--------------------------------------
实施之前做好规划，规划如下：
--根分区
d0 d10 d20 / s0
--VAR分区
d1 d11 d21 /var s1
--SWAP分区
d2 d12 d22 swap s3
--export/home分区
d3 d13 d23 /export/home s4
--/opt分区
d4 d14 d24 /opt s5
d0，d1，d2，d3，d4为对应各个分区的metadevice名字；d10等是每个metadevice对应的子镜像
--------------------------------------
一、先用format和df -k查看一下磁盘的情况0号盘是c1t0d0，1号盘是c1t1d0

二、备份一下/etc/vfstab和/etc/system文件，以备不时之需
#cp /etc/vfstab /etc/vfstab.bak
#cp /etc/system /etc/system.bak
三、磁盘分区同步（使两块盘分区大小一样）
# prtvtoc /dev/rdsk/c1t0d0s2 | fmthard -s - /dev/rdsk/c1t1d0s2
fmthard: New volume table of contents now in place.
四、制作metadb
# metadb -a -f -c 3 c1t0d0s7 c1t1d0s7
五、做根分区的两路子镜像
# metainit -f d10 1 1 c1t0d0s0
d10: Concat/Stripe is setup
# metainit d20 1 1 c1t1d0s0
d20: Concat/Stripe is setup
六、制作根分区的镜像盘
# metainit d0 -m d10
d0: Mirror is setup
七、修改vfstab文件中关于根分区的项目
-----------------------------------------------------------------------------------
# more /etc/vfstab
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
#

八、改完后重启
#reboot
九、做/var分区的两路子镜像和/var分区的镜象盘
# metainit -f d11 1 1 c1t0d0s1
d11: Concat/Stripe is setup
# metainit d21 1 1 c1t1d0s1
d21: Concat/Stripe is setup
# metainit d1 -m d11
d1: Mirror is setup
十、修改vfstab文件中关于/var分区的项目
# vi /etc/vfstab
"/etc/vfstab" 14 lines, 525 characters
#device device mount FS fsck mount mount

"/etc/vfstab" 14 lines, 510 characters
十八、重启系统
#reboot
-------------------------------------------------------
注意：
做到这步时，我犯了一个错误，用solaris的话来说，是fatal的，我vi时把本该写成/dev/md/dsk/d3 /dev/md/rdsk/d3 /export/home的却写成了/dev/md/dsk/d4 /dev/md/rdsk/d4 /export/home，因为/export/home是在s4分区，我习惯性的把s4对应成了d4了，结果重启后检查文件系统时就启不来了。于是查资料，解决过程如下：
现在使用的是完整的机器，也就是说有鼠标键盘和显示器，默认显示输出也是SUN显示器，而不是终端了。
先接上串口线连到终端上来，打开超级终端，此时我发现专用的键盘不起作用了，由于默认显示输出是SUN显示器，在超级终端上是看不到输出，但超级终端上的键盘是起作用的（这两个键盘和显示器的关系让我出了一身冷汗），于是我在超级终端的键盘上按CTRL+BREAK进入OK状态，通过SUN显示器可以看到，然后把SOLARIS的启动盘插入光驱并在OK状态下输入boot cdrom -s，用光盘单用户启动，就不加载文件系统了。系统起来后，用fsck检查一遍根分区，命令为fsck -y /dev/rdsk/c1t0d0s0，很快检查完了，再挂载到临时文件系统上，命令为mount -F ufs /dev/rdsk/c1t0d0s0 /mnt，由于要用vi来修改/etc/vfstab文件，所以还要设置一下环境变量，(TERM=vt100; export TERM)，这样就可以vi /etc/vfstab了，改的时候我发现终端键盘的方向键不能用，只好用H，J，K，L来控制方向了，看来掌握方向是多么的重要啊，改完保存后，把文件系统卸载下来，命令为umount /mnt，reboot重启机器，正常了。
-------------------------------------------------------
十九、做/opt分区的两路子镜像和/opt分区的镜象盘
# metainit -f d14 1 1 c1t0d0s5
d14: Concat/Stripe is setup
# metainit d24 1 1 c1t1d0s5
d24: Concat/Stripe is setup
# metainit d4 -m d14
d4: Mirror is setup
二十、修改vfstab文件中关于/opt分区的项目
# vi /etc/vfstab
"/etc/vfstab" 14 lines, 510 characters
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
#
fd - /dev/fd fd - no -

二十一、重启系统
#reboot
二十二、将另外一路子镜像盘加入到镜像盘中
# metattach d0 d20
d0: submirror d20 is attached
# metattach d1 d21
d1: submirror d21 is attached
# metattach d2 d22
d2: submirror d22 is attached
# metattach d3 d23
d3: submirror d23 is attached
# metattach d4 d24
d4: submirror d24 is attached
二十三、查看镜象同步状态
# metastat | grep %
Resync in progress: 0 % done
Resync in progress: 0 % done
Resync in progress: 27 % done
Resync in progress: 0 % done
Resync in progress: 0 % done
# metastat | grep %
Resync in progress: 22 % done
Resync in progress: 58 % done
Resync in progress: 56 % done
Resync in progress: 5 % done
# metastat | grep %
Resync in progress: 39 % done
Resync in progress: 94 % done
Resync in progress: 9 % done
二十四、同步完之后记得打补丁
