1. Run add node command from node which is in the cluster

grid@xxx001cc01vm02():/> /u01/app/18.3.0.0/grid/addnode/addnode.sh -silent "CLUSTER_NEW_NODES={xxx001cc01vm01}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={xxx001cc01vm01-vip}" "CLUSTER_NEW_NODE_ROLES={hub}"

You might receive following message: @ 49%

SEVERE:Remote 'AttachHome' failed on nodes: 'xxx001cc01vm01'.

Then execute

/u01/app/18.3.0.0/grid/oui/bin/runInstaller -attachHome -noClusterEnabled ORACLE_HOME=/u01/app/18.3.0.0/grid ORACLE_HOME_NAME=OraGI18Home1 "CLUSTER_NODES={xxx001cc01vm02,xxx001cc01vm03,xxx001cc01vm01}" CRS=true  INVENTORY_LOCATION=/u01/app/oraInventory  LOCAL_NODE=xxx001cc01vm01

You might receive following message:  @ 90%
