Sun™ Cluster Environment: Sun Cluster 2.2

Managing Cluster Partitions

After the appropriate nodes are in the cluster, managing cluster membership becomes largely automated. If a failure occurs, the failed node is automatically configured out of the cluster. Rejoining the node to the cluster is performed using the scadmin startnode command.

Another situation that may require manual intervention can occur in a cluster with more than two nodes. In this case, multiple failures of the private interconnects will cause partitioning.

A partition is a group of nodes, each of which can communicate with nodes within the group, but not with nodes outside the group, see Chapter 2, “Sun Cluster 2.2 Architecture.” In most cases, the partition that becomes the cluster is automatically determined by ...
