Cluster Verification Utility (aka CVU, command runcluvfy.sh or cluvfy) does very good checking on the network and name resolution setup, but it may not capture all issues. If the network and name resolution is not setup properly before installation, it is likely the installation will fail; if network or name resolution is malfunctioning, likely the clusterware and/or RAC will have issues. The goal of this note is to provide a list of things to verify regarding the network and name resolution setup for Grid Infrastructure (clusterware) and RAC.
