1.關(guān)機接好第二塊SCSI硬盤
2.開機進入linux系統(tǒng)，輸入fdisk -l 或者dmesg |grep sdb（這個命令會顯示本機第2塊硬盤的信息）
3.fdisk /dev/sdb
[root@OracleDB ~]# fdisk /dev/sdb
The number of cylinders for this disk is set to 1044.
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

b?? edit bsd disklabel
c?? toggle the dos compatibility flag
d?? delete a partition

p?? print the partition table
q?? quit without saving changes
s?? create a new empty Sun disklabel

v?? verify the partition table
w?? write table to disk and exit
x?? extra functionality (experts only)

最后保存 w
然后fdisk -l
會看到/dev/sdb1這個分區(qū)
下面把這個分區(qū)格式化成ext3格式
然后格式化分區(qū)，創(chuàng)建文件系統(tǒng)
mkfs -t ext3 /dev/sdb5，等一會兒就完成了。
創(chuàng)建mount point:
#cd /
#mkdir app
測試是否MOUNT
#mount -t ext3 /dev/sdb5?? /app
一舉成功。
#umount?? /app
最后修改/etc/fstab，增加一行：
/dev/sdb5?? /app ext3 default 1 2
保存后運行命令
mount -a
結(jié)果ok, cd /app 發(fā)現(xiàn)了lost+found。
