Explanation:
$ cluvfy stage -post nodeadd -n node3 [-verbose]
Use the cluvfy comp peer component verification command to check the compatibility and properties of the specified nodes against a reference node. You can check compatibility for non-default user group names and for different releases of the Oracle software. This command compares physical attributes, such as memory and swap space, as well as user and group values, kernel settings, and installed operating system packages.
Syntax
cluvfy comp peer -n node_list [-refnode node] [-r {10gR1 | 10gR2 | 11gR1 | 11gR2}] [-orainv orainventory_group][-osdba osdba_group] [-verbose] Usage Notes
Peer comparison with the -refnode option compares the system properties of other nodes against the reference node. If the value does not match (the value is not equal to reference node value), then CVU flags that comparison as a deviation from the reference node. If a group or user does not exist on reference node as well as on the other node, CVU reports this comparison as 'passed' because there is no deviation from the reference node. Similarly, CVU reports as 'failed' a comparison with a node that has more total memory than the reference node.
$ cluvfy stage -pre nodeadd -n node3 [-fixup [-fixupdir fixup_dir]] [-verbose] You can specify the -fixup option and a directory into which CVU prints instructions to fix the cluster or node if the verification fails.
