PV状态是removed或者missing

pv的状态是removed或者missing，网上说磁头信息不一致

使用 od -x /dev/hdisk1 | more 更新pvid，比较麻烦，我用fuser察看到没有进程访问，就重新先脱离vg然后再镜像

hdisk1状态missing解决办法
1.lspv

2.lsvg

3.reducevg rootvg hdisk1
4.rmdev -dl hdisk1
5.cfgmgr
6.chdev -l hdisk1 -a pv=yes
7.extendvg rootvg hdisk1
8.mirrorvg rootvg hdisk1
0516-1804 chvg: The quorum change takes effect immediately.
0516-1126 mirrorvg: rootvg successfully mirrored, user should perform
        bosboot of system to initialize boot records.  Then, user must modify
        bootlist to include:  hdisk1 hdisk2.
9.bosboot -ad /dev/hdisk1
  bosboot: Boot image is 39122 512 byte blocks.
10.bootlist -m normal -o
   hdisk2 blv=hd5
11.bootlist -m normal hdisk2 hdisk1
12.bootlist -m normal -o
   hdisk2 blv=hd5
   hdisk1 blv=hd5
