先unmirrorvg rootvg
再reducevg root hdiskx
rmdev -l /dev/hdiskx -d

接着chdev -f /dev/hdiskx
再将新硬盘加入到rootvg, extendvg rootvg hdiskx
再作mirror,  mirror -c 2 rootvg

目前，我已经无法unmirrorvg了，怎么办
谢谢

逐个 rmlvcopy  lvname  hdiskX
reducevg vgname hdiskX

如果 hdisk 已经被 rmdev 删除了，则
lquery -p hdiskX -At   得到 pvid
然后reducevg vgname pvid

why not you can not run #unmirrorvg rootvg 00563b8d1570663a,

hehe

why you want to do unmirrorvg ? you do not need to use the unmirrorvg command, then you can fix your issue.

rmlvcopy is a better command for you, I think.

I have already run rmlvcopy command.But the error was same as the unmirrorvg command.

lquery怎么没有这个命令，是AIX5L的命令吗？
我没有看到这个命令啊

use redefine rootvg command first, then use lspv to see if the pv is in the vg,  then use rmlvcopy

你的意思是说用
# redefinevg -d hdisk0 rootvg
也就是说，通过这个命令可以将mirror的那块盘从VG中剃除了是吗？
然后再rmlvcopy就可将单个LV移除mirror是吗？

谢谢！

the redefine command will help to get the configuration from the odm, so after that you can use the rmlvcopy and reducevg command. but it does not mean to delete it from the rootvg , it will depend on the situation. but I think redefinevg command can help you to fix the issue.

For the rootvg volume group, you can use the redefinevg command, which examines every disk in the system to determine which volume group it belongs to
and then updates the ODM. For example:
# redefinevg rootvg

after you can find if that bad disk exists on root vg and decide what to do next.
