Testing the network settings of the operating system of a node

Before changing the address of the node in the KSMG application, we recommend verifying that the new network settings of your operating system are applied.

To test the network settings of the operating system of a cluster node:

1. In Technical Support Mode, connect to the node using the new IP address.
2. Check if the current network settings of the operating system match the settings that you have specified in the steps of the wizard. To view and check the settings of the operating system, use the following commands:
   • To test the network adapter settings:

     ip address

   • To test the default route and static route:

     ip route

   • To test the DNS server settings:

     cat /etc/resolv.conf

   • To test the domain name:

     hostname -f

3. Make sure the DNS server has a record for the new domain name of the node:

   host <domain name of the node>

   If the record for the domain name of the node is not found on the DNS server, check if the network settings are specified correctly. If necessary, modify the network settings of the operating system.

As a result, the network settings of the operating system on node are tested.
