(Optional) Building a Remote Maintenance Environment

(Optional) Building a Remote Maintenance Environment

After building a remote maintenance environment, you can remotely manage and maintain a storage system.

Prerequisites

  • Before building a remote maintenance environment, ensure that PSTN phones and external modems are configured in equipment rooms.
  • Each controller is configured with one serial port connected to one modem. Select the external modem based on your requirements.

Context

You can log in to the CLI through a storage system serial port to perform remote management and maintenance. This document uses two 56 K modems that remotely access the storage system in PSTN dialup mode (under Windows OS) as an example to describe configuring modems for remote maintenance.

NOTE:

The PSTN ensures enhanced data security as its data is not transmitted over the Internet. Meanwhile, you are advised to power off the modem to further ensure security when you do not need to perform remote maintenance.

To implement remote maintenance, one remote modem and one local modem are required.

Figure 10-26 shows the network topology.

Figure 10-26 Remote maintenance network topology

In the Figure 10-26, note the following information:

  • Remote modem

    The remote modem is connected to the storage system serial port as an answer end.

  • Local modem

    The local modem is connected to the maintenance terminal serial port as a call end.

On this network, a remote maintenance request is handled in this sequence: maintenance terminal serial port —> local modem —> PSTN —> remote modem —> storage system serial port.

Procedure

  1. Configure a remote modem as the answer end.

    NOTE:

    To configure the remote modem, you will need to connect the remote modem to a maintenance terminal temporarily.

    1. Connect the modem to the remote power supply. Connect the local modem serial port to the maintenance terminal serial port with a serial cable. Connect the remote modem LINE port to the PSTN with a telephone cable.
    2. Run PuTTY.

      The PuTTY Configuration dialog box is displayed, as shown in Figure 10-27.

      Figure 10-27 PuTTY Configuration dialog box

    3. In Connection type, select Serial. In Speed, enter 115200.
    4. Click Open.
    5. Type at and press Enter. The screen displays:
      OK!
    6. Run the following AT commands in a sequence:

      Type ats0=1 and press Enter. The screen displays:

      OK!

      Type at&d0 and press Enter. The screen displays:

      OK!

      Type at&k0 and press Enter. The screen displays:

      OK!

      Type at&w and press Enter. The screen displays:

      OK!

  2. Configure a local modem as the call end.

    1. Connect the modem to the nearest power supply. Connect the local modem serial port to the maintenance terminal serial port with a serial cable. Connect the local modem LINE port to the PSTN with a telephone cable.
    2. Run PuTTY, and perform Step 1.2 to Step 1.4 in Step 1.
    3. Type at and press Enter. The screen displays:
      OK!
    4. Set initial parameters for the local modem.

      Type at&f&w and press Enter. The screen displays:

      OK!

  3. Set up the connection.

    Before setting up the connection, ensure that the remote modem is disconnected from the storage device. Otherwise, the storage system serial port will stop responding because a large amount of data is sent from the remote modem during modem dialup. When both the remote modem and the local modem have dialed up to the network, connect the remote modem to the storage device with a serial cable.

    1. Run PuTTY on the maintenance terminal, and perform Step 1.2 to Step 1.4 in Step 1.
    2. Type at and press Enter. The screen displays:
      OK!
    3. Type atdt XXX-YYYYYYYYY and press Enter for dialup.

      When both the remote modem and the local modem have been dialed up to the network, the baud rate is CONNECT. (For modems of different manufacturers, the screen displays vary.)

      NOTE:
      • XXX-YYYYYYYYY (area code+phone number) indicates the telephone number of the remote site. This phone number must allow direct dialup.
      • During dialup, the OH indicator of the local modem is steady on.
      • If error messages are displayed, such as NO CARRIER, BUSY, NO ANSWER, and ERROR after the atdt command is executed, check the remote modem configurations and then retries the dialup.
    4. After the local modem is connected to the remote modem, connect the remote modem to the storage device with a serial cable. Then press any key to go to the CLI.
    5. Enter user name and password when prompted.
      NOTE:

      No local echo is displayed when entering a password, for security reasons.

      The default user name for the storage system is admin, and the password is Admin@storage.

      You are advised to change the default login password immediately after you log in to the storage system for the first time and to periodically change your login password in the future. This reduces password leakage risks. For details about how to change a password, see the Administrator Guide specific to your product.

       
      Storage login: admin 
      Password: 
        System Name     : xxxx 
        Health Status : Normal 
        Running Status  : Normal 
        Total Capacity  : 19.991TB 
        SN              : XXXXXXXXXXXXXX 
        Location        : 
        Product Model : xxxx 
        Product Version : xxxx 
        Time            : 2013-09-17/17:37:01 +08:00     
    6. The CLI login succeeds.

      The storage device can now be remotely managed and maintained.
