After initial configuration, clustered controllers are in an active-active state. When a failover occurs, an active controller takes over all non-private interfaces, and the peer controller becomes passive and inaccessible by its BUI and CLI. To maintain access to a controller regardless of its state, lock its management interface to make it private. The following procedure locks the management interface on each clustered controller.
Caution - Failure to configure locked management interfaces on clustered controllers may lead to longer than necessary fault diagnosis and resolution times. |
