在操作系统安装结束后  
安装DiskSuite\_4.2.1软件及相关补丁  
以下以实力的方式介绍“引导盘镜像操作”  
例子中操作系统分区定义如下：  
c0t0d0s0 /  
c0t0d0s1 swap  
c0t0d0s3 /var  
c0t0d0s4 (metaDB\*3)  
c0t0d0s5 /opt  
c0t0d0s6 /usr  
c0t0d0s7 /export/home  
用root用户登陆  
运行以下命令：  
\# prtvtoc /dev/rdsk/c0t0d0s2 >; boot-vtoc.tab  
\# fmthard -s boot-vtoc.tab /dev/rdsk/c0t1d0s2  
以上命令将第2硬盘的文件分区表调整为和引导盘一致  
运行以下命令：  
\# metadb -afc 3 c0t0d0s4  
\# metadb -afc 3 c0t1d0s4  
\# metainit -f d21 1 1 c0t0d0s0  
\# metainit d22 1 1 c0t1d0s0  
\# metainit -f d24 1 1 c0t0d0s1  
\# metainit d25 1 1 c0t1d0s1  
\# metainit -f d27 1 1 c0t0d0s3  
\# metainit d28 1 1 c0t1d0s3  
\# metainit -f d31 1 1 c0t0d0s5  
\# metainit d32 1 1 c0t1d0s5  
\# metainit -f d34 1 1 c0t0d0s6  
\# metainit d35 1 1 c0t1d0s6  
\# metainit -f d37 1 1 c0t0d0s7  
\# metainit d38 1 1 c0t1d0s7  
  
\# metainit d20 -m d21  
\# metainit d23 -m d24  
\# metainit d26 -m d27  
\# metainit d30 -m d31  
\# metainit d33 -m d34  
\# metainit d36 -m d37  
  
\# metaroot d20  
\# lockfs -fa  
  
修改/etc/vfstab文件为如下：  
  
\#device device mount FS fsck mount mount  
\#to mount to fsck point type pass at boot options  
\#  
\#/dev/dsk/c1d0s2 /dev/rdsk/c1d0s2 /usr ufs 1 yes -  
fd - /dev/fd fd - no -  
/proc - /proc proc - no -  
  
\#/dev/dsk/c0t0d0s3 - - swap - no -  
/dev/md/dsk/d26 - - swap - no -  
  
\#/dev/dsk/c0t0d0s0 /dev/rdsk/c0t0d0s0 / ufs 1 no -  
/dev/md/dsk/d20 /dev/md/rdsk/d20 / ufs 1 no -  
  
\#/dev/dsk/c0t0d0s6 /dev/rdsk/c0t0d0s6 /usr ufs 1 no -  
/dev/md/dsk/d33 /dev/md/rdsk/d33 /usr ufs 1 no -  
  
\#/dev/dsk/c0t0d0s1 /dev/rdsk/c0t0d0s1 /var ufs 1 no -  
/dev/md/dsk/d23 /dev/md/rdsk/d23 /var ufs 1 no -  
  
\#/dev/dsk/c0t0d0s7 /dev/rdsk/c0t0d0s7 /export/home ufs 2 yes -  
/dev/md/dsk/d36 /dev/md/rdsk/d36 /export/home ufs 2 yes -  
  
\#/dev/dsk/c0t0d0s5 /dev/rdsk/c0t0d0s5 /opt ufs 2 yes -  
/dev/md/dsk/d30 /dev/md/rdsk/d30 /opt ufs 2 yes -  
  
swap - /tmp tmpfs - yes -  
  
至此，引导盘镜像操作的第一步完成  
  
运行以下命令重新引导操作系统  
  
\# sync  
\# sync  
\# sync  
\# reboot  
  
做数据同步  
\# metattach d20 d22  
\# metattach d23 d25  
\# metattach d26 d28  
\# metattach d30 d32  
\# metattach d33 d35  
\# metattach d36 d38  
以上步骤执行时间较长  
  
  
主引导盘损坏的恢复（主引导盘为c0t0d0）  
删除损坏的replicas  
\# metadb -i \#查看状态  
\# metadb -d c0t0d0s4 \#删除replicas  
停机，换盘  
\# sync  
\# sync  
\# init 5  
  
从备用盘引导系统(使用Stop+A 使系统进入ok状态)  
ok boot disk1  
设置新盘分区  
\# prtvtoc /dev/rdsk/c0t1d0s2 >; boot-vtoc.tab  
\# fmthard -f boot-vtoc.tab /dev/rdsk/c0t0d0s2  
再创建replicas  
\# metadb -afc 3 c0t0d0s4  
重连接新设备到主mirror，并同步  
\# metareplace -e d20 c0t0d0s0  
d20: device c0t0d0s0 is enabled  
\# metareplace -e d23 c0t0d0s1  
d20: device c0t0d0s1 is enabled  
\# metareplace -e d26 c0t0d0s3  
d20: device c0t0d0s3 is enabled  
\# metareplace -e d30 c0t0d0s5  
d20: device c0t0d0s5 is enabled  
\# metareplace -e d33 c0t0d0s6  
d20: device c0t0d0s6 is enabled  
\# metareplace -e d36 c0t0d0s7  
d20: device c0t0d0s7 is enabled  
以上步骤执行时间较长
