You can boot a global-cluster node in noncluster mode, where the node does not participate in the cluster membership. Noncluster mode is useful when installing the cluster software or performing certain administrative procedures, such as updating a node. A zone-cluster node cannot be in a boot state that is different from the state of the underlying global-cluster node. If the global-cluster node is booted in noncluster mode, the zone-cluster node is automatically in noncluster mode.
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.
The clnode evacuate command switches over all device groups from the specified node to the next-preferred node. The command also switches all resource groups from global zones on the specified node to the next-preferred global zones on other nodes.
phys-schost# clnode evacuate node
phys-schost# shutdown -g0 -y
phys-schost# clzonecluster halt –n node zone-cluster-name
You can also use the clnode evacuate and shutdown commands within a zone cluster.
On SPARC based systems, run the following command.
ok boot -xs
On x86 based systems, run the following commands.
The GRUB menu appears.
For more information about GRUB based booting, see Booting a System in Booting and Shutting Down Oracle Solaris 11.3 Systems.
The GRUB boot parameters screen appears.
[ 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.
The following example shows the console output when node phys-schost-1 is shut down and restarted in noncluster mode. The –g0 option sets the grace period to zero, the –y option provides an automatic yes response to the confirmation question, and the –i0 option invokes run level 0 (zero). Shutdown messages for this node appear on the consoles of other nodes in the global cluster.
