clstartstop command allows the VIOS admin user to start or stop one or more number of cluster nodes, or some time complete cluster nodes will be stopped. Running stop command will consider the node as down and will be part of cluster but it will display as down until the cluster is not started on it.



Below is the usage assuming there are four nodes in box cluster vios1, vios2, vios3 and vios4

$ clstartstop -stop -n box -m vios3,vios4 
        Stops the cluster operations on nodes vios3 and vios4.
 
$ clstartstop -starts -n box -m vios3,vios4
        Starts the cluster operations on nodes vios3 and vios4 making them join back to cluster.

$ clstartstop -stop -n box -a
        Stops all the nodes cluster services for maintenance

$ clstartstop -start -n box -a
       Starts all the cluster nodes.

The arguments can be either provided with -m on -a where usage is 
        clstartstop {-start | -stop} [-n cluster_name] {-m vios_names_coma_seperated[,...] | -a}
