Operation and Maintenance
The storage systems can be operated and maintained by using DeviceManager and the command-line interface (CLI), adapting to different environments and user habits.
Introduction to DeviceManager
Figure 9-1 shows the DeviceManager main window.
Table 9-1 describes the components of the DeviceManager main window.

Fault statistics area |
The fault statistics area shows the number of each level of system faults, helping users understand the running status of a storage system. |
Users can log in to DeviceManager using a common browser.
To master GUI-based operations, you are advised to read this document and practice the operations using the DeviceManager Demo. As a simulation program of storage system management software, the DeviceManager Demo simulates configuration and management operations on a storage system.
Introduction to the CLI
After logging in to the storage system through CLI, you can query, set, manage, and maintain the storage system.
Users need to log in to the CLI by using terminal software, such as the HyperTerminal provided by Windows, or PuTTY.
There are two ways to log in to the CLI.
- Log in through a serial port of a storage system. To connect to a serial port, the maintenance terminal must be located next to the storage system. Therefore, this login mode is applicable to the scenario where a user does not know the management IP address of a storage system or a storage system is faulty.
- Log in through a management network port of a storage system. When there are reachable routes, a user can log in to the CLI by entering the IP address of the management network port of a storage system in the terminal software. IP networks are easily accessible. Therefore, a user can log in to a storage system remotely, and this login mode is more popular.
