Locking a Cluster Management Interface (CLI)

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.

Go to configuration cluster resources and enter the show command.
Select the management interface, prefaced with net/.

Lock the interface by setting the type to private.

hostname:configuration cluster resources net/vnic1> set type=private
                         type = private (uncommitted)
hostname:configuration cluster resources net/vnic1> commit

Next Steps

Repeat this procedure on the second controller.
