To provide CVU a list of all of the nodes of a cluster, enter -n all. CVU attempts to obtain the node list in the following order:
If vendor clusterware is available, then CVU selects all of the configured nodes from the vendor clusterware using the lsnodes utility.
If Oracle Clusterware is installed, then CVU selects all of the configured nodes from Oracle Clusterware using the olsnodes utility.
If neither the vendor clusterware nor Oracle Clusterware is installed, then CVU searches for a value for the CV_NODE_ALL key in the configuration file.
If vendor clusterware and Oracle Clusterware are not installed and no key named CV_NODE_ALL exists in the configuration file, then CVU searches for a value for the CV_NODE_ALL environmental variable. If you have not set this variable, then CVU reports an error.
To provide a partial node list, you can set an environmental variable and use it in the CVU command. For example, on Linux or UNIX systems you can enter:
setenv MYNODES node1,node3,node5 cluvfy comp nodecon -n $MYNODES [-verbose]
