AIX 解除镜像再重建同步

扩展fs发现pv状态变成removed，用chpv -v -a hdisk即可，至于什么原因造成removed？
一.解除vg mirrorunmirrorvg vgname hdiskx hdiskxx，后面跟被踢掉的hdisk

五.smitty vg - mirror vg
另外一个比较悲剧，lv镜像落在了同一边的存储，恰好这个存储的pv变成了removed状态
一.解除vg mirror

pv1 2 3 4一组，pv5 6 7 8一组，p50oralv上一个对应hdisk1 hdisk4落在了同一个存储上
备份数据
1.将这4个removed的盘在V7000上做flashcopy，挂载到新的AIX主机，
mkvdev -vdev hdisk3 -vadapter vhost0 -dev p50_data01
mkvdev -vdev hdisk4 -vadapter vhost0 -dev p50_data02
mkvdev -vdev hdisk5 -vadapter vhost0 -dev p50_data03
mkvdev -vdev hdisk6 -vadapter vhost0 -dev p50_data04
mkvdev -vdev hdisk7 -vadapter vhost0 -dev p50_bak
2.在vioc强制导入vg
importvg -y datavg -f hdiskxx
3.数据库可以正常启动

- 2.3 查看lv的pp分布已经在2组hdisk，1-4,5-8

- 2.4 本来想着删除全部的lv副本，重新mirrorvg，换一种方式，将没有副本的lv全部建一个副本
- 2.5 除了lv
p50oralv有副本外，其他的lv只存在hdisk5-8上，将没有副本的lv创建副本到hdisk1-4上
