unmirrorvg----reducevg----redev -dl就会去干净
移除硬盘的时候做unmirror，那是因为保证VG中每块PV的VGDA都正确，避免重启的时候出错。做完unmirror之后，VGDA信息会更新。
做unmirror,并不会修改vgda的内容，在把硬盘从vg中删除时，才会修改卷组描述区

用逻辑卷镜象即可.如建好VG及其LV后就执行:
extendvg datavg hdisk1
mirrorvg -m datavg hdisk1
如果是rootvg,在执行:
chvg -Qn rootvg
bosboot -a
bootlist -m normal hdisk0 hdisk1
shutdown -Fr

viola!

恢复镜象

hdisk0 是系统盘，hdisk1是其镜象盘。现在hdisk0坏掉了。
我用一下命令重建镜象
unmirrorvg rootvg hdisk0
reducevg rootvg hdisk0
rmdev -l hdisk0 -d
替换坏的磁盘驱动器，把驱动器重命名为 hdisk0
extendvg rootvg hdisk0
mirrorvg rootvg报如下的错。
# mirrorvg rootvg
0516-010 lquerylv: Volume group must be varied on; use varyonvg command.
0516-1200 mirrorvg: Failed to mirror the volume
lsvg -l rootvg
lsvg -p rootvg
# mirrorvg rootvg
# mirrorvg -c 2 rootvg

[转帖]rootvg 的镜象
Mirror


1.Write down on which disks you logical volumes reside.
#lspv -l hdisk0

2.Now mirror each logical volume as described in your student notebook.
do not syncchronize the logical volumes in this step.
#mirrorvg -s rootvg

3.Display information about your rootvf using lsvg rootvg
#lsvg rootvg

4. Now synchronize your rootvg.
#syncvg -v rootvg

5. Check by using lsvg rootvg that all partitions have been updated:
#lsvg rootvg

6.Update your boot logical volumes and your boot list
#bosboot -ad /dev/hdisk1
#bootlist -m normal hdisk0 hdisk1
