+Perform specified activation command on a remote cluster node (the same to running

+Currently tested only for corosync clusters (\fB-I\fP \fIcorosync\fP option to clvmd)
+for corosync versions from 2.0.
+If corosync configuration has node names in a nodelist (nodelist.node.X.name = name
+in CMAP tems) or node names are used for ring0_addr (nodelist.node.X.ring0_addr = name),
+then that names may be used as NodeID. Otherwise numeric node IDs should be used.
