How to Lock Cluster Management Interfaces (BUI)
How to Lock Cluster Management Interfaces (BUI)
Use the following procedure to lock the management interfaces on clustered controllers after
initial configuration.
A private (locked) management interface provides BUI and CLI access to a controller
regardless of whether the controller is in the active or passive state. Because all non-private
interfaces are taken over by the active controller after a failover, a passive controller must have
a private management interface to remain accessible through its BUI and CLI.
Caution - Failure to configure locked management interfaces on clustered controllers may lead
to longer than necessary fault diagnosis and resolution times.
Before You Begin
In some cases, this may require installation of an additional network interface card on each
controller in a cluster configuration.
