mountCDROM

install software 只列出可以被安装的，如其他语言文件不列出
install and update from all acvailable software 列出所有的


但发现文件大小为0的时候
inutoc .
可以重新查看

geninstall
installp

打补丁instfix -k IY58143 -d /dev/cd0

instfix -i | grep ML
显示文件集装齐么有

instfix -i | grep SP
现在用这个

oslevel -sl 7100-00-03-1115 列出没有到这个级别的文件集

装半截的需要用installp -c清理一下

lslpp -w /usr/sbin/xinetd

LVM可以跨盘，可以动态增加，能够镜像，不需要关机停应用

LVM信息放在ODM和硬盘头部，也就是VGDA

dump device就是裸设备

卷组尺寸=PP数*PV数 一个卷组的PV值是固定的，PV不可改，

一般情况下：
PP＝LP
一个或多个LP构成LV
PV可划分为一个或多个LV
VG由一个或多个PV组成

1个VG内的1个PV的VGDA有2个，
1个VG内的2个PV的一个PV有2个VGDA，1个PV有1个VGDA
1个VG内的4个PV的每个PV有1个VGDA
