How do I check network or node connectivity related issues?
Use component verifications commands like ‘nodereach’ or ‘nodecon’ for this purpose. For detailed syntax of these commands, type comp -help command on the command prompt. If the ‘comp nodecon’ command is invoked without -i, cluvfy will attempt to discover all the available interfaces and the corresponding IP address & subnet. Then cluvfy will try to verify the node connectivity per subnet. You can run this command in verbose mode to find out the mappings between the interfaces, IP addresses and subnets. Cluvfy will suggest interfaces for VIP and private interconnect if suitable interfaces are available. You can check the connectivity among the nodes through specific interfaces by specifying the interface name(s) through -i argument.
