过程：
1. 识别新增硬盘
root:/# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c0d0 <DEFAULT cyl 1302 alt 2 hd 255 sec 63>
/pci@0,0/pci-ide@7,1/ide@0/cmdk@0,0
Specify disk (enter its number): ^C
root:/# devfsadm
root:/# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c0d0 <DEFAULT cyl 1302 alt 2 hd 255 sec 63>
/pci@0,0/pci-ide@7,1/ide@0/cmdk@0,0
1. c0d1 <DEFAULT cyl 1303 alt 2 hd 255 sec 63>
/pci@0,0/pci-ide@7,1/ide@0/cmdk@1,0
Specify disk (enter its number): 1
注意：两次format命令显示内容的区别。第二次系统识别出新增硬盘c0d1。
在此次试验中使用命令 devfsadm命令识别出新增硬盘，网络上还有一些其他方法。
2. 格式化新增硬盘
root:/# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c0d0 <DEFAULT cyl 1302 alt 2 hd 255 sec 63>
/pci@0,0/pci-ide@7,1/ide@0/cmdk@0,0
1. c0d1 <DEFAULT cyl 1302 alt 2 hd 255 sec 63>
/pci@0,0/pci-ide@7,1/ide@0/cmdk@1,0
