Bonding management network ports for new nodes

You need to refer to the following procedure for bonding management network ports only when the physical switch connected to the management network has LACP enabled. Otherwise, skip this section.

1. Log in to the ACOS system of the nodes to be added using the default root account.

2. Run the cd /etc/sysconfig/network-scripts/ command to navigate to the port configuration file directory.

3. Run the ip a command to view the port information of all NICs, and then run the ethtool <port> command to view the speed of each NIC to determine which port is used for the management network, where <port> represents the actual name of the port.

   • When the management network and storage network are deployed on different virtual distributed switches, the port whose Speed is 1000 Mb/s or higher can be used for the management network.
   • When the management network and storage network are deployed on one virtual distributed switch, the port whose Speed is 10000 Mb/s or higher can be shared by both the management network and storage network.

4. In the directory of the port configuration file, run the following command to bond the ports used for the management network into a single port named pre_bond, and generate the ifcfg-pre_bond configuration file for the port.

   network-preconfig create-lacp --nics <nics>

   <nics> indicates the names of the ports to be bound. The port names must be separated by spaces and the names must be enclosed in quotation marks ("). For example, when you need to bind the ports eth0 and eth1, run network-preconfig create-lacp --nics "eth0 eth1".

   When the following information is displayed, the pre_bond port has been created and the management network ports have been successfully bonded.
