Setting up Static IP

Steps to set up the static IP for IBM Fusion HCI appliance.

Before you begin

Download the installation preparation worksheet and review the network preparation section. To download the worksheets, see IBM Fusion HCI Installation worksheets.
If you plan to use Static IP instead of DHCP, you must have selected the Static IP assignment method in Stage 1 of the installation.
A fully functional DNS environment is a requirement for IBM Fusion HCI and OpenShift® Enterprise to work correctly. Adding entries into the /etc/hosts file is not enough because that file is not copied into containers that are running on the platform.

Important: If you are using static IP, then you do not have to do a DHCP setup.

Place your static servers in the same VLAN as IBM Fusion HCI.
Verify whether the DNS server is accessible from outside the IBM Fusion HCI by using either the ping <server-ipaddress> or the nslookup <server-ipaddress> command.

Note: The DNS server can be anywhere but must be reachable, that is, the installation and cluster must have access to your network.
Set up the DNS reservation for each node. For more information about setting up the DNS, see Setting up DNS.
Here, ensure that you use the same domain-name-servers value and option host name that you used in Static IP as they are interconnected. Make sure that the fixed addresses that you configure here is same in Static IP as well.
