Oracle Cluster Verification Utility

Oracle provides Cluster node verification prior to installation. It is very helpful for Oracle RAC pre-installation to check the nodes meeting the system minimum requirement, the network interfaces availability, the patches update and etc.

Oracle Grid pre-installation
To verify whether your system meets all of the criteria for an Oracle Clusterware installation:
Window:
cluvfy stage -pre crsinst -n node1,node2,node3
Unix:
runcluvfy.sh stage -pre crsinst -n node1,node2,node3

After you have completed phase one, verify that Oracle Clusterware is functioning properly before proceeding with phase two of your Oracle RAC installation:
Window:
cluvfy stage -post crsinst -n node1,node2,node3 -v
Unix:
runcluvfy.sh stage -post crsinst -n node1,node2,node3 -v

To verify whether your system meets all of the criteria for an Oracle RAC installation:
Window:
cluvfy stage -pre dbinst -n node1,node2,node3 -v 
Unix:


Oracle Database pre-installation
To verify whether your system meets all of the criteria for creating a database or for making a database configuration change:
Window:
cluvfy stage -pre dbcfg -n -n node1,node2,node3 -d oracle_home -v
Unix:
runcluvfy.sh stage -pre dbcfg -n -n node1,node2,node3 -d oracle_home -v

Refer to Cluster Verification Utility Reference for more detail explanation.

runcluvfy.sh stage -pre dbinst -n node1,node2,node3 -v

  1. Take note the cluster nodes ssh trust is mandatory for the CVU to execute properly with oracle user. Below is the OTN forum discussing how the setup should be done. https://forums.oracle.com/forums/thread.jspa?threadID=549286
