Step 6. Verify the node definitions

After definenode has run, the management server has been set up with all the node information for CSM, and you are now ready to verify the node definitions. This section tells you how to verify and customize the cluster node definitions before the nodes are installed. Since the actual node installation has not happened yet, you can make changes to any of the node definitions at this time.

To determine whether the nodes have been defined, issue the lsnode command from the management server:

lsnode

The system responds with a line for each node that was successfully defined. If a node has not been defined, it will not appear in the output for lsnode.

To display all the information about each node, use the lsnode command, from the management server, with the -l (lowercase l, not uppercase i) option:

lsnode -l

The system responds with a list (output), containing extended information, for each node that was successfully defined. If a node has not been defined, it will not appear in the output for lsnode. Note that some of the attributes for a node might have null values at this point.

Note:
If a node has not been defined, it will not be installed.

If something needs to be corrected, you can either remove the node that was not successfully defined and then rerun the definenode command with the correct arguments, or you can make the necessary changes to the attributes of the node.

To remove a node before redefining it, use the rmnode command on the management server:

rmnode hostname

To change the attributes of a node, use the chnode command from the management server:

chnode hostname attr=value

See the man pages or the CSM for Linux: Administration Guide for more information about the lsnode, chnode, and rmnode commands.
