Perform this procedure if the installed node cannot join the cluster or if you need to correct configuration information. For example, perform this procedure on all nodes to reconfigure the transport adapters or the private-network address.
Before You Begin
Attempt to rerun cluster configuration of the node by using the scinstall utility. You can correct certain cluster node configuration failures by repeating Oracle Solaris Cluster software configuration on the node.
If you are unconfiguring a single-node cluster, skip to Step 2.
phys-schost# /usr/cluster/bin/claccess allow -h nodename
Specifies the name of the node to add to the authentication list.
You can also use the clsetup utility to perform this task. See How to Add a Node to an Existing Cluster or Zone Cluster in Administering an Oracle Solaris Cluster 4.4 Configuration for procedures.
phys-schost# shutdown -g0 -y -i0
ok boot -x
For more information about GRUB based booting, see About Run Level Booting in Booting and Shutting Down Oracle Solaris 11.4 Systems.
The screen displays the edited command.
phys-schost# cd /
phys-schost# /usr/cluster/bin/clnode remove
The node is removed from the cluster configuration but Oracle Solaris Cluster software is not removed from the node.
See the clnode(8CL) man page for more information.
phys-schost# /usr/cluster/bin/scinstall -r [-b BE-name]
Removes cluster configuration information and uninstalls Oracle Solaris Cluster framework and data-service software from the cluster node. You can then reinstall the node or remove the node from the cluster.
Specifies the name of a new boot environment, which is where you boot into after the uninstall process completes. Specifying a name is optional. If you do not specify a name for the boot environment, one is automatically generated.
See the scinstall(8) man page for more information.
If the cluster node that you are removing is at least partially configured with the cluster, running the clnode remove command might exit with errors such as Node is still enabled. If such errors occur, add the –F option to the clnode remove command.
Before you reinstall or reconfigure Oracle Solaris Cluster software on the node, refer to Figure 3, Table 3, Task Map: Installing the Software. This table lists all installation tasks and the order in which to perform the tasks.
To physically remove the node from the cluster, see How to Remove an Interconnect Component in Managing Hardware With Oracle Solaris Cluster 4.4 and the removal procedure in the Oracle Solaris Cluster guide for your storage array.
