Configuring Upgrade of Key Management Servers

This section describes how to upgrade the software version of the key management server.

Prerequisites
  • The system key of the current key management server has been exported to the two smart cards before an upgrade.
  • The configuration information of the key management server to be upgraded has been manually backed up to the NFS server before the upgrade.
  • An FTP server has been set up and it can communicate properly with the key management servers before the upgrade.
  • A patch package of the key management server has been prepared and decompressed to the directory of the FTP server before the upgrade.
  • Two key management servers in the cluster need to be upgraded to the same version.
Procedure
  1. Enable the maintenance mode of key management servers.
  2. Log in to the key management server management interface through the serial port as user admin.
  3. Select Update and press Enter.

    The System Upgrade page is displayed, as shown in Figure 3-92.

  4. Set upgrade parameters.

    Set Protocol and Port to FTP and 21 respectively, and set Server and Path to the IP address of the FTP server and the path saving the upgrade file on the NTP server. If Save as defaults is selected, the system automatically saves the FTP server information. During the next upgrade, the system automatically set it to the saved configuration. In addition, set File, User, and Password to the name of the upgrade file as well as the user name and password for logging in to the FTP server. After the configuration, select OK and press Enter.

    NOTE:

    After the upgrade succeeds, the key management server automatically restarts.

  5. Verify the upgrade.

    1. Log in to the web interface of the key management server that is upgraded and restarted as an administrator user.
    2. Click the Summary tab and check whether Software version is the same as the target version, as shown in Figure 3-93.
