Managing Alarm Dump

Managing Alarm Dump

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

Configuring an FTP Server

FTP servers store alarm files dumped from storage systems. You are required to re-configure an FTP server due to services change. You can install and configure a wide range of FTP servers.

Prerequisites
  • The FTP server software installation package is ready.
  • The IP address to be configured can properly communicate with the storage system.
  • This section describes how to configure an Xlight FTP server. For details about how configure other FTP servers, see the related configuration documentation.
Procedure
  1. Start the Xlight FTP server software.

    The Xlight FTP Server page is displayed.

  2. Configure a virtual server.

    1. On the Xlight FTP Server page, click .

      The New Virtual Server dialog box is displayed.

    2. In the New Virtual Server dialog box, set IP Address, Port, and Protocol to the local IP address, 21, and FTP, respectively.
    3. Click OK.

      The added virtual server is displayed in the Xlight FTP Server page that is displayed.

  3. Start the virtual server.

    Select the added virtual server and click to start the server.

    NOTE:

    You can select the added virtual server, right-click, and choose Start Server to start the server.

  4. Add a user.

    1. On the Xlight FTP Server page, click .

      The user list is displayed.

    2. Click .

      The adding users dialog box is displayed.

    3. In the dialog box, enter Username and Password and set Home Directory.
    4. Click OK.

      The user is added, and user information is displayed on the user page.

  5. Set virtual directory permissions.

    1. In the user list, select the added user and click .

      The user name page is displayed.

    2. On the navigation bar on the left, click .

      The user directory management page is displayed.

    3. Select the access directory of the added user and click .

      The Virtual Directory dialog box is displayed.

    4. In the Permission area, set permissions.
    5. Click OK.

      Virtual directory permissions are configured.

Modifying Alarm Dump Settings

This section describes how to modify alarm dump settings. You can modify the alarm dump settings based on service requirements to ensure the integrity of alarm information recorded by a storage system.

Prerequisites
  • The alarm dump function has been enabled.
  • If alarm information is stored on an FTP server, communication must be normal between the server and the storage system. To improve communication reliability, you are advised to configure them both on the same LAN and their IP addresses in the same network segment.
  • If alarm information is stored on an SFTP server, communication must be normal between the server and the storage system. To improve communication reliability, you are advised to configure them both on the same LAN and their IP addresses in the same network segment.
  • 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.
  • Before configuring a domain name for the server, ensure that the DNS server can communicate normally with the storage array or third-party server.
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:
    • For V500R007C20 and earlier versions, 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.
    • For V500R007C30 and later, 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 login and logout events reaches 20,000 (the upper limit), the first 10,000 events are dumped automatically to the specified FTP server or SFTP server. 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.
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 5-23 lists related parameters.
