Use the cluvfy stage -post cfs stage verification command to perform the appropriate checks on the specified nodes after setting up OCFS2.

Use the cluvfy stage -pre crsinstcommand with either the -file, -n, -flex, or -upgrade parameters to check the specified nodes before installing or upgrading Oracle Clusterware.

Use the cluvfy stage -post crsinstcommand to check the specified nodes after installing Oracle Clusterware

cluvfy stage -pre dbcfg

Use the cluvfy stage -pre dbcfg command to check the specified nodes before configuring an Oracle RAC database to verify whether your system meets all of the criteria for creating a database or for making a database configuration change.

cluvfy stage -pre dbinst

Use the cluvfy stage -pre dbinstcommand to check the specified nodes before installing or creating an Oracle RAC database to verify that your system meets all of the criteria for installing or creating an Oracle RAC database

cluvfy stage -post hwos

Use the cluvfy stage -post hwos stage verification command to perform network and storage verifications on the specified nodes in the cluster before installing Oracle software. This command also checks for supported storage types and checks each one for sharing.

cluvfy stage [-pre | -post] nodeadd

Use the cluvfy stage -pre nodeaddcommand to verify the specified nodes are configured correctly before adding them to your existing cluster, and to verify the integrity of the cluster before you add the nodes.

This command verifies that the system configuration, such as the operating system version, software patches, packages, and kernel parameters, for the nodes that you want to add, is compatible with the existing cluster nodes, and that the clusterware is successfully operating on the existing nodes. Run this command on any node of the existing cluster.

Use the cluvfy stage -post nodeaddcommand to verify that the specified nodes have been successfully added to the cluster at the network, shared storage, and clusterware levels

cluvfy stage -post nodedel

Use the cluvfy stage -post nodedelcommand to verify that specific nodes have been successfully deleted from a cluster. Typically, this command verifies that the node-specific interface configuration details have been removed, the nodes are no longer a part of cluster configuration, and proper Oracle ASM cleanup has been performed.

cluvfy comp nodecon

Use the cluvfy comp nodecon component verification command to check the connectivity among the nodes specified in the node list. If you provide an interface list, then CVU checks the connectivity using only the specified interfaces.

cluvfy comp nodeapp

Use the component cluvfy comp nodeappcommand to check for the existence of node applications, namely VIP, NETWORK, and ONS, on all of the specified nodes.

cluvfy comp healthcheck

Use the cluvfy comp healthcheckcomponent verification command to check your Oracle Clusterware and Oracle Database installations for their compliance with mandatory requirements and best practices guidelines, and to ensure that they are functioning properly

Use the cluvfy comp ha component verification command to check the integrity of Oracle Restart on the local node.

cluvfy comp gpnp

Use the cluvfy comp gpnp component verification command to check the integrity of Grid Plug and Play on a list of nodes in a cluster.

cluvfy comp dhcp

Use the cluvfy comp dhcp component verification command to verify that the DHCP server exists on the network, and that it can provide a required number of IP addresses. The required number of IP addresses is calculated, as follows:

• Regardless of the size of the cluster, there must be three scan VIPs
• One node VIP for each node you specify with the -n option
• One application VIP for each application VIP resource you specify with the -vipresnameoption
