节前巡检发现两台数据库服务器没有做根盘镜像，可能是上次恢复系统以后，把以前的镜像恢复没有了，决定当天在重起机器前做两台服务器的根盘镜像
操作步骤：
日终结帐完毕以后操作执行
1、把/dev/dsk/c1t0d0作为c0t0d0的镜像
2、检查/tmp/partitionfile文件，如果没有则创建一个分区列表文件，为后面的idisk作准备
szxsrv1#[/]vi /tmp/partitionfile
3
EFI 500MB
HPUX 100%
HPSP 400MB
3、Create the system, OS, and service partitions.
szxsrv1#[/]idisk -wf /tmp/partitionfile /dev/rdsk/c1t0d0
idisk version: 1.31

4、在新创建的efi分区里面写入HPUX文件夹，类似于pa机型作mkboot 写lif区
szxsrv1#[/]mkboot -e -l /dev/rdsk/c1t0d0
5、编辑一个auto文件，准备把它copy到efi分区里面去
szxsrv1#[/]echo "boot vmunix -lq" >/tmp/AUTO.lq
6、把刚刚编辑的auto.lq文件copy到c2t0d0s1(c2t0d0的efi分区)，放在/EFI/HPUX/AUTO,这一步对应pa机型的mkboot –a “hpux -lq”
szxsrv1#[/]efi_cp -d /dev/rdsk/c1t0d0s1 /tmp/AUTO.lq /EFI/HPUX/AUTO
szxsrv1#[/]efi_cp -d /dev/rdsk/c0t0d0s1 -u /EFI/HPUX/AUTO /tmp/AUTO.pri
szxsrv1#[/]efi_cp -d /dev/rdsk/c1t0d0s1 -u /EFI/HPUX/AUTO /tmp/AUTO.alt
7、把两块根盘的AUTO文件都copy出来，作个检查
szxsrv1#[/]cat /tmp/AUTO.pri
boot vmunix
szxsrv1#[/]cat /tmp/AUTO.alt
boot vmunix –lq
8、/dev/dsk/c1t0d0s2是真正的要放数据的部分，把它作成pv
szxsrv1#[/]pvcreate -fB /dev/rdsk/c1t0d0s2
9、＃把c1t0d0s2加入vg00
szxsrv1#[/]vgextend vg00 /dev/dsk/c1t0d0s2
10、编辑一个mirror脚本，里面内容就是lvextend -m 1 /dev/vg00/lvol1~8 /dev/dsk/c1t0d0s2
szxsrv1#[/]vi /tmp/mirror.sh
11、执行mirror脚本
szxsrv1#[/]sh /tmp/mirror.sh
12、把新硬盘加入到bootconf文件中，注意用s2的设备文件
l /dev/dsk/c0t0d0s2
l /dev/dsk/c1t0d0s2
13、检查
szxsrv1#[/]vgdisplay -v vg00|more
