  两个用途,即格式化硬盘和重新对硬盘分区.

  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
