scshutdown(1M) System Administration Commands scshutdown(1M) NAME
scshutdown - shut down a cluster SYNOPSIS
scshutdown [-y] [-g grace-period] [message] DESCRIPTION
Note - Beginning with the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more infor- mation about the object-oriented command set, see the Intro(1CL) man page. The scshutdown utility shuts down an entire cluster in an orderly fashion. Before starting the shutdown, scshutdown sends a warning message, then a final message asking for confirmation. Only run the scshutdown command from one node. The scshutdown command performs the following actions when it shuts down a cluster: o Changes all functioning resource groups on the cluster to an offline state. If any transitions fail, scshutdown does not com- plete and displays an error message. o Unmounts all cluster file systems. If any unmounts fail, scshutdown does not complete and displays an error message. o Shuts down all active device services. If any transition of a device fails, scshutdown does not complete and displays an error message. o Runs /usr/sbin/init 0 on all nodes. See init(1M) for more information. You can use this command only in the global zone. You need solaris.cluster.system.admin RBAC authorization to use this command. See rbac(5). OPTIONS
The following options are supported: -g grace-period Changes the number of seconds from the 60-second default to the time specified by grace-period. -y Pre-answers the confirmation question so the command can be run without user intervention. OPERANDS
The following operands are supported: message Is a string that is issued after the standard warning message The system will be shut down in ... is issued. If message contains more than one word, delimit it with single (') or double (") quotation marks. The warning message and the user-provided message are output when there are 7200, 3600, 1800, 1200, 600, 300, 120, 60, and 30 seconds remaining before scshutdown begins. EXAMPLES
