You must run this command as root.
This command attempts to gracefully stop resources managed by Oracle Clusterware while attempting to stop Oracle High Availability Services on the local server.
If any resources that Oracle Clusterware manages are still running after you run the crsctl stop crs command, then the command fails. Use the -f parameter to unconditionally stop all resources and stop Oracle High Availability Services on the local server.
If you intend to stop Oracle Clusterware on all or a list of nodes, then use the crsctl stop cluster command, because it prevents certain resources from being relocated to other servers in the cluster before the Oracle Clusterware stack is stopped on a particular server. If you must stop the Oracle High Availability Services on one or more nodes, then wait until the crsctl stop cluster command completes and then run the crsctl stop crs command on any particular nodes, as necessary.
Before attempting to shut down the Oracle Clusterware technology stack on all nodes with an Oracle ASM instance running in parallel in an Oracle Clusterware standard Cluster with Oracle Flex ASM enabled, you must first relocate at least one Oracle ASM instance to another node where Oracle ASM is not running.
In Oracle Clusterware 11g release 2 (11.2.0.3), when you run this command in Solaris Sparc and Solaris X64 environments, drivers remain loaded on shutdown and subsequent startup. This does not happen in Linux environments.
