Perform this procedure on existing global-cluster nodes to prepare the cluster for the addition of new cluster nodes.
Before You Begin
Perform the following tasks:
Ensure that all necessary hardware is installed.
Ensure that the host adapter is installed on the new node. See the Oracle Solaris Cluster Hardware Administration Manual.
Verify that any existing cluster interconnects can support the new node. See the Oracle Solaris Cluster Hardware Administration Manual.
Ensure that any additional storage is installed.
phys-schost# clsetup
The Main Menu is displayed.
The clsetup utility displays the message Command completed successfully if the task is completed without error.
phys-schost# clinterconnect show
You must have at least two cables or two adapters configured before you can add a node.
phys-schost# clsetup
Follow the instructions to specify the name of the node to add to the cluster, the name of a transport adapter, and whether to use a transport switch.
phys-schost# clinterconnect show
The command output should show configuration information for at least two cluster interconnects.
phys-schost# cluster show-netprops
The output looks similar to the following:
=== Private Network === private_netaddr: 172.16.0.0 private_netmask: 255.255.240.0 max_nodes: 64 max_privatenets: 10 max_zoneclusters: 12
Go to How to Configure Oracle Solaris Cluster Software on Additional Global-Cluster Nodes (scinstall).
Go to How to Change the Private Network Configuration When Adding Nodes or Private Networks. You must shut down the cluster to change the private IP address range. This involves switching each resource group offline, disabling all resources in the cluster, then rebooting into noncluster mode before you reconfigure the IP address range.
Next Steps
Configure Oracle Solaris Cluster software on the new cluster nodes. Go to How to Configure Oracle Solaris Cluster Software on Additional Global-Cluster Nodes (scinstall) or How to Configure Oracle Solaris Cluster Software on Additional Global-Cluster Nodes (XML File).
