[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.

启动服务器,连接服务器,添加磁盘。
惠普服务器中有一个集成的磁盘阵列控制器,通过它可以配置服务器中的磁盘组成RAID,使系统中存储的数据更安全可靠。我们可以如下操作使NetRAID可用。首先在服务器启动过程中,出现“Press to enter SETUP”提示时,按F2键SETUP,修改服务器的BIOS设置。在服务器的BIOS设置界面中,选择“User Preferences”项,确认“Integrated HP NetRAID”所对应的内容为“Enabled”,并且把它的下一级选项“Included SCSI_A Channel”设为“Yes”,即把磁盘阵列控制器设为可用,并把服务器上的SCSI A通道包括在磁盘阵列控制器中。
惠普的一般都是按f10,里面可以配置阵列,其实很简单,你不会的话打电话给客服,让他们一步步告诉你操作。
接着在服务器重新启动过程中,出现“Option:Experienced users may press for HP NetRAID Express Tools Now.”时,按Ctrl+M组合键进入HP NetRAID快速配置工具。在“Tools Management Menu”菜单下,选择“Configure → Clear Configuration”,清除原先的配置,如以前没有配置RAID,则会出现 “No Existing Configuration to Clear” 的提示;如系统配置了RAID,则提示“Clear Configuration?”,选择“Yes”清除配置。按“Esc”键返回配置菜单,选择“New Configuration”,对 “Proceed?” 回答“Yes”,服务器会开始查找磁盘,查找结束后,所有找到的磁盘会在“New Configuration-ARRAY SelectION MENU”菜单下显示为“READY”就绪状态。
