That error usually means there is a network cable disconnected on a NIC card that has been configured as part of a bond or as a standalone interface. Or there is a problem with the switch port.
Sometimes it is just because that NIC card is part of a bond, but you are not using it. Look at the output from the command "network --show" on from the DR command line interface, and try to determine if the the affected interface is being used. It can be safely removed from the bond configuration if it is not needed.
