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:

# 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.
# lsvg -p rootvg
