在不同容量硬盤之間拷貝安裝Unix的方法：

在開始硬盤對拷之前，首先應(yīng)將已安裝好系統(tǒng)的源盤和空白目標(biāo)盤分別設(shè)置跳線，安裝在計算機(jī)上。開機(jī)，進(jìn)入CMOS設(shè)置兩塊硬盤的參數(shù)，然后進(jìn)入源盤的超級用戶root，就可以開始拷貝了。 以下是在digital P200微機(jī)上，SCO Open Server Release 5環(huán)境下進(jìn)行硬盤對拷的過程。 1.增加一塊硬盤 ＃mkdev hd 1 0 Your root hard disk is attached to an IDE controller. Pick one of the choices below or you may quit and Invoke mkdev hd －u for a detail usage message. 1)Add a hard disk to IDE controller 2)Add a hard disk to SCSI controller 3)Add a hard disk to an IDA controller(EISA) Enter 1,2,3,or enter 'q' to quit:(輸入1) …… If you wish to exit the entire installation at this menu, Press the <DEL>key. Hard Disk Drive 1 Configuration 1.Display current disk parameters 2.Modify current disk parameters 3.Select default disk parameters Enter an option or 'q' to quit: (這是dkinit程序的菜單。在此可以選1顯示目標(biāo)硬盤參數(shù)，如不符要求，可選2進(jìn)行修改，然后輸入q繼續(xù)) …… 1.Display Partition Table 2.Use Entire Disk for UNIX 3.Use Rest of Disk for UNIX 4.Create UNIX Partition 5.Activate Partition 6.Delete Partition 7.Create Partition Enter your choice or 'q' to quit: (這是fdisk程序的菜單。在此可以對目標(biāo)硬盤按需要進(jìn)行分區(qū)，然后輸入q繼續(xù)) 　 …… 1.Print Current Bad Track Table 2.Scan Disk (You may choose Read－Only or Destructive later) 3.Add EntrIEs to Current Bad Track Table by Cylinder/Head Number 4.Add Entries to Current Bad Track Table by Sector Number 5.Delete Entries Individually from Current Bad Track Table 6.Delete All Entries from Bad Track Table Please enter your choice or 'q' t 廯 t: (這是badtrk程序的菜單，選擇2可以掃描查找硬盤上有問題的磁道，并對應(yīng)到硬盤別處的正常磁道上，另外還建立一個壞道表。輸入q繼續(xù)) Enter the number of bad tracks to allocate space for (or press<return>to use the recommended value of 15): (回車) There are 2110657 blocks in the UNIX area. Please enter the number of file systems you want this area To be divided into，or press<Return>to get the default of 2 file system(s). (回車) The layout of the filesystems and swap area is now prepared. Do you wish to make any manual adjustments to the sizes or names of the filesystems or swap area before they are created on the hard disk?(y/n) (輸入n) Making filesystems Hard disk initialization procedure completed. 2.用dd命令將SCO UNIX硬盤自舉程序從源盤拷入目標(biāo)盤 ＃dd if=/dev/hd0a of=/dev/hdla bs=1024 count=40 3.用divvy命令在目標(biāo)盤上建立可安裝的文件系統(tǒng) ＃divvy－im /dev/rhdla There are 2095537 lk blocks in the UNIX area. Between 16000 and 512000 lk blocks should be reserved for the swap area. Please enter the swap－space allocation ,or press <Return> To get the default allocation of 24000 lk blocks: (回車) There are 2095537 lk blocks in the UNIX area. Between 15000 and 64000 lk blocks should be reserved for the boot filesystem. Please enter the boot－space allocation,or press <Return> To get the default allocation of 20000 lk blocks: (回車) Do you want a separate /u filesystem?(y/n) (輸入n) The layout of the filesystems and swap area is now prepared. Do you wish to make any manual adjustments to the sizes or names of the filesystems or swap area before they are created on the hard disk?(y/n) (輸入n) Making filesystems 4.用divvy 命令查看并修改內(nèi)分區(qū)(division)名 ＃divvy/dev/rhdla Name Type New FS ＃ First Block Last Block dll50　EAFS　no　0 0 19999 d1151 NON Fsno　1　20000 43999 HTFSno　2　44000 2045725 Not USEDno　3　－ － Not USEDno　4　－ － Not USEDno　5　－ － recover NON FS　no　6　2045726 2045735 hdla WHOLE　DISKno　7　0 2061831 2045736 lk blocks for divisions,16096 lk blocks reserved for the system. n[ame] Name or rename a division. c[reate] Create a new file system on this division. t[ype] Select or change filesystem type on new filesystems. p[revent] Prevent a new file system from being created on this. s[tart] Start a division on a different block. e[nd] End a division on a different block. r[estore] Restore the original division table. Please enter your choice or 'q' to quit: (輸入n修改內(nèi)分區(qū)名。在此分別將0，1，2內(nèi)分區(qū)名修改為rb ,rs,rr) i[nstall] Install the division set－up shown. r[eturn] Return to the previous menu. e[xit] Exit without installing a division table. Please enter your choice: (輸入i將內(nèi)分區(qū)情況安裝在目標(biāo)盤上) Making filesystems. 5.將目標(biāo)盤引導(dǎo)文件系統(tǒng)安裝到源盤上，并拷貝其內(nèi)容 ＃mount/dev/rb/mnt ＃cd/stand ＃find.－print|cpio－pdumv /mnt ＃umount/mnt 6.將目標(biāo)盤根文件系統(tǒng)安裝到源盤上，并拷貝其內(nèi)容 ＃ mount/dev/rr/mnt ＃find/－mount print|cpio－pdumv/mnt 7.建立目標(biāo)盤根文件系統(tǒng)中的文件系統(tǒng)安裝點(diǎn) ＃cd /mnt ＃mkdir mnt stand;chmod 755 mnt stand;chgrp bin mnt stand ＃umount /mnt 至此，拷貝完畢。
