Overview of Shutting Down and Booting a Cluster

The Oracle Solaris Cluster cluster shutdown command stops global cluster services in an orderly fashion and cleanly shuts down an entire global cluster. You can use the cluster shutdown command when moving the location of a global cluster, or to shut down the global cluster if an application error causes data corruption. The clzonecluster halt command stops a zone cluster that is running on a specific node or an entire zone cluster on all configured nodes. (You can also use the cluster shutdown command within a zone cluster.) For more information, see the cluster(8CL) man page.

In the procedures in this chapter, phys-schost# reflects a global-cluster prompt. The clzonecluster interactive shell prompt is clzc:schost>.


Note -  Use the cluster shutdown command to ensure proper shutdown of the entire global cluster. The Oracle Solaris shutdown command is used with the clnode evacuate command to shut down individual nodes. For more information, see How to Shut Down a Cluster, Shutting Down and Booting a Single Node in a Cluster, or the clnode(8CL) man page.

You can also evacuate a node by using the Oracle Solaris Cluster Manager browser interface. For Oracle Solaris Cluster Manager log-in instructions, see How to Access Oracle Solaris Cluster Manager.


The cluster shutdown and the clzonecluster halt commands stop all nodes in a global cluster or zone cluster, respectively, by performing the following actions:

  1. Takes all running resource groups offline.

  2. Unmounts all cluster file systems for a global cluster or a zone cluster.

  3. The cluster shutdown command shuts down active device services on a global cluster or a zone cluster.

  4. The cluster shutdown command runs init 0 and brings all nodes on the cluster to the OpenBoot PROM ok prompt on a SPARC based system or the Press any key to continue message on the GRUB menu of an x86 based system. For more information about GRUB based booting, see About Run Level Booting in Booting and Shutting Down Oracle Solaris 11.4 Systems. The clzonecluster halt command performs the zoneadm –z zone-cluster-name halt command to stop, but not shut down, the zones of the zone cluster.


Note -  If necessary, you can boot a node in noncluster mode so that the node does not participate in cluster membership. Noncluster mode is useful when installing cluster software or for performing certain administrative procedures. See How to Boot a Node in Noncluster Mode for more information.

Task
Instructions
Stop the cluster.
Start the cluster by booting all nodes. The nodes must have a working connection to the cluster interconnect to attain cluster membership.
Reboot the cluster.
