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： Searching for disks...done AVAILABLE DISK SELECTIONS: 0. c0t0d0 /pci@1f,4000/scsi@3/sd@0,0 1. c0t1d0 /pci@1f,4000/scsi@3/sd@1,0 2. c0t2d0 /pci@1f,4000/scsi@3/sd@2,0 3. c0t3d0 /pci@1f,4000/scsi@3/sd@3,0 Specify disk (enter its number): 2 selecting c0t2d0 [disk formatted] Warning: Current Disk has mounted partitions. FORMAT MENU: disk - select a disk type - select (define) a disk type partition - select (define) a partition table current - describe the current disk format - format and analyze the disk repair - repair a defective sector label - write label to the disk analyze - surface analysis defect - defect list management backup - search for backup labels verify - read and display labels save - save new disk/partition definitions inquiry - show vendor, PRoduct and revision volname - set 8-character volume name ! quit format> partition PARTITION MENU: 0 - change `0' partition 1 - change `1' partition 2 - change `2' partition 3 - change `3' partition 4 - change `4' partition 5 - change `5' partition 6 - change `6' partition 7 - change `7' partition select - select a predefined table modify - modify a predefined partition table name - name the current table print - display the current table label - write partition map and label to the disk ! quit partition> modify partition>label partition>quit format>save 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 |
