Remove high availability

In a standalone installation, BlackBerry MVS users are served by one MVS Session Manager and one MVS BlackBerry Enterprise Server Connector. When you associate two BlackBerry MVS Server instances to form a high availability pair, the MVS Session Manager instances and MVS BlackBerry Enterprise Server Connector instances operate in an active-standby mode. All users are served by the active MVS Session Manager and the active MVS BlackBerry Enterprise Server Connector.

There are two ways you can remove high availability:
  • You can remove the configuration entirely from the BlackBerry MVS configuration
  • You can suspend high availability by taking one of the BlackBerry MVS Server instances offline

When you remove high availability, all record of the high availability association between the two BlackBerry MVS Server instances is deleted from the BlackBerry MVS configuration . Both MVS Session Manager instances and both MVS BlackBerry Enterprise Server Connector instances return to an active state and both BlackBerry MVS Server instances are available. However, all users are allocated to only one of the BlackBerry MVS Server instances. To remove high availability, you use the MVS Console and click the Remove high availability button associated with one of the BlackBerry MVS Server instances; all users are allocated to the other BlackBerry MVS Server.

When you suspend high availability, the high availability configuration is preserved but one BlackBerry MVS Server is offline so there is only one MVS Session Manager and one MVS BlackBerry Enterprise Server Connector serving users. High availability is restored when the offline BlackBerry MVS Server is brought back online. Suspending high availability is sufficient for upgrade and maintenance activities.
