How Can I Obtain the Mapping Between Disk Partitions and Disk Devices on a Linux ECS?

For a Xen ECS running Linux, its disk partitions correspond to disk devices. This section uses a Linux ECS running Red Hat Enterprise Linux 7 as an example to describe how to obtain the mapping between disk partitions and disk devices.

For KVM or QingTian instances, see How Do I Obtain My Disk Device Name in the ECS OS Using the Device Identifier Provided on the Console?

1. Log in to the Linux ECS running Red Hat Enterprise Linux 7 as user root.
2. Right-click in the blank area of the desktop and choose Open Terminal from the shortcut menu.

3. Run the following command to view disk partitions and disk devices:

   fdisk -l

   Table 1 lists the mapping between disk partitions and disk devices.
