80001

Minor

Communications Alarm

Parameters

Name

Meaning

Server address

Internet Protocol (IP) address of the active server of the product.

Product name

The product of the source data. It is eSight.

Impact on the System

The automatic backup fails and no backup data is generated for recovery.

Possible Causes

  • The connection between the eSight and the database is abnormal.
  • The network of the server where the backup path is located is abnormal.
  • The backup data volume is huge (more than 1 TB), causing backup timeout.
  • The metadata (information about data organization, data domain, and their relationship) of the database is changed during backup.

Procedure

  1. In the current alarm list, check the location information of the alarm for the product on which the backup fails.

    1. In the alarm list of the Current Alarm page, click the alarm name to open the Alarm Details dialog box.
    2. In Location Info of the Alarm Detail dialog box, view and record the values of Product name, and Server address.

  2. Contact the administrator to check whether the connection between the database and the product queried in Step 1 is normal.

    • If yes, go to Step 3.
    • If no, contact the database administrator to resolve the database connection problem, and go to Step8.

  3. Check whether the database backup path is on the local server.

    1. On the maintenance tool, choose Backup and Restoration > Backup Policy Setting from the main menu.
    2. In Backup Path of the Backup Policy Settingpage, check whether the database backup path is on the local server.
      • If yes, go to Step5.
      • If no, record the IP address of the remote server where the backup path is located, and go to Step 4.

  4. Check whether the connection of the remote server where the backup path is located is normal.

    1. On the maintenance tool, choose System > Server Management from the main menu.
    2. On the Server Management page, check whether Connection Status of the remote server is Online.
      • If yes, go to Step5.
      • If no, contact the device maintenance engineer to resolve the network connection problem, and go to Step8.

  5. Check whether the backup data volume is huge (more than 1 TB) and causes backup timeout.

    1. On the maintenance tool, choose System > Database Information from the main menu.
    2. On the Database Information page, check whether the data size of all databases of Product name queried in Step 1 exceeds 1 TB (1024 GB).

      Data size of a database = total data space of the database - available data space of the database

  6. Dump the database data to ensure that the source data is within 1 TB, and go to Step 8. For details on how to dump the database data, see Setting Data Overflow Dump.
  7. Collect the information about alarm handling, and contact the technical support personnel.
  8. Back up the data immediately. For details, see Related Information.

Clearing

Manually clear the alarm on the eSight. For details about how to manually clear an alarm, see eSight Operation Guide Alarm Management > Handling Alarm Records.

Related Information

The procedure for immediately backing up the data is as follows:

  1. Choose Backup and Restoration > Backup Policy Setting from the main menu.
  1. Select Enable periodic backup and set Backup start time and Backup period.

    You are advised to set the backup period to Days. If Backup period is set to Months, the value of Backup start time cannot be 29, 30, or 31.

    NOTE:

    To avoid exceptions during database backup, the scheduled backup time must be different from the alarm dump time, you are advised to back up the database in peak-off hours.

  2. Click on the left of Custom Backup Directoty to set a user-defined backup folder.

    In the list of user-defined backup folders, click in the Operation column. In the Modify Custom Backup Directoty dialog box, add desired folders and click OK.

    NOTE:
    • This step is optional.

      If a backup folder is not configured, the system backs up only default files (to the path that will be set in next step) according to system configuration.

      If a backup folder is configured, the system backs up the files in the folder and the default files that require backup.

    • The backup folder must be an existing one in the product directory, for example, a folder in eSight installation directory/AppBase.
    • The directory path cannot exceed 255 characters, and a maximum of 255 directories are supported.
    • If the backup folders are the same, only one is saved. If a folder include other folders, only the parent folder is saved.

  3. (Optional) Click on the left of Encryption settings and set the ciphertext password of the backup package.

    The backup package with a ciphertext password prevents data from leaking or being tampered with.

  4. Set the backup path and number of backup files.

    • Backing up to the local server
      1. Select Backup to local server.
      2. In the Local server backup path list, click in the Operation column and set the path for storing backup files in the Modify Backup Directory dialog box.
        NOTE:
        • Changing the backup up frequently is not recommended. Otherwise, early backup packages may be lost.
        • It is advisable to create a directory as a backup directory to avoid the service impacts caused due to backup and restoration.
      3. Set Number of backup files.
      4. Click Apply.
      5. In the Confirm dialog box, click Yes.

        On the Backup Policy Setting page, if Backup policy set successfully is displayed in the lower part, the backup policy is set successfully.

    • Backing up to a remote server
      1. Select Backup to remote server.
      2. Set Server IP address, Connection type and port number, User name, Password, and Remote server backup path.
        • Connection type and port number: Three connection types are available: FTP (File Transfer Protocol), SFTP (Secure File Transfer Protocol), FTPS (File Transfer Protocol over SSL), and SFTP + KEY. To ensure file transfer security, using SFTP and FTPS is recommended.

          SFTP + KEY requires mutual key trust between the primary server and remote server. The following uses the SFTP service of the Linux operating system as an example to describe how to configure mutual trust through SFTP and KEY. For details, see Backup and Restoration in eSight Maintenance Guide.

          Configure key trust between the primary server and remote server as follows:
          1. The default key name is id_ftp_rsa.
            NOTE:

            Private key files are in OpenSSH format, but not the PuTTY private key (PPK) format.

          2. Private keys are stored in the .ssh folder in the home directory of the maintenance tool startup user. If this folder does not exist, create it. For example, if the administrator user starts the maintenance tool on Windows and the home directory of the administrator user is C:\Users\Administrator, the private key is stored in C:\Users\Administrator\.ssh. If ossuser starts the maintenance tool on Linux and the home directory of ossuser is /ossuser, the private key is stored in /ossuser/.ssh.
          3. In an HA system, you need to place the same private key on the secondary server.

          The default port number for the SFTP, FTP, and FTPS protocles are 22, 21, and 990, respectively. You must configure certificates for the client before using the FTPS protocol. For details, see Backup and Restoration in eSight Maintenance Guide.

        • User name: user name mapping to the connection protocol.
        • Remote server backup path: Relative path to the shared directory on the remote server.

          The default backup path of the remote server is the home directory of the user who connects to the remote server.

          For example, assume that the user for connecting to the remote server is ossuser and that the home directory of the user is C:/ossuser on Windows. If a user enters AAA, the files are saved in C:/ossuser/AAA. On the Linux, the user is /ossuser. If a user enters AAA, the files are saved in /ossuser/AAA.

      3. Optional: Click Verify Validity. The parameters are successfully set if Verification succeeded is displayed. If any parameters fail to be set, set the parameters again.
      4. Set Number of backup files.
      5. Click Apply.
      6. In the Confirm dialog box, click Yes.

        The backup policy is successfully set if Backup policy set successfully is displayed.
