Whole-Device Fault Troubleshooting

Whole-Device Fault Troubleshooting

This section describes how to replace a faulty device and perform configurations on the new device.

Background

If a device encounters a hardware fault due to a natural disaster or accident and cannot be used, the device needs to be replaced by a new one immediately to minimize the impact on services.

For smooth service migration, ensure that the new device has the same system software, configuration, license, and patch files as those on the faulty device before you use the new device. See the following corresponding troubleshooting guide based on whether the faulty device is equipped with storage media and whether the storage media are damaged.

Troubleshooting Guide for the Faulty Device Without Storage Media or with Damaged Storage Media

  1. Log in to the new device through the console interface and configure a management IP address on GE 0/0/0.

    For detailed operations, see Configuring Login Through a Console Port. The management IP address and the terminal used to upload files must be routable.

  2. Configure an FTP local user account and related configurations and enable the FTP server function on the new device.

    Step

    Command

    Precautions

    1

    • Run the aaa command to enter the AAA view.

    • Run the local-user user-name password [ cipher password | irreversible-cipher irreversible-cipher-password ] command to configure a local user account and password.

    -

    2

    Run the local-user username service-type ftp command to configure the local user type.

    -

    3

    Run the local-user user-name ftp-directory directory command to configure an FTP directory for the local user. If the local user logs in to the device using FTP, the user accesses the specified FTP directory.

    4

    Run the local-user user-name level level command to set the local user priority. The priority of the local user must be set to level 3 or higher so that the local user can access the FTP server.

    5

    Run the commit command to commit configurations.

    -

    6

    Run the ftp server enable command in the system view to start the FTP server. By default, the FTP server function is disabled. To determine whether the function is enabled, run the display tcp status command to check whether the port number 21 is monitored by the FTP server.

    7

    Run the commit command to commit configurations.

    -

  3. Use FTP to upload the files needed by an upgrade, such as the system software, configuration, and license files, from a PC or a terminal of another type to the new device.

    NOTE:

    The files needed by an upgrade include the system software, configuration, license, PAF, and patch files, in which the last three files are optional. If the optional files exist in the faulty device, they need to be uploaded.

    Step

    Operation

    Precautions

    1

    Use FTP to upload the files needed by an upgrade, such as the system software, configuration, and license files, from a PC or a terminal of another type to the new device.

    For geographical redundancy, configure the system to periodically save the configuration file to the server so that the system saves the configuration file to the server whenever the configuration file is saved automatically.

    To configure the system to periodically save the configuration file to the server, run the set save-configuration backup-to-server server server-ip [ vpn-instance vpn-instance-name ] transport-type { ftp | sftp } user user-name password password [ path folder ] command in the system view.

    2

    Log in to the new device and run the dir command to check whether the files exist.

    -

    3

    Run the copy source-filename destination-filename command to copy the files to the slave main control board (if any).

    -

    4

    Run the check system-software file-name command to check the checksum of the specified system software. The execution of the command takes about 3–10 minutes.
  4. Specify next-startup files, such as the system software, configuration, and patch files, and restart the device for the upgrade.

    Step

    Operation

    Precautions

    1

    Run the startup system-software system-file [ all | slave-board | slot slot-id ] [ integrity ] command in the user view to specify the next-startup system software file.

    • The all parameter indicates that the next-startup system software file is specified for both main control boards. The slave-board parameter indicates that the next-startup system software file is specified for the slave main control board.
    • If you specify the integrity parameter, the device performs CRC check on the total content of the system software. If you do not specify the integrity parameter, the device performs CRC check only on partial content of the system software, which cannot guarantee the correctness and integrity of system software.

    2

    Run the startup saved-configuration configuration-file command to specify the next-startup configuration file.

    -

    3

    (Optional) Run the startup patch patch-file all command to specify the next-startup patch file.

    Skip this step if no patch files exist on the faulty device.

    4

    (Optional) Run the startup paf { default | patch-file } command to specify the next-startup PAF file.

    Skip this step if no PAF files exist on the faulty device.

    6

    Run the display startup command to check whether the next-startup files are correctly configured.

    -

    7

    Run the reboot [ fast | save diagnostic-information ] command to restart the device.
    • After the reboot save diagnostic-information command is run, the system saves diagnostic information in the root directory of the CF card before the system restarts.

    • After the reboot fast command is run, the system restarts immediately, without prompting you to save configurations. Those configurations that are not saved are lost.

    8

    Perform the following operations after the device is restarted:
    • Run the display version command to check whether the current system version is correct.
    • Run the display configuration configuration-file command to check whether the configuration file is correct.
    • Run the display configuration recover-result command to check the configuration restoration result.
    • Run the display current-configuration command to check the configurations that have taken effect.

    If you check the current configurations immediately after the system is restarted, you are prompted that the system is busy. In this case, wait a while.

  5. Replace the faulty device and install the optical cables connected to the faulty device on the new device.

    Record the slot ID of each board and the mapping between interfaces and optical fibers and remove the faulty device from the cabinet.

    Install the new device that has been configured in the cabinet and install boards and optical fibers according to the record.

  6. Upload the license file of the faulty device to the new device and activate the file.

    NOTE:
    The main control boards' ESNs must be the same as the ESN contained in the GTL license to be activated. To meet customers' requirements in the case of emergency, V800R009C00 and later versions allow the device to borrow the license corresponding to the ESN of another device and use the license for 60 days.

    To activate a license file, run the license active license-file-name command in the user view.

  7. Log in to the new device, obtain the ESN of the master or slave main control board, notify Huawei of the ESN, and apply for a new license file.

    To obtain the ESN of the master or slave main control board, run the display esn command.

  8. Upload the new license file to the new device and activate the file.

    After receiving the new license file from Huawei, perform the following operations.

    Step

    Operation

    Precautions

    1

    Upload the new license file. For details, see steps 1 to 3.

    -

    2

    Run the license revoke command in the user view to revoke the original license file.

    -

    3

    Run the license active license-file-name command to activate the new license file.

Troubleshooting Guide for the Faulty Device with Undamaged Storage Media

  1. Power off the faulty device, remove its storage media, and install the storage media on the new device.

  2. Power on the new device.

    Perform the following operations after the device is started:

    NOTE:

    When a CF card on a replaced device is installed on a new device and the new device starts, the new device searches the CF card for the system software package that has the same name as that used in the previous startup of the new device. If the system software package is found, the new device starts using this package. If the software package is not found, the new device searches for the system software package that has the same name as that used in the startup before the previous startup. If the software package is found, the new device starts using this package. If the software package is not found, the new device searches the CF card for the system software package that has the latest modification time, and then starts using this software package.

    Therefore, storing only one system software package in the CF is recommended, and ensure that this package applies to the new device.

    • Run the display version command to check whether the current system version is correct.
    • Run the display configuration configuration-file command to check whether the configuration file is correct.
      NOTE:

      If more than one configuration file exists in the storage media, the new device may restart using an unexpected configuration file. In this case, perform the following operations.

      Step

      Operation
