1.查看系统版本:
# oslevel
7.1.0.0
# chdev -l hdisk1 -a pv=clear
hdisk1 changed
# chdev -l hdisk1 -a pv=yes
hdisk1 changed
# lspv
hdisk0 00c96db097dbd092 rootvg active
hdisk1 00c96db029fbd85f None
hdisk2 00c96db00b1e37d5 None
# extendvg -f rootvg hdisk1
# 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 hdisk0.
2.查看mirror是否完成:
# lsvg -l rootvg
rootvg:
LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT
hd5 boot 1 2 2 closed/syncd N/A
hd6 paging 1 2 2 open/syncd N/A

livedump jfs2 1 2 2 open/syncd /var/adm/ras/livedump
lp=2pp,是指一份lp的数据,对应两份pp的数据,物理上是有2份拷贝的
