系統裝完了，客戶要求兩塊盤做一個鏡象，對於我來說是大姑娘上轎--頭一回。SOLARIS10已經自帶了DiskSuite軟件，可以直接做鏡象，於是找來資料，從下午兩點半弄到下午6點鐘，同步可能要4個小時，基本上是晚上12點才能同步完，當然，是因為中間搞錯了，花時間來整好了，新手都是難免的~~基本情況是機器配有兩塊硬盤（c1t0d0，c1t1d0）各140G，裝系統的時候選0號盤c1t0d0，分區是這樣的：s0給/，s1給/var，s2是整個硬盤，s3給swap，s4給/export/home，s5給/opt，s6和s7各留了200M用來做鏡象用（刪除文件系統名，只留空間），此文檔不含理論，只有實際操作，涉及到的命令請參考其他文檔，下面是詳細的鏡象過程，用root用戶操作。
--------------------------------------
實施之前做好規劃，規劃如下：
--根分區
d0 d10 d20 / s0
--VAR分區
d1 d11 d21 /var s1
--SWAP分區
d2 d12 d22 swap s3
--export/home分區
d3 d13 d23 /export/home s4
--/opt分區
d4 d14 d24 /opt s5
d0，d1，d2，d3，d4為對應各個分區的metadevice名字；d10等是每個metadevice對應的子鏡像
--------------------------------------
一、先用format和df -k查看一下磁盤的情況0號盤是c1t0d0，1號盤是c1t1d0

二、備份一下/etc/vfstab和/etc/system文件，以備不時之需
#cp /etc/vfstab /etc/vfstab.bak
#cp /etc/system /etc/system.bak
三、磁盤分區同步（使兩塊盤分區大小一樣）
# 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、做根分區的兩路子鏡像
# metainit -f d10 1 1 c1t0d0s0
d10: Concat/Stripe is setup
# metainit d20 1 1 c1t1d0s0
d20: Concat/Stripe is setup
六、制作根分區的鏡像盤
# metainit d0 -m d10
d0: Mirror is setup
七、修改vfstab文件中關於根分區的項目
-----------------------------------------------------------------------------------
# more /etc/vfstab
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
#
fd - /dev/fd fd - no -

九、做/var分區的兩路子鏡像和/var分區的鏡象盤
# 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

"/etc/vfstab" 14 lines, 510 characters
十八、重啟系統
#reboot
-------------------------------------------------------
注意：
做到這步時，我犯了一個錯誤，用solaris的話來說，是fatal的，我vi時把本該寫成/dev/md/dsk/d3 /dev/md/rdsk/d3 /export/home的卻寫成了/dev/md/dsk/d4 /dev/md/rdsk/d4 /export/home，因為/export/home是在s4分區，我習慣性的把s4對應成了d4了，結果重啟後檢查文件系統時就啟不來了。於是查資料，解決過程如下：
現在使用的是完整的機器，也就是說有鼠標鍵盤和顯示器，默認顯示輸出也是SUN顯示器，而不是終端了。
先接上串口線連到終端上來，打開超級終端，此時我發現專用的鍵盤不起作用了，由於默認顯示輸出是SUN顯示器，在超級終端上是看不到輸出，但超級終端上的鍵盤是起作用的（這兩個鍵盤和顯示器的關系讓我出了一身冷汗），於是我在超級終端的鍵盤上按CTRL+BREAK進入OK狀態，通過SUN顯示器可以看到，然後把SOLARIS的啟動盤插入光驅並在OK狀態下輸入boot cdrom -s，用光盤單用戶啟動，就不加載文件系統了。系統起來後，用fsck檢查一遍根分區，命令為fsck -y /dev/rdsk/c1t0d0s0，很快檢查完了，再掛載到臨時文件系統上，命令為mount -F ufs /dev/rdsk/c1t0d0s0 /mnt，由於要用vi來修改/etc/vfstab文件，所以還要設置一下環境變量，(TERM=vt100; export TERM)，這樣就可以vi /etc/vfstab了，改的時候我發現終端鍵盤的方向鍵不能用，只好用H，J，K，L來控制方向了，看來掌握方向是多麼的重要啊，改完保存後，把文件系統卸載下來，命令為umount /mnt，reboot重啟機器，正常了。
-------------------------------------------------------
十九、做/opt分區的兩路子鏡像和/opt分區的鏡象盤
# 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文件中關於/opt分區的項目
# 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、重啟系統
#reboot
二十二、將另外一路子鏡像盤加入到鏡像盤中
# 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、查看鏡象同步狀態
# 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: 5 % done
# metastat | grep %
Resync in progress: 39 % done
Resync in progress: 94 % done
Resync in progress: 9 % done
二十四、同步完之後記得打補丁
