输入IP地址，要保存的名字，点击保存
首次连接，会出现以下提示。单击是。
根据提示，输入服务器用户名和密码。密码不会显示在屏幕上。输入完成后回车。
格式化和挂载数据盘
运行fdisk -l命令查看数据盘。
[root@xxxx ~]# fdisk -l Disk /dev/xvda: 42.9 GB, 42949672960bytes 255 heads, 63 sectors/track, 5221cylinders Units = cylinders of 16065 * 512 = 8225280bytes Sector size (logical/physical): 512 bytes / 512bytes I/O size (minimum/optimal): 512 bytes / 512bytes Disk identifier: 0x00078f9c Device Boot Start End Blocks Id System /dev/xvda1 * 1 5222 41940992 83Linux Disk /dev/xvdb: 5368 MB, 5368709120bytes 255 heads, 63 sectors/track, 652cylinders Units = cylinders of 16065 * 512 = 8225280bytes Sector size (logical/physical): 512 bytes / 512bytes I/O size (minimum/optimal): 512 bytes / 512bytes Disk identifier: 0x00000000
执行命令进行分区
fdisk /dev/xvdb根据提示，依次输入n，p，1，两次回车，wq，分区就开始了。
[root@xxx ~]# fdisk /dev/xvdb Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklab el Building a new DOS disklabel with disk identifier 0x33eb5059. Changes will remain in memory only, until you decide to writethem. After that, of course, the previous content won't be recoverable. Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite) WARNING: DOS-compatible mode is deprecated.

执行fdisk -l命令，查看新的分区。新分区 xvdb1 已经创建好。如下面示例中的/dev/xvdb1。
[root@xxx ~]# fdisk -l Disk /dev/xvda: 42.9 GB, 42949672960bytes 255 heads, 63 sectors/track, 5221cylinders Units = cylinders of 16065 * 512 = 8225280bytes Sector size (logical/physical): 512 bytes / 512bytes I/O size (minimum/optimal): 512 bytes / 512bytes Disk identifier: 0x00078f9c Device Boot Start End Blocks Id System /dev/xvda1 * 1 5222 41940992 83Linux Disk /dev/xvdb: 5368 MB, 5368709120bytes 255 heads, 63 sectors/track, 652cylinders Units = cylinders of 16065 * 512 = 8225280bytes Sector size (logical/physical): 512 bytes / 512bytes I/O size (minimum/optimal): 512 bytes / 512bytes Disk identifier: 0x33eb5059 Device Boot Start End Blocks Id System /dev/xvdb1 1 652 5237158+ 83 Linux
执行下列命令，对新分区进行格式化
mkfs.ext3 /dev/xvdb1执行下列命令写入新分区信息。
echo '/dev/xvdb1/mnt ext3 defaults 0 0'>> /etc/fstab完成后，可以使用 cat /etc/fstab 命令查看。
