aix更换硬盘出错
一台9111-520服务器，硬盘出现故障，后来更换硬盘，还盘之前的操作如下：
# unmirrorvg rootvg hdisk1
0516-1246 rmlvcopy: If hd5 is the boot logical volume, please run 'chpv -c'
as root user to clear the boot record and avoid a potential boot
off an old boot image that may reside on the disk from which this
logical volume is moved/removed.
0516-1804 chvg: The quorum change takes effect immediately.
0516-1144 unmirrorvg: rootvg successfully unmirrored, user should perform
bosboot of system to reinitialize boot records. Then, user must modify
bootlist to just include: hdisk0.
# lsvg -p rootvg
rootvg:

hdisk0 active 546 112 29..25..00..00..58

# bosboot -ad /dev/hdisk0
bosboot: Boot image is 38357 512 byte blocks.
# bootlist -m normal hdisk0 cd0
# bootlist -m normal -o
hdisk0 blv=hd5
cd0
然后diag点亮磁盘，但是没有窒息感remove而是直接拔的，系统重启，重启后更换新硬盘的时候一直出现问题
# extendvg rootvg hdisk1
0516-1398 extendvg: The physical volume hdisk1, appears to belong to
another volume group. Use the force option to add this physical volume
to a volume group.
0516-792 extendvg: Unable to extend volume group.

以前删除的盘的信息还在odm库里，虽然你已经从vg里删除了hdisk1的盘，但是odm库的信息还是存在的！就是说你少了一步（rmdev -dl hdisk1 -R）的操作，你加的新盘，cfgmgr -v的新盘肯定不是hdisk1，而是其他盘的（如hdisk2等等）lspv看一下pv的信息，留下hdisk0，其他盘删除（rmdev -dl hdisk* -R）拔掉。重新插入新盘，cfgmgr -v扫盘，用（redev -l hdisk认出盘符 hdisk改成需要的盘符）给盘加盘的pvid（chdev -l hdisk1 -a pv=yes）把盘加到vg里 extendvg rootvg hdisk1 就行了！

我用和系统一样的光盘修复后，exit退出后出现下面的错误！但是启动显示
/etc/getrootfs[586]: 4226 Killed
/etc/getrootfs[586]: 4228 Killed
/etc/getrootfs[586]: 4230 Killed
/etc/getrootfs[586]: 4232 Killed
....
就停住，不能进入到命令符＃，后来求证是主机中ML的版本和光盘上的不一致而引起的。
而且你前面出的问题前面人已经说的挺清楚了，说是你在拔硬盘的时候没有执行rmdev，
所以在插上新硬盘的时候，cfgmgr会生成新的HDISKX，新的硬盘就是这个PV，你直接将
这个PV加入VG用就可以了。收起
