Solaris format命令

云知道

【Solaris format命令】
由于它的破壞性極大，使用時(shí)一定要小心!
兩個(gè)用途，即格式化硬盤和重新對硬盤分區(qū).
1)格式化硬盤
最好進(jìn)入單用戶模式
#format
系統(tǒng)會(huì)顯示所有的硬盤并讓我們選擇要操作硬盤：

使用命令newfs來為每一個(gè)分區(qū)創(chuàng)建文件系統(tǒng):
newfs /dev/rdsk/c?t?d?s?
硬盤包含啟動(dòng)分區(qū)(根分區(qū))，我們需要手動(dòng)安裝啟動(dòng)模塊
#reboot cdrom -s (從光盤啟動(dòng)，并進(jìn)入單用戶模式)
#mount /dev/dsk/c0t1d0s0 /mnt (將系統(tǒng)根分區(qū)掛接到mnt目錄下)
#cp /ufsboot /mnt
#installboot /lib/fs/ufs/bootblk /dev/rdsk/c0t1d0s0 (安裝啟動(dòng)模塊)
#umount /mnt (卸下掛接)
#reboot (重啟動(dòng))

2) 重新分區(qū)
format命令也可以對硬盤進(jìn)行重新分區(qū) 。重新分區(qū)后，受影響分區(qū)上的所有文件將被清除
要對該分區(qū)表命名，SAVE退出format 命令 。分區(qū)結(jié)束后，我們要用newfs命令為改變的分區(qū)創(chuàng)建文件系統(tǒng)
