What is the difference between a management port, a maintenance port, and a serial port on the OceanStor V3 device?
[Functions]
All three ports are used for managing and maintaining storage systems. However:
A management port is connected using a network cable to a network port on a maintenance terminal.
A maintenance port can only be used by Huawei engineers in emergencies. In addition, it cannot be connected to the same network as a management port; otherwise, network reciprocating may occur, causing network storms. Therefore, do not connect a management port and a maintenance port to the same switch.
A serial port is connected using a serial cable to its peer serial port on a maintenance terminal.
[Login mode]
By a serial port:
After connecting a maintenance terminal to a controller enclosure, you can use a terminal-emulation program (such as PuTTY) to log in to the command-line interface (CLI) of a storage system. A pair of user name and password is required by the login.
By a management port:
1. After connecting a maintenance terminal to a controller enclosure, you can use a terminal-emulation program (such as PuTTY) to log in to the CLI of a storage system. The IP address of the management port and a pair of user name and password are required by the login.
2. Alternatively, you can access the IP address of the management port from a browser to log in to DeviceManager. The IP address of the management port and a pair of user name and password are required by the login.
Note: A maintenance port is used by Huawei engineers in emergencies. Therefore, its login mode will not be introduced here.
