Problem Summary: To provide highly available, per-node, logical IP communication over a private interconnect, Sun Cluster software relies on gateway routes on the cluster nodes. Flushing the gateway routes will break the per-node logical IP communication.
Workaround: Reboot the cluster nodes where the routes were inadvertently flushed. To restore the gateway routes, it is sufficient to reboot the cluster nodes one at a time. Per-node logical IP communication will remain broken until the routes have been restored. Quorum considerations must be observed while rebooting cluster nodes.
