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.
Perform all steps in this procedure from a node of the global cluster.
For a zone-cluster node, follow the instructions in How to Remove a Node From a Zone Cluster before you perform this step.
On SPARC based systems, run the following command.
ok boot -x
On x86 based systems, run the following commands.
shutdown -g -y -i0 Press any key to continue

[ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ESC at any time exits. ] grub edit> kernel$ /platform/i86pc/kernel/#ISADIR/unix -B $ZFS-BOOTFS -x
The screen displays the edited command.
This change to the kernel boot parameter command does not persist over the system boot. The next time you reboot the node, it will boot into cluster mode. To boot into noncluster mode instead, perform these steps again to add the –x option to the kernel boot parameter command.
phys-schost# clnode clear –F nodename
If you have resource groups that are have rg_system=true, you must change them to rg_system=false so that the clnode clear -F command will succeed. After you run clnode clear -F, reset the resource groups back to rg_system=true.
phys-schost# clnode remove –F
If you are removing the last node in the cluster, the node must be in noncluster mode with no active nodes left in the cluster.
phys-schost# clnode status nodename
This example shows how to remove a node (phys-schost-2) from a cluster. The clnode remove command is run in noncluster mode from the node you want to remove from the cluster (phys-schost-2).
