Scenario: What happens after the active MVS Session Manager stops responding
If the active MVS Session Manager stops responding, the response of the MVS Console depends on the health of the standby MVS Session Manager. If the standby MVS Session Manager is healthy, the MVS Console promotes it to be the active MVS Session Manager.
The following scenario assumes that the MVS Console is available.
1.The MVS Console determines that the active MVS Session Manager stopped responding, demotes the active MVS Session Manager, and promotes the standby MVS Session Manager to be the active instance.
2.The active MVS Session Manager connects to the active BlackBerry® Enterprise Server.
3.The active MVS Session Manager registers the BlackBerry devices with the PBX.
4.An error message appears on the MVS Console to indicate that a MVS Session Manager is unhealthy.
You must resolve any issues with the unhealthy MVS Session Manager before the MVS Console can promote it to be the active instance again.
