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.
  1. From the Configuration menu, select Cluster.
  2. Choose the management interface from the Resource list.
  3. Click the padlock icon to lock the management interface to this controller.

    The interface displays a locked icon image showing the lock icon .

  4. Click APPLY in the upper-right corner of the page.

Next Steps

Repeat this procedure on the second controller.
