MiVB Cluster Behavior and User Management Limitations

Mitel Administration (MA) can manage users in MiVoice Business (MiVB) clusters, but only under certain conditions. Whether a user can be managed depends on which MiVB system is connected and where the user is hosted.

Supported User Scenarios

User Setup Supported? Explanation

A (Primary Host A)

Yes The user is hosted on the same MiVB that MA is connected to.

A-B (Primary A, Secondary B)

Yes The user is hosted on Primary A, and changes sync to Secondary B.

B-A (Primary B, Secondary A)

Partially The user is hosted on B, but MA is connected to A. Some actions may work, but full management is not guaranteed.

B (Primary Host B only)

No The user is hosted on B, and MA is not connected to it. The system shows “MiVB not reachable.”
Note: MA always assumes the connected MiVB is the user’s Primary. It does not switch to the Secondary or Resilient controller.

Template Limitations

  • If a user template refers to a MiVB that is not connected to MA, it may import successfully but cannot be used to create users.
  • In newer versions, MA may block such templates during import to avoid errors.

Error Message Behavior

If you try to manage a user whose Primary MiVB is not the one MA is connected to, you may see this message: "MiVB not reachable".

This means MA cannot reach the user’s actual Primary MiVB, so the user cannot be managed.

CLD-Based Deployments

In CloudLink Daemon (CLD) environments, you can explicitly assign which MiVB controls a user. This makes it easier to manage users correctly, compared to older CloudLink Gateway (CLGW) setups.
