Solaris format命令

由于它的破坏性极大，使用时一定要小心!

两个用途，即格式化硬盘和重新对硬盘分区.

1)格式化硬盘

最好进入单用户模式

#format

系统会显示所有的硬盘并让我们选择要操作硬盘：

使用命令newfs来为每一个分区创建文件系统:

newfs /dev/rdsk/c?t?d?s?

硬盘包含启动分区(根分区)，我们需要手动安装启动模块

#reboot cdrom -s (从光盘启动，并进入单用户模式)

#mount /dev/dsk/c0t1d0s0 /mnt (将系统根分区挂接到mnt目录下)

#cp /ufsboot /mnt

#installboot /lib/fs/ufs/bootblk /dev/rdsk/c0t1d0s0 (安装启动模块)

#umount /mnt (卸下挂接)

#reboot (重启动)

2) 重新分区

format命令也可以对硬盘进行重新分区。重新分区后，受影响分区上的所有文件将被清除

要对该分区表命名，SAVE退出format 命令。分区结束后，我们要用newfs命令为改变的分区创建文件系统
