How to Add a Node to an Existing Cluster or Zone Cluster

Before adding an Oracle 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 Managing Hardware With Oracle Solaris Cluster 4.4 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 Oracle Solaris Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical.

  1. Ensure that you have correctly completed all prerequisite hardware installation and configuration tasks that are listed in the task map for Figure 14, Table 14, Task Map: Adding a Node to an Existing Global or Zone Cluster.
  2. Install the software on the new cluster node.

    Complete the installation of software of the new node as described in Installing and Configuring an Oracle Solaris Cluster 4.4 Environment.

  3. Use the scinstall utility on the new node to configure that node in the cluster.
    # scinstall
    

    Choose "Create a new cluster or add a cluster node", then "Add a Node to an Existing Cluster".

    See Configuring Oracle Solaris Cluster Software on Additional Global-Cluster Nodes (scinstall) in Installing and Configuring an Oracle Solaris Cluster 4.4 Environment.

  4. To manually add a node to a zone cluster, you must specify the Oracle 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 sc_ipmp0 is the IPMP group name.

    clzc:sczone>add node
    clzc:sczone:node>set physical-host=phys-cluster-3
    clzc:sczone:node>set hostname=hostname3
    clzc:sczone:node>add net
    clzc:sczone:node:net>set address=hostname3
    clzc:sczone:node:net>set physical=sc_ipmp0
    clzc:sczone:node:net>end
    clzc:sczone:node>end
    clzc:sczone>exit

    For detailed instructions on configuring the node, see Creating and Configuring a Zone Cluster in Installing and Configuring an Oracle Solaris Cluster 4.4 Environment.

  5. After you configure the node, reboot the node into cluster mode and install the zone cluster on the node.
    # clzonecluster install zone-cluster-name
  6. To prevent any new machines from being added to the cluster, from the clsetup utility type the number for the 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.
