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.
Table A-15 cluvfy comp nodecon Command Parameters
| Parameter | Description |
|---|---|
-n node_list |
The comma-delimited list of nondomain qualified node names on which to conduct the verification. |
-networks network_list |
The forward slash (/)-delimited list of networks on which to conduct the verification. |
-i interface_list |
The comma-delimited list of interface names. If you do not specify this option, then CVU discovers the available interfaces and checks connectivity using each of them. |
-verbose |
CVU prints detailed output. |
You can run this command in verbose mode to identify the mappings between the interfaces, IP addresses, and subnets.
On Solaris platforms, this command skips testing IP addresses that are marked as deprecated.
Use the nodecon command without the -networks option and with -n set to all to use CVU to:
Discover all of the network interfaces that are available on the cluster nodes
Review the interfaces' corresponding IP addresses and subnets
Obtain the list of interfaces that are suitable for use as VIPs and the list of interfaces to private interconnects
Verify the connectivity between all of the nodes through those interfaces
Example 1: Verifying the connectivity between nodes through specific network interfaces:
You can verify the connectivity between the nodes node1 and node3 through interface eth0 by running the following command:
cluvfy comp nodecon -n node1/node3 –networks eth0 -verbose
Example 2: Discovering all available network interfaces and verifying the connectivity between the nodes in the cluster through those network interfaces:
Use the following command to discover all of the network interfaces that are available on the cluster nodes. CVU then reviews the interfaces' corresponding IP addresses and subnets. Using this information, CVU obtains a list of interfaces that are suitable for use as VIPs and a list of interfaces to private interconnects. Finally, CVU verifies the connectivity between all of the nodes in the cluster through those interfaces.
cluvfy comp nodecon -n all -verbose
