Sun Cluster System Administration Guide for Solaris OS

ProcedureHow to Add a Node to the Authorized Node List

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

For hardware installation information, refer to the Sun Cluster 3.1 - 3.2 Hardware Administration Manual for Solaris OS or the hardware documentation that shipped with your server.

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

This procedure provides the long forms of the Sun Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix A, Sun Cluster Object-Oriented Commands.

  1. On a current cluster member, become superuser on a current cluster member.

  2. Ensure that you have correctly completed all prerequisite hardware installation and configuration tasks listed in the task map for Adding a Cluster Node.

  3. Start the clsetup utility.

    # clsetup

    The Main Menu is displayed.

  4. Type the number that corresponds to the option for displaying the New Nodes Menu and press the Return key.

  5. Type the number that corresponds to the option to modify the authorized list and press the Return key. Specify the name of a machine that can add itself.

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

  6. Verify that the task has been performed successfully.

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

  7. To prevent any new machines from being added to the cluster, type the number that corresponds to option to instruct the cluster to ignore requests to add new machines and press the Return key.

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

  8. Quit the clsetup utility.

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

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

Example 8–11 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 clsetup utility.]
# clsetup
[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.]
claccess allow -h phys-schost-3
    Command completed successfully.
[Select Prevent any new machines from being added to the cluster.]
[Quit the clsetup New Nodes Menu and Main Menu.]
[Install the cluster software.]
