Use the crsctl check cluster command on any node in the cluster to check the status of the Oracle Clusterware stack.
You can check the status of the Oracle Clusterware stack on all nodes in the cluster with the -all parameter or you can specify one or more space-delimited nodes. If you do not specify either parameter, then Oracle Clusterware checks the status of the Oracle Clusterware stack on the local server.
You can use this cluster-aware command on any node in the cluster.
The crsctl check cluster command returns output similar to the following:
$ crsctl check cluster -all ***************************************************************** node1: CRS-4537: Cluster Ready Services is online CRS-4529: Cluster Synchronization Services is online CRS-4533: Event Manager is online ***************************************************************** node2: CRS-4537: Cluster Ready Services is online CRS-4529: Cluster Synchronization Services is online CRS-4533: Event Manager is online *****************************************************************
