1、檢視vg00：
vgdisplay -v /dev/vg00 ;
VG Name /dev/vg00
VG Write Access read/write
VG Status available
PE Size (Mbytes) 32
Total PE 4347
Alloc PE 1134
Free PE 3213
--- Logical volumes ---
LV Name /dev/vg00/lvol1
LV Name /dev/vg00/lvol2
LV Name /dev/vg00/lvol3
LV Status available/syncd
LV Name /dev/vg00/lvol4
LV Name /dev/vg00/lvol5
LV Name /dev/vg00/lvol6
LV Name /dev/vg00/lvol7
LV Name /dev/vg00/lvol8
--- Physical volumes ---
PV Name /dev/disk/disk3_p2
2、檢視磁盤：
# ioscan -m lun | grep disk
disk 3 64000/0xfa00/0x1 esdisk CLAIMED DEVICE online HP 146 GST3146707LC
/dev/disk/disk3 /dev/disk/disk3_p2（已用） /dev/rdisk/disk3 /dev/rdisk/disk3_p2
/dev/disk/disk3_p1 /dev/disk/disk3_p3 /dev/rdisk/disk3_p1 /dev/rdisk/disk3_p3
disk 5 64000/0xfa00/0x3 esdisk CLAIMED DEVICE online HP 146 GST3146707LC
/dev/disk/disk5 /dev/rdisk/disk5
即：
根盤是：/dev/rdisk/disk3
鏡像盤是：/dev/rdisk/disk5
即我安裝OS是，隻用了/dev/disk/disk3，沒有使用/dev/disk/disk5。

5、編寫磁盤的table檔案，并導入到mirror盤：
# mkdir /tmp/mirror/
# vi /tmp/mirror/table 輸入以下内容：
3
EFI 500MB
HPUX 100%
HPSP 400MB
6、#idisk -wf /tmp/mirror/table /dev/rdisk/disk5
idisk version: 1.44

8 、安裝分好區的裝置檔案；
# insf -eCdisk
将新磁盤制作成引導磁盤，需要注意的是要使用字元裝置：
# mkboot -e -l /dev/rdisk/disk5
9、修改兩塊磁盤的引導模式：
（-lq 不進行quorum 檢查，當一個VG 隻有少于等于50%的硬碟可以正常通路時，預設情況下就不能被激活，加這個參數以後就可以強行激活，在配置了根盤鏡像的情況下經常會用到這個參數）。
# mkboot -a "boot vmunix -lq" /dev/rdisk/disk3; 根盤。
# mkboot -a "boot vmunix -lq" /dev/rdisk/disk5; 鏡像盤。
# efi_cp -d /dev/rdisk/disk3_p1 -u /efi/hpux/auto /dev/tty; --檢視是否修改成功；
# efi_cp -d /dev/rdisk/disk5_p1 -u /efi/hpux/auto /dev/tty; --檢視是否修改成功；
10、 将新盤（鏡像盤）的p2分區格式化成PV：
# pvcreate -fB /dev/rdisk/disk5_p2;
Physical volume "/dev/rdisk/disk5_p2" has been successfully created.
11、 将新盤的p2分區加入到VG00中：
# vgextend vg00 /dev/disk/disk5_p2 ;
12 、鏡像VG00中的所有LV；
# for lv in /dev/vg00/lvol*
> do
> lvextend -m 1 $lv /dev/disk/disk5_p2;
> done
注意：這裡 > 是指令符合，回車後自動産生的。
13、恢複所有的BDRA資訊：
# lvlnboot -R
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf
14、 檢視鏡像情況：
# lvlnboot -v
15、修改引導配置檔案：
# vi /stand/bootconf
l /dev/disk/disk3_p2 字母“l”（L 的小寫形式）代表 LVM 。
2 /dev/disk/disk5_p2
16、設定系統引導的裝置及順序：
# ioscan -fnCdisk

17、重新啟動系統，驗證鏡像是否成功，檢視是否從設定的裝置磁盤引導：
# shutdown -ry 0 重新開機時選擇所要啟動的路徑。
# grep "Boot" /var/adm/syslog/syslog.log
