Manually Failing Over the Network Management Services to the Standby Site

 

You may need to fail over the network management services to the standby site even when the active site is fully operational. You execute the jmp-dr manualFailover command at the standby site to fail over the network management services to the standby site. When the failover is complete, the standby site becomes the new active site.

Note

We recommend that you check the status of the disaster recovery configuration before and after executing the jmp-dr manualFailover command. To do so, execute the jmp-dr health command at both sites.

To manually fail over the network management services to the standby site:

  1. Log in to the CLI of the Junos Space node at the standby site on which the VIP or the eth0:0 interface is configured.

    The Junos Space Settings Menu is displayed.

  2. Enter 6 (if you are using a hardware appliance) or 7 (if you are using a virtual appliance) at the Junos Space Settings Menu prompt to run shell commands.

    The following is a sample output from a virtual appliance:

    You are prompted to enter the administrator password.

  3. Enter the administrator password.
  4. Type jmp-dr manualFailover at the shell prompt and press Enter.
  5. Enter Yes.

    The following is a sample output:

The standby site becomes the new active site.

Note

If you have made any NAT-related updates in any of the disaster recovery sites, after a manual failover, run the following commands to ensure that NAT devices work seamlessly with the new active site:

  1. Move the backup file from /var/cache/jmp-geo/config/diff.properties_backup to /var/cache/jmp-geo/config/diff.properties.

  2. Run the following command on the VIP node to update the changed standby cluster device management, NAT, and IP configuration on the current active site:
