Modifying Alarm Dump Settings (Applicable to V300R003C00/V300R003C10)

Modifying Alarm Dump Settings (Applicable to V300R003C00/V300R003C10)

After you enable the alarm dump function, alarm messages will be dumped automatically to a specific FTP or SFTP server when they exceeds a system-definable threshold.

Prerequisites

  • The alarm dump function has been enabled.
  • The communication is normal between the FTP or SFTP server and the primary controller of the storage system. To improve communication reliability, you are advised to configure the FTP or SFTP server and the primary controller of the storage system on the same LAN and their IP addresses in the same network segment.
    NOTE:
    • The alarm dump function is invalid if the FTP or SFTP server connects to the network port on the secondary controller of the storage system.
    • To check whether a controller is the primary controller, run the show controller general command. If the value of Role is Master, the controller is the primary controller.
  • If alarm information is stored on an FTP server and a firewall is configured on the network, port 21 is enabled.
  • If alarm information is stored on an SFTP server and a firewall is configured on the network, port 22 is enabled.

Context

  • If alarm dump is not configured for the storage system, when the number of generated events reaches 45,000, the alarm named The Space That Stores Event Logs Is To Be Used Up is triggered. When the number of generated events reaches 50,000 (the upper limit), the first 10,000 events are deleted automatically.
  • If alarm dump is configured for the storage system, when the number of generated events reaches 45,000, the alarm named The Space That Stores Event Logs Is To Be Used Up is not triggered. When the number of generated events reaches 50,000 (the upper limit), the first 10,000 events are dumped automatically to the specified FTP server or SFTP server.
NOTE:
To ensure that all events generated by the storage system are retained, it is recommended that you configure alarm dump.

Procedure

  1. Log in to DeviceManager.
  2. Choose Settings > Alarm Settings.
  3. Modify parameters for the alarm dump.
    1. In the navigation tree, choose Alarm Dump.
    2. Modify parameters for the alarm dump. Table 8-3 lists related parameters.

      [Example]

      FTP

      Username

      Name of a user on the server that will be used to store the alarm information.

      [Value range]

      • The value must be unique.
      • It contains 1 to 63 characters.
      • It cannot contain single quotation marks (').

      [Example]

      files

      Password

      Password for logging in to a server.

      [Value range]

      It contains 1 to 63 characters.

      [Example]

      123456

      Server

      IP address of a server.

      [Value range]

      • An IPv4 address has the following requirements:
        • The 32-bit address is evenly divided into four fields. Each 8-bit field is expressed in dotted-decimal.
        • Each field of the IP address cannot be blank and must be an integer.
        • The value of the first field ranges from 1 to 223 (excluding 127).
        • The values of other fields range from 0 to 255.
        • The IP address cannot be a special address such as the broadcast address.
      • An IPv6 address has the following requirements:
        • The 128-bit address is evenly divided into eight fields. Each 16-bit field is expressed in hexadecimal and separated with colons.
        • In each 16-bit field, zeros before integers can be removed. However, at least one digit must be reserved in each field.
        • If the IP address contains a long string of zeros, you can represent the neighboring zeros with double colons (::) in the colon-separated hexadecimal field. Each IP address contains only one double-colons (::). The double-colons (::) can also be used to represent neighboring zeros of the IP address.
        • The IP address cannot be a special address such as network address, loop address, or multicast address.

      [Example]

      192.168.0.1

      fc00::1234

      File Save Path

      Path to a directory for storing dumped performance monitoring data. To enable this parameter, you must set up a path and create a folder under it, and type the name of the folder in File Save Path on the DeviceManager.

      [Example]

      If you set the path to G:\ and create a folder named alarm on the FTP server, type alarm in File Save Path.
