OceanStor 5300 V3, 5500 V3, 5600 V3, 5800 V3, and 6800 V3 Storage System V300R003

Routine maintenance activities are the most common activities for the storage device, including powering on or off the storage device, managing users, modifying basic parameters of the storage device, and managing hardware components. This document applies to the system administrators who are responsible for carrying out routine maintenance activities, monitoring the storage device, and rectifying common device faults.

Configuring the GSM Modem

Configuring the GSM Modem

After setting the GSM modem, you can configure short message notification in management software. The storage system will send alarm information to a specified mobile phone. You can learn about storage system exceptions and solve them in a timely manner.

Prerequisites

You need to connect the storage device with a GSM modem, make sure you have installed GSM modem.

Context

  • If the GSM modem is not hot-swappable, do not insert or remove it when it is running.
  • If the storage system is enabled with short message notification, the serial port on the controller enclosure serves only the GSM.
  • For a storage system with eight or more controllers, GSM modems can only be configured for the first eight controllers.
  • For a 2 U controller enclosure, you are advised to connect the GSM modem to the serial port of controller A. If the serial port of controller A fails, connect the GSM modem to the serial port of controller B.
  • For a 3 U or 6 U controller enclosure, you are advised to connect the GSM modem to the serial port of the management modules 0. If the serial port of the management modules 0 fails, connect the GSM modem to the serial port of the management modules 1.

To demonstrate how to configure a GSM modem, the COM1 serial port (baud rate = 115200 bit/s) on the host and the DB9 serial port on the GSM modem (default baud rate = 9600 bit/s) is used as an example.

Procedure

  1. Insert a SIM card into the GSM modem.
  2. Connect GSM modem to the maintenance terminal serial port through a DB9 serial cable.
  3. Put the power cable of the GSM modem into the power supply outlet, then power on the GSM modem.

    If the red indicator blinks, the GSM modem is successfully installed.

  4. Run PuTTY. In the Category navigation tree, choose Session > Logging. The Basic options for your PuTTY session page for configuring the GSM modem is displayed, as shown in Figure A-1.

    Figure A-1  Page for Basic options for your PuTTY session

  5. Click Open.
  6. Run the at command on the COM1-PuTTY, and OK appears in the output if the GSM modem has connected to the host through the serial port. If this is true, go to 9. If running that command responds with nothing, the GSM modem has been disconnected from the serial port. If this is true, go to 7.
  7. Re-log in to the page for configuring the GSM modem, as shown in Figure A-2.

    Figure A-2  Page for configuring the GSM modem

  8. Reset the baud rate of the GSM modem until running the at command responds with OK.

    NOTE:
    • If the baud rate of the GSM modem is not confirmed, reconfigure it to ensure that the baud rate of the GSM modem and that of the serial port are consistent. In this condition, the PuTTY can be used to configure the GSM modem.
    • The baud rate can be configured using the command at+ipr=115200.

  9. Configure other parameters, for example whether to reply automatically.
  10. Click OK to save and exit. To verify the configuration, the following shows the configuration success page.

    at
    OK
    at+ipr=115200
    OK
    ats0=1
    OK
    at&w
    OK
    

  11. Upon successful configuration, connect the GSM modem to the serial port of the storage system for use.

    NOTE:

    For details about configuring the GSM modem, see the corresponding manual supplied with the GSM modem.
