Locking Cluster Management Interfaces (BUI)
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. |
- In the BUI of the first controller, navigate to Configuration > Cluster.
- In the BUI of the second controller, navigate to Configuration > Cluster.
- From the BUI of the first controller, choose the management interface for the first controller from the Resource list.
-
Click the padlock icon
to lock the management interface to this
controller.
The interface displays a locked icon
next to its name in the Resource list. - From the BUI of the second controller, choose the management interface for the second controller from the Resource list.
