Sun Cluster System Administration Guide for Solaris OS

ProcedureHow to Add a Node to the Authorized Node List

Before adding a Solaris host or a virtual machine to an existing global cluster or a zone 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.

The phys-schost# prompt reflects a global-cluster prompt. Perform this procedure on a global 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 B, Sun Cluster Object-Oriented Commands.

  1. On a current global-cluster member, become superuser on the current cluster member. Perform these steps from a node of a global cluster.

  2. Ensure that you have correctly completed all prerequisite hardware installation and configuration tasks that are listed in the task map for Table 8–1.

  3. Start the clsetup utility.

    phys-schost# clsetup

    The Main Menu is displayed.

    Note –

    To add a node to a zone cluster, use the clzonecluster utility. See Step 9 for instructions to manually add a zone to a zone cluster.

  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. 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 that is trying to add itself to the cluster.

  8. Quit the clsetup utility.

  9. To manually add a node to a zone cluster, you must specify the Solaris host and the virtual node name. You must also specify a network resource to be used for public network communication on each node. In the following example, the zone name is sczone, and bge0 is the public network adapter on both machines.

    clzc:sczone>add node
    clzc:sczone:node>set physical-host=phys-cluster-1
    clzc:sczone:node>set hostname=hostname1
    clzc:sczone:node>add net
    clzc:sczone:node:net>set address=hostname1
    clzc:sczone:node:net>set physical=bge0
    clzc:sczone>add node
    clzc:sczone:node>set physical-host=phys-cluster-2
    clzc:sczone:node>set hostname=hostname2
    clzc:sczone:node>add net
    clzc:sczone:node:net>set address=hostname2
    clzc:sczone:node:net>set physical=bge0

    For detailed instructions on configuring the node, see Configuring a Zone Cluster in Sun Cluster Software Installation Guide for Solaris OS.

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

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

Example 8–1 Adding a Global-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.]
phys-schost# 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.]
