Replacing the Active Server with Another Server

If the Deep Discovery Director server is unresponsive or cannot be restored, it can be replaced by another server.

The following table lists requirements that need to be fulfilled by the replacement server. For details, see the Deep Discovery Director Administrator's Guide.

Table 1. Replacement Server Requirements

Requirement

Description

Host machine hardware

Must be the same as active server

Host machine software

Must be the same as active server

Deep Discovery Director deployment type

Must be the same as active server

Deep Discovery Director version and build

Must be the same as active server

  1. Back up the configuration settings and database of the active server.
    1. On the management console of the active server, go to Administration > System Maintenance > Back Up.
    2. Under Configuration Settings and Database Backup, click Export.

      The active server exports a backup file with the configuration settings and database. For details, see Back Up.

    3. Download and save the backup file.
  2. Install Deep Discovery Director on the replacement server.

    For details, see the Deep Discovery Director Administrator's Guide.

  3. Configure temporary network addresses for the replacement server.

    For details, see the Deep Discovery Director Administrator's Guide.

    Important:

    Verify that the temporary network addresses are different from the network addresses of the active server to avoid IP addressing conflicts.

  4. Log on to the management console of the replacement server.
  5. Restore the configuration settings and database on the replacement server.
    1. On the management console of the replacement server, go to Administration > System Maintenance > Restore.
    2. Click Select File... and select the backup file.
    3. Click Upload.

      The backup file is uploaded, and Deep Discovery Director displays information about the backup file.

    4. Click Restore.

      Deep Discovery Director displays a confirmation message.

    5. Click OK.

      Deep Discovery Director restores configuration settings and database from the backup file, and then restarts the server.

  6. Restore the repository.
    • Consolidated mode: Re-upload all previously uploaded update, upgrade, and Virtual Analyzer image files to the repository.

      Important:

      Update, upgrade, and Virtual Analyzer image files are not included in the backup file and are not restored automatically. Appliances cannot download and execute plans if the files are not re-uploaded to the repository.

    • Distributed mode: The Management Server automatically receives the list of available update, upgrade, and Virtual Analyzer image files from the Central Repository server.

  7. Power off the active server.
    1. On the management console of the active server, go to Administration > System Maintenance > Power Off / Restart.
    2. Click Power Off.

      The active server stops all services and gracefully shuts down.

      Warning:

      The replacement server will be configured to use the network addresses of the active server. Leaving the active server powered on will cause IP addressing conflicts.

  8. Configure the replacement server to use the network addresses of the active server. For details, see Network.
  9. Activate Deep Discovery Director. For details, see License.

    The replacement server is now ready to resume operation as the new active server.
