Troubleshooting 7-9 When Using an Ethernet Cluster Interconnect I Make sure that the Ethernet cluster interconnect components (adapters, cables, switches or hubs) are properly installed as specified in Chapter 5, "Installation and Configuration." I Make sure that the Ethernet cluster interconnect and the client LAN are connected to different Ethernet switches or hubs. I Use the ping utility to test the Ethernet cluster interconnect connections. For information about the ping utility, refer to "Verifying Cluster Communications" in Chapter 5, "Installation and Configuration." I Make sure that all Ethernet traffic not related to the Oracle data is using the client LAN, not the cluster interconnect. Unable to Ping the Cluster Interconnect or the Client LAN If you are using the recommended method of using static IP addresses, ensure that the hosts file and lmhosts files are properly set up. When Using an Ethernet Cluster Interconnect I Make sure that the Ethernet cables are properly connected and that the Ethernet switches or hubs are powered on. In a redundant Ethernet cluster interconnect, verify that all Ethernet adapters used as the primary cluster interconnect path are connected to the same switch and that all adapters used as the redundant cluster interconnect path are connected to the redundant switch. I Make sure that the Ethernet drivers are properly installed and configured on the cluster nodes. Verify that the Ethernet drivers for the cluster interconnect adapters are the same revision level on all cluster nodes. I If you are using two dual-port Ethernet adapters in each node to connect to both the client LAN and the Ethernet cluster interconnect, make sure that the cables are installed between the correct adapter ports and switches.

cables, switches or hubs) are properly installed as specified in Chapter 5,
“Installation and Configuration.”
■
Make sure that the Ethernet cluster interconnect and the client LAN are
connected to different Ethernet switches or hubs.

For information about the ping utility, refer to “Verifying Cluster
Communications” in Chapter 5, “Installation and Configuration.”
