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
For more information about GRUB based booting, see About Run Level Booting in Booting and Shutting Down Oracle Solaris 11.4 Systems.
[ 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
# clnode clear -F node-to-be-removed
Verify the node removal by running clnode status nodename.
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
You could also choose to remove the node from the cluster and uninstall the Oracle Solaris Cluster software at the same time. Change to a directory that does not contain any Oracle Solaris Cluster files and type scinstall -r.
See Managing Hardware With Oracle Solaris Cluster 4.4 for instructions.
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).
Remove the node from the cluster: phys-schost-2# clnode remove phys-schost-1# clnode clear -F phys-schost-2 Verify node removal: phys-schost-1# clnode status -- Cluster Nodes -- Node name Status --------- ------ Cluster node: phys-schost-1 Online
To uninstall Oracle Solaris Cluster software from the removed node, see How to Uninstall Oracle Solaris Cluster Software From a Cluster Node in Installing and Configuring an Oracle Solaris Cluster 4.4 Environment.
For hardware procedures, see the Managing Hardware With Oracle Solaris Cluster 4.4.
For a comprehensive list of tasks for removing a cluster node, see Figure 15, Table 15, Task Map: Removing a Node.
