Locking a Cluster Management Interface (BUI)
After initial configuration, clustered controllers are in an active-active state. When a failover occurs, the 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 the management interface private. Use this procedure to lock the management interface of each controller in a cluster.
Note:
Failure to configure locked management interfaces on clustered controllers might result in longer fault diagnosis and resolution times.Next Steps
Repeat this procedure on the second controller.
