Troubleshooting 7-9 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 the 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 the Ethernet drivers for the 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. Node or Nodes Unable to Rejoin the Cluster I If you have an Ethernet cluster interconnect, use ping to ensure that the rejoined node or nodes can communicate with other nodes in the cluster. For information about using the ping utility to test redundant Ethernet cluster interconnect connections, see "Verifying Cluster Communications" in Chapter 5, "Installation and Configuration." I Make sure the OSDs have been properly installed on the affected node or nodes by running the OUI on the cluster's primary node. Click Installed Products and verify an entry for the OSDs exists.
