You can boot a node so that the node does not participate in the cluster membership, that is, in non-cluster mode. Non-cluster mode is useful when installing the cluster software or performing certain administrative procedures, such as patching a node.
Become superuser on the cluster node to be started in non-cluster mode.
Shut down the node by using the scswitch and shutdown commands.
# scswitch -S -h node # shutdown -g0 -y -i0 |
Verify that the node is at the ok prompt.
Boot the node in non-cluster mode by using the boot(1M) command with the -x option.
ok boot -x |
Messages appear on the node's console stating that the node is not part of the cluster.
The following example shows the console output when shutting down node phys-schost-1 then restarting the node in non-cluster mode. The -g0 option sets the grace period to zero, -y provides an automatic yes response to the confirmation question, and -i0 invokes run level 0 (zero). Shutdown messages for this node appear on the consoles of other nodes in the cluster.
