在操作系統安裝結束後
安裝DiskSuite_4.2.1軟件及相關補丁
以下以實力的方式介紹“引導盤鏡像操作”
例子中操作系統分區定義如下：
c0t0d0s0 /
c0t0d0s1 swap
c0t0d0s3 /var
c0t0d0s4 (metaDB*3)
c0t0d0s5 /opt
c0t0d0s6 /usr
c0t0d0s7 /export/home
用root用戶登陸
運行以下命令：
# prtvtoc /dev/rdsk/c0t0d0s2 > boot-vtoc.tab
# fmthard -s boot-vtoc.tab /dev/rdsk/c0t1d0s2
以上命令將第2硬盤的文件分區表調整為和引導盤一致
運行以下命令：
# 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文件為如下：
#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，引導盤鏡像操作的第一步完成
運行以下命令重新引導操作系統
# sync
# sync
# sync
# reboot
做數據同步
# metattach d20 d22
# metattach d23 d25
# metattach d26 d28
# metattach d30 d32
# metattach d33 d35
# metattach d36 d38
以上步驟執行時間較長
主引導盤損壞的恢復（主引導盤為c0t0d0）
刪除損壞的replicas
# metadb -i #查看狀態
# metadb -d c0t0d0s4 #刪除replicas
停機，換盤
# sync
# sync
# init 5
從備用盤引導系統(使用Stop+A 使系統進入ok狀態)
ok boot disk1
設置新盤分區
# prtvtoc /dev/rdsk/c0t1d0s2 > boot-vtoc.tab
# fmthard -f boot-vtoc.tab /dev/rdsk/c0t0d0s2
再創建replicas
# metadb -afc 3 c0t0d0s4
重連接新設備到主mirror，並同步
# 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
以上步驟執行時間較長
raid 0 +1
metainit d1 1 3 c0t1d0s0 c0t2d0s0 c0t3d0s0
metainit d2 1 3 c0t4d0s0 c0t5d0s0 c0t6d0s0
# metainit d0 -m d1
# metattach d0 d2
raid 1 +0
metainit d1 3 1 c0t1d0s0 1 c0t2d0s0 1 c0t3d0s0
metainit d2 3 1 c0t4d0s0 1 c0t5d0s0 1 c0t6d0s0
# metainit d0 -m d1
# metattach d0 d2
raid 5比較簡單
# metainit d0 -r 1 6 c0t1d0s0 1 c0t2d0s0 1 c0t3d0s0 c0t4d0s0 1 c0t5d0s0 1 c0t6d0s0
