How to Add a Node to the Authorized Node List

Before adding a machine to an existing cluster, be sure the node has all of the necessary hardware correctly installed and configured, including a good physical connection to the private cluster interconnect.

For hardware installation information, refer to the Sun Cluster Hardware Administration Manual for Solaris OS or the hardware documentation that shipped with your server.

This procedure permits a machine to install itself into a cluster by adding its node name to the list of authorized nodes for that cluster.

You must be superuser on a current cluster member to complete this procedure.

1. Be sure you have correctly completed all prerequisite hardware installation and configuration tasks listed in the task map for Adding and Removing a Cluster Node.

2. Type the scsetup command.

   # scsetup

   The Main Menu is displayed.

3. To access the New Nodes Menu, type 7 at the Main Menu.

4. To modify the authorized list, type 3 at the New Nodes Menu, Specify the name of a machine which may add itself.

   Follow the prompts to add the node's name to the cluster. You will be asked for the name of the node to be added.

5. Verify that the task has been performed successfully.

   The scsetup utility prints a “Command completed successfully” message if it completes the task without error.

6. Quit the scsetup utility.

7. Install and configure the software on the new cluster node.

   Use either scinstall or JumpStart^TM to complete the installation and configuration of the new node, as described in the Sun Cluster Software Installation Guide for Solaris OS.

8. To prevent any new machines from being added to the cluster, type 1 at the New Nodes Menu.

   Follow the scsetup prompts. This option tells the cluster to ignore all requests coming in over the public network from any new machine trying to add itself to the cluster.

Example—Adding a Cluster Node to the Authorized Node List

The following example shows how to add a node named phys-schost-3 to the authorized node list in an existing cluster.

[Become superuser and execute the scsetup utility.]
# scsetup
Select New nodes>Specify the name of a machine which may add itself.
Answer the questions when prompted.
Verify that the scconf command completed successfully.
 
scconf -a -T node=phys-schost-3
 
    Command completed successfully.
Select Prevent any new machines from being added to the cluster.
Quit the scsetup New Nodes Menu and Main Menu.
[Install the cluster software.]
