following cluster characteristics:
• Cluster name — Displays the cluster name, cluster configuration file revision level, locking
type (either DLM or GULM), and basic fence timing properties used when a node joins a
cluster or is fenced from the cluster.
• Cluster — Displays each node of the cluster, specifying node name, node ID, number of
quorum votes, and fencing method for that node.
• Fence Device — Displays fence devices in the cluster. Parameters vary according to the type
of fence device. For example for a power controller used as a fence device, the cluster
configuration defines the name of the power controller, its IP address, login, and password.
• Managed Resources — Displays resources required to create cluster services. Managed
resources includes the definition of failover domains, resources (for example an IP address),
and services. Together the managed resources define cluster services and failover behavior
of the cluster services.
