hp-ux 11.31 VG00 mirror
1、 查看磁盘设备名、硬件路径、VG00中的当前磁盘；
# vgdisplay -v vg00;
--- Physical volumes ---
PV Name /dev/disk/disk3_p2
PV Status available
Total PE 4347
Free PE 367
Autoswitch On
Proactive Polling On
# ioscan -kfnCdisk

2、 编写磁盘的table文件并导入到mirror盘；
#vi /tmp/mirror/table
3
EFI 500MB
HPUX 100%
HPSP 400MB
# idisk -wf /tmp/mirror/table /dev/rdisk/disk5;
# idisk /dev/rdisk/disk5;--查看是否导入成功；
3、 安装分好区的设备文件；
# insf -eCdisk
4、 将新磁盘制作成引导磁盘，需要注意的是要使用字符设备；
# mkboot -e -l /dev/rdisk/disk5;
# efi_ls -d /dev/rdisk/disk5 /efi/hpux;--查看上条命令是否成功；
5、 修改两块磁盘的引导模式（-lq 不进行quorum 检查。当一个VG 只有少于等于50%的硬盘可以正常访问时，默认情况下就不能被激活。加这个参数以后就可以强行激活，在配置了根盘镜像的情况下经常会用到这个参数)；
# mkboot -a "boot vmunix -lq" /dev/rdisk/disk3;
# mkboot -a "boot vmunix -lq" /dev/rdisk/disk5;
# efi_cp -d /dev/rdisk/disk3_p1 -u /efi/hpux/auto /dev/tty;--查看是否修改成功；
# efi_cp -d /dev/rdisk/disk5_p1 -u /efi/hpux/auto /dev/tty;--查看是否修改成功；
6、 将新盘的p2分区格式化成PV；
# pvcreate -fB /dev/rdisk/disk5_p2;
Physical volume "/dev/rdisk/disk5_p2" has been successfully created.
7、 将新盘的p2分区加入到VG00中；
# vgextend vg00 /dev/disk/disk5_p2;
Volume group "vg00" has been successfully extended.
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf
8、 镜像VG00中的所有LV；
# for lv in /dev/vg00/lvol*
> do
> lvextend -m 1 $lv /dev/disk/disk5_p2;
> done
9、 恢复所有的BDRA信息；
# lvlnboot -R
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf
# lvlnboot -v;--查看镜像情况；
Boot Definitions for Volume Group /dev/vg00:
Physical Volumes belonging in Root Volume Group:
/dev/disk/disk3_p2 -- Boot Disk
/dev/disk/disk5_p2 -- Boot Disk
Boot: lvol1 on: /dev/disk/disk3_p2
/dev/disk/disk5_p2
Root: lvol3 on: /dev/disk/disk3_p2
/dev/disk/disk5_p2
Swap: lvol2 on: /dev/disk/disk3_p2
/dev/disk/disk5_p2
Dump: lvol2 on: /dev/disk/disk3_p2, 0
10、 修改引导配置文件；
vi /stand/bootconf
l /dev/disk/disk3_p2
2 /dev/disk/disk5_p2
11、 设备系统引导的设备及顺序；
# ioscan -fnCdisk

# setboot -p 4/0/8/1/0.0.0
# setboot -h 4/0/1/1/0.0.0
注：-p表示主引导设备；-h表示备用引导设备；
12、 重新启动系统，查看是否从设备的磁盘引导；
# grep “Boot device’s HP-UX HW path” /var/adm/syslog/syslog.log
