Configuring HMP for Transparent Local Failover Support
•HMP does not support backward compatibility in the local failover and
•When HMP is configured in the local failover mode, all the resources in the cluster are utilized. If a resource fails in the cluster and is restored, HMP does not utilize that resource until another resource fails.
•Before running clic_start on all the nodes in the cluster, ensure that all the configured cards are connected in the cluster. In other words, before running the clic_start command, verify that all the cables are connected to the adapters and switches.
•If a resource in the cluster fails and is restored, perform the following steps to ensure full utilization of that resource:
—Shutdown Oracle RAC
—Execute the clic_shutdown command
—Execute the clic_start command
—Restart Oracle RAC
•After executing the clic_start command on all node in the cluster, ensure that you run Oracle RAC only after one minute (approximately).
•If all the trunks between the switches are down, then execute clic_shutdown followed by clic_start on all the nodes in the cluster, after replacing at least one trunk between the switches.
•Maintain at least one trunk between the switches when Oracle RAC is running in the cluster.
•If any of the nodes is shut down for administrative reasons, shut down Oracle RAC before executing clic_shutdown on that node. In such a case, Oracle RAC continues to be operational on all the other nodes in the cluster. When you bring up the node that was shut down, it joins the cluster.
