RoleOfNode indicates whether the Cluster nodes are peers (value = 2), connected in a master-slave/primary-secondary relationship (values = 3 for primary, 4 for secondary), available in a standby configuration (5) or of some other (1) or unknown (0) relationship. In a System/390 environment, the nodes are identified as \"Base Plex\" (value=6) or \"Enhanced Plex\" (value=7).
