How Do I Install an NSM Server in High Availability Mode?
Solution:

Network and Security Manager (formerly known as NetScreen-Security Manager) enables you to install the management system and configure it for High Availability (HA). This configuration option involves installing two management systems:
 

  • A Primary server that runs on a server machine in active mode
  • A Secondary server that runs on a different server machine in standby mode

 
If for any reason the Primary server becomes unavailable, then the Secondary server takes over as the active management system.

The HA installation and configuration has two main options for installing the NetScreen-Security Manager in an HA configuration:
 

  • Installing the Management System - Typical Configuration With HA involves installing and configuring the management system in an HA cluster on two server machines, the Primary management system with the Device server and GUI server on the same machine, and a Secondary management system with the Device server and GUI server together on another machine.
  • Installing the Management System - Extended Configuration With HA involves installing and configuring the management system in an HA cluster on four server machines, the Primary management system with the Device server and GUI server on separate machines and a Secondary management system with the Device server and GUI server on separate machines.

 
You can also install and configure HA clusters in either scenario with access to a shared disk. For further information on system requirements, data replication and more, go to the Network and Security Manager Documentation.

noteThe Primary and the Secondary servers must be on the same WAN for the HA configuration. They must be able to reach each other so proper fail-over can occur.  Also the devices must be able to reach both Device Servers.

To install an NSM server in High Availability mode, perform the following steps:

Install and configure in HA mode via the Command Line Interface (CLI), For more information go to KB4517 - Installing and Configuring HA on Juniper Networks NSM via the CLI.

 Install and configure HA on the Primary NSM server via the GUI. For more information, go to KB4518 - Installing and Configuring HA on the Primary NSM Server via the GUI.

 Install and configure HA on the Secondary NSM server via the GUI. For more information, go to KB4519 - Installing and Configuring HA on the Secondary NSM Server via the GUI.
