19.5. Adding a node to a cluster with multiple links
When adding a node to a cluster with multiple links, you must specify addresses for all links.
The following example adds the node rh80-node3 to a cluster, specifying IP address 192.168.122.203 for the first link and 192.168.123.203 as the second link.
# pcs cluster node add rh80-node3 addr=192.168.122.203 addr=192.168.123.203
