To configure failover for roles on your system, you must select secondary servers to be on standby in case the primary server hosting the role becomes unavailable.

Before you begin

For roles that require a database (with the exception of the Archiver role), the database must be hosted on a different computer than any of the servers assigned to the role. All servers assigned to the role must be able to connect to the server managing the role database.
IMPORTANT: All servers assigned to the same role must be running the same version of Security Center.

What you should know

To set up failover for an Archiver role, see Archiver failover.

Procedure

  1. From the Config Tool home page, open the System task, and click the Roles view.
  2. Select the role you want to configure failover for, and then click the Resources tab where the role’s primary server is listed
  3. Under the Servers list, click Add an item ().
    A dialog box opens, listing all remaining servers on your system that are not yet assigned to this role.
  4. Select the server that you want to add as a secondary server and click Add.
    The secondary server is added below the primary server. The green LED indicates which server is hosting the role.
    NOTE: The servers are listed in the order that they are picked if a failover occurs. When the primary server fails, the role automatically switches to the next server on the list.
  5. To change the priority of a server, select it from the list, and click the or buttons to move it up or down the list.
  6. If you want the primary server to retake control after it is restored from a failover, select the Force execution on highest priority server option.
    To minimize system disruption, the role remains on the secondary server after a failover occurs, by default.
  7. Click Apply.
