在 Linux 下设备文件放在 /dev 目录下。
IDE 硬盘 第一块 /dev/hda 、第二块硬盘 /dev/hdb 、第三块 /dev/hdc.
SCSI 硬盘 第一块 /dev/sda 、第二块硬盘 /dev/sdb 、第三块 /dev/sdc
Hp raid or cpq array ( 这一点要注意 ).
第一个 logic driver /dev/cciss/c0d0
第二个 logic driver /dev/cciss/c0d1
以添加 SCSI 硬盘为例：
[root@linux /]# fdisk /dev/sdb 用 fdisk 工具来创建新的分区
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won"t be recoverable.
The number of cylinders for this disk is set to 17366.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): m 显示主菜单
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
l list known partition types
m print this menu
n add a new partition
o create a new empty DOS partition table
p print the partition table
q quit without saving changes
s create a new empty Sun disklabel
t change a partition"s system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)
Command (m for help): n 创建新分区
Command action
e extended 扩展的分区
p primary partition (1-4) 主分区
p 创建主分区
Partition number (1-4): 1
First cylinder (1-17366, default 1): 1
Last cylinder or +size or +sizeM or +sizeK (1-17366, default 17366): +10000M 选择分区大小
Command (m for help): w 保存退出
The partition table has been altered!
Calling ioctl() to re-read partition table.
WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
The kernel still uses the old table.
The new table will be used at the next reboot.
Syncing disks.
[root@linux /]# mkfs -t ext3 /dev/sdb1 将我创建的第一个分区 sdb1 格式化
