To disable unused interfaces, first determine which interfaces are being used, by physically examining the network ports, and / or check the output of "network --show" to see which interfaces are currently assigned to the bond.
You will need access to the command line interface, which can be accessed using an ssh client like putty to the DR appliance's IP address.
For any interfaces that are not assigned to any bond and are not used, they can be disabled by running the command "network --disable --nwif ethX" where "ethX" is the interface that you want to disable. For example, to disable eth2 and eth3, run the following commands from the command line:
network --disable --nwif eth2
network --disable --nwif eth3
In order for the changes to take effect, you will need to restart the network. This should be done when there are no backup jobs running to the DR:
network --restart
If the interfaces are still showing as alerts in the Health dashboard, please refresh the page or clear the browser cache.
