1） 环境：
V480R 2个72G硬盘
分区： / --> c1t0d0s0(剩下的硬盘空间) ; swap --> c1t0d0s1 (8G) ； c1t0d0s7（50M）
2） 方法：
网上查的，主要步骤如下：
prtvtoc /dev/rdsk/c1t0d0s2 | fmthard -s - /dev/rdsk/c1t1d0s2
metadb -a -f -c 3 c1t0d0s7 c1t1d0s7
metainit -f d10 1 1 c1t0d0s0
metainit d20 1 1 c1t1d0s0
metainit d0 -m d10
cp /etc/vfstab /etc/vfstab.bak
metaroot d0
lockfs -fa
reboot
下面做swap的镜像
metainit -f d11 1 1 c1t0d0s1
metainit d21 1 1 c1t1d0s1
metainit d1 -m d11
下面做子镜像
metattach d0 d20
metattach d1 d21
metastat | grep % /* 这时我可以看到同步，从1%---到9%，但结束收的状态不是ok状态；
修改vfstab表，用init 6 重启系统
3） 当前状态

4） 我用metasync 命令重新同步，可以看到%比 从1到99%，也重启了，但状态还是如下。

请问各位大侠，这个对吗？ 如果不对，我看如何做，请告诉我具体命令，谢谢。初次安装，请指教
